Water-reducing agent solution for these three

The water-reducing agent should be used with concrete admixture, which will reflect the water reduction effect. Cement quality is therefore a direct factor of the actual effect of water-reducing agent.

Different cement types require different strategies when encountering "problem" cement.

High alkali cement

A cement that contains a lot of alkali is called high-alkali. Alkali in high-alkali is usually higher than that in conventional cement.

The high-alkali cements have a high degree of alkalinity. This can impact the performance. High-alkali Cement can encourage the setting reaction, which is beneficial to the early development of strength in concrete. High-alkali Cement can also increase the fluidity of cement, making it more workable and easier to pump.

But there are also some issues with high-alkali clinkers. As an example, high alkali cements can reduce the efficiency of water-reducing agents and cause concrete to lose its slump faster. High-alkali cement may also lead to corrosion and carbonation problems in the concrete.

High-alkali Cement can benefit from water-reducing agents containing a higher content of sodium sulfate. High-alkali cement contains a high amount of alkali, which accelerates C3A's dissolution. Sodium sulfate reacts with C3A, forming AFt crystals. This can improve the fluidity in cement mortar.

Low-alkali sulfur-deficient cement

Low alkali-sulfur cement is a cement with a lower sulfate level than normal cement. Ordinary cement is high in sulfate. It reacts with water and the sulfate forms crystals that cause cracks and expand the concrete.

Reduced sulfate cement reduces the impact of the Alkali-aggregate Reaction (Alkali-silica Reaction) in concrete. The alkali silica reaction in concrete is caused by the reaction between the cement and the aggregate's silicates. It causes expansion and cracking. The use of low-alkali cements that are sulfur-deficient can help reduce this reaction, and increase the durability and life of the concrete.

Due to the lower sulfate contents, water reducers work less well with low alkali-sulfur cement. Water-reducing agents can cause concrete to lose slump quickly if they are used in excess. In this case, the conventional method of using water-reducing agents may be ineffective. Instead, it is recommended to choose a water reducing agent that contains sulfate.

High C3A cement content

Cement with a high C3A-content is one that contains a large amount of C3A. C3A is a mineral found in cement which reacts with the water to produce an expansive substance when it hydrates. Cements with high C3A contents have a faster setting time and higher early strength. They are ideal for projects requiring rapid strength development and rapid setting.

Cement with a high C3A percentage can cause some problems. C3A and sulfate react to form sulphoaluminate. This can cause concrete to expand or crack. In humid environments, high C3A cements can produce corrosive Calcium Sulfate Precipitates, which may affect the durability of concrete and steel structures.

Cement containing high C3A has a higher adsorption rate of water-reducing agents. This will result in fewer fluidity and slump properties of concrete. If you are using a water-reducing chemical, choose a water-reducing chemical that has a high sulfate content or a retarder which contains hydroxycarboxylate. These will help reduce C3A adsorption and improve concrete fluidity.

There are two types of products that reduce water: one is the naphthalene product, and another is polycarboxylic acids. The main difference in water reduction is the naphthalene. It is high-efficiency, and polycarboxylic is high-performance. For general foam concrete, the naphthalene cubic addition is between a few hundred to a kilogram.

It has been widely used for high temperature resistance, wear resistance and chemical corrosion resistance. Place.

Structure of Molybdenum Carbide Mo2C

Metal carbides are generally considered to have interstitial alloy structures. In common interstitial alloys, metal atoms are arranged in the form of face-centered cubic (FCC), hexagonal dense packing (HCP), and simple hexagonal (HEX), and non-metallic atoms enter the space between the metal atoms. The most common types of gaps between metal atoms are octahedrons and triangular prisms. The crystal structure of metal carbides depends on geometric and electronic factors. The geometric factor can be described by Hager's rule of thumb: when the atomic ratio of nonmetal to metal is below 0.59, simple crystal structures are formed. Interestingly, although metal carbides have simple crystal structures, few of these compounds have the same crystal structure as their parent metals. For example, molybdenum metal has a body-centered cubic structure, while its stable carbides have a hexagonal close-packed structure, and oxycarbides have a face-centered cubic structure. Another factor that determines the crystal structure of interstitial alloys is the electronic factor. The bonding in these compounds results from the cooperation between the sP orbitals of nonmetals and the SPD orbitals of metal atoms.

Application of Aluminum Diboride AlB2 Powder

The Biden administration plans to ease sanctions on Venezuelan oil to allow more of the country's crude to reach Europe.  

The U.S. will allow European companies still operating in Venezuela to immediately transfer more oil to the continent, while allowing Chevron to negotiate a resumption of operations in Venezuela, according to people familiar with the matter.  Venezuela's OPPOSITION, which is backed by the United States, is understood to favor the move.  Tight global oil supplies have sent crude and fuel costs soaring, threatening to add to already high inflation.  Increasing Venezuelan crude exports would help ease supply constraints while also helping to reduce Europe's dependence on Russian energy.

The US has sought to encourage talks between the Venezuelan government and the US-backed opposition to open the way to free and fair elections by extending a limited license held by Chevron to allow the oil company to maintain its operations in Venezuela and negotiate future operations.  

The United States reportedly did not extend a permit to Allow Chevron to drill and sell Venezuelan crude, as the company had hoped.  

The license extension will allow Chevron to negotiate with State-run Petroleos de Venezuela SA, with which it has a joint venture.  Previously, the company could not directly negotiate with any officials sanctioned by the United States.  Chevron has been lobbying the United States to allow it to drill for Venezuelan crude and sell it on world markets to help lower energy prices amid the Russia-Ukraine war.

Affected by the ever-changing international situation, the supply and prices of many commodities like the Aluminum Diboride AlB2 Powder,Overview of Aluminum Diboride AlB2 Powder,Application of Aluminum Diboride AlB2 Powder,Aluminum boride AlB2 powder price,Aluminum boride AlB2 powder supplier are still very uncertain.

Overview of Aluminum Diboride AlB2 Powder

Aluminum boride (AlB2) is a binary compound formed from aluminum and boron. It is a red solid under normal temperature and pressure. It loses surface gloss when heated. Stable in cold dilute acid, decomposed in hot hydrochloric acid and nitric acid.

{xunruicms_img_title}

Aluminum boride (AlB2) is one of two compounds of aluminum and boron, the other being AlB12, commonly known as aluminum boride. AlB12 is a black glossy monoclinic crystal with a specific gravity of 2.55 (18°C). It does not dissolve water. The AlB2 single crystal is parallel to the hexagon of the substrate.

The structure of aluminum diboride (AlB2) is similar to that of graphite flakes. There is an Al atom between the B atom and the B atom, which is very similar to the structure of magnesium diboride. AlB2 single crystals exhibit metallic conductivity along an axis parallel to the hexagonal plane of the substrate.

Aluminum boride is considered a hazardous substance because it reacts with acids and hydrogen to produce toxic gases. For example, it reacts with hydrochloric acid to liberate borane and aluminum chloride.

The crystal structure of AlB2 is often used to describe the prototype structure of intermetallic compounds. There are various structural types in the AlB2 structural family.

Application of Aluminum Diboride AlB2 Powder

Aluminum boride is an ionic compound with a hexagonal crystal structure. Aluminum boride with an absolute temperature just above 40K (equivalent to -233°C) becomes a superconductor. Its actual working temperature is 20 ~ 30K. To achieve this temperature, we can use liquid neon, liquid or closed cycle refrigerators to accomplish cooling. These methods are simpler and more economical than the current industrial use of liquid helium to cool niobium alloys (4K). Once doped with carbon or other impurities, magnesium diboride retains superconductivity as good or better than niobium alloys in a magnetic field, or with an electric current flowing through it.

Aluminum boride is a random (or rhombic) white or pale yellow powder. Can be used as: non-toxic flame retardants, plastics, rubber, textiles, coatings, superconducting magnets, transmission lines, sensitive magnetic field detectors.

Preparation method of tungsten oxide

Hasad Foods, the agricultural investment arm of Qatar's sovereign wealth fund, said the government would increase its grain reserves from 250,000 tons to 300,000 tons in the near future, which is enough to feed the population for six months.  

With a lot of deserts, Qatar suffers from water shortages, and Qatar depends on food imports for a long time. Recently, the ongoing tension in Ukraine has caused global food supply tension and rising prices.

In addition to that, the geopolitical situation also affects the supply and prices of many commodities like the tungsten oxide, tungsten oxide overview, tungsten oxide application, tungsten oxide supplier, tungsten oxide price.

Tungsten oxide overview

Tungsten trioxide is a powder metallurgy raw material for the production of cemented carbide and tungsten products. According to the national standard (GB/T 3457-1998), it is divided into two types, namely tungsten trioxide (referred to as yellow tungsten), molecular formula is WO3, and blue tungsten oxide (referred to as blue tungsten, is a mixed tungsten oxide), molecular formula W20O58. Yellow tungsten is light yellow crystalline powder, blue tungsten is dark blue or blue-black crystalline powder.

Preparation method of tungsten oxide

1. Ammonium tungstate method: The tungsten concentrate is hydrolyzed by sodium hydroxide, neutralized with hydrochloric acid, and then reacted with ammonium chloride to generate ammonium tungstate, which is then added with hydrochloric acid for acid hydrolysis to generate tungstic acid, which is then decomposed by roasting. , pulverized to obtain tungsten trioxide.

2. Hydrochloric acid decomposition method of tungstate. The saturated aqueous solution of sodium tungstate Na2WO4, calcium tungstate CaWO4 and other tungstate salts is heated, and the solution is slowly added dropwise into 2-3 times excess boiling concentrated hydrochloric acid by molar ratio. According to the above reaction, yellow tungstic acid is precipitated. At this time, if the dripping speed is too fast or the liquid temperature drops, suspension or colloidal precipitation is likely to be formed, which brings difficulties to the next treatment. After the dropwise addition, heating was continued on a water bath for 1 h, and the precipitate became easy to filter. After standing, it was washed several times with 5% ammonium nitrate aqueous solution to completely remove Cl-. After filtration, it is dried at 120 °C, and finally heated to 600 °C, the tungstic acid is completely dehydrated and becomes tungsten trioxide.

3. Thermal decomposition of ammonium paratungstate. Put ammonium paratungstate (NH4) 10W12O41·11H2O purified by recrystallization method into a porcelain crucible, and when heated to above about 400 ℃, ammonia volatilizes to obtain tungsten trioxide.

Why does properly poured concrete end up cracking

It is very easy to cause concrete cracking if the construction or maintenance are not done correctly. What are then the five main causes of cracking concrete?

1. The cement proportion problem: Some workers in construction will add more water for a more fluid concrete. However, this will result in an increase in water-cement ratio. This will cause the concrete to harden too quickly, and lead to cracking.

2. Transport and mixing issues: If mixing and transporting concrete takes too much time, the water in the concrete will evaporate quickly. concrete . This leads to a concrete that is weaker on the construction site, unable to meet construction specifications.

3. Construction speed

4. Maintenance is unreasonable. During the period of maintenance, if late watering isn't maintained, the result will be the Cracking phenomenon Later in the year, concrete will be used. Concrete is used in the future. Concrete Surface Watering You can water the concrete often to speed up the drying process. Concrete will shrink if it is not watered. Late cracking occurs when concrete strength is decreased.

5. Environmental factors: If the environment at the construction site is relatively dry and there is high temperature, wind, or both, then the evaporation of the concrete surface will be accelerated. The result is cracking on the concrete's surface. Concrete constructions are most likely to crack in the winter or summer because of the temperature differences.

Solution: Add an agent to prevent cracking. A variety of inorganic composite materials can prevent over 80% of the foam cement from cracking. Add 2-3 kilograms of anti-cracking material per cubic meter.
