What is Concrete admixtures? Concrete admixtures, also known as concrete additives, is a chemical substance that is added in the process of mixing concrete, accounting for less than 5% of the cement mass, and can significantly improve the performance of concrete. The characteristics of concrete admixtures are many varieties and small dosage, which have a great influence on the performance of concrete, and have the characteristics of less investment, quick effect, and significant technical and economic benefits. With the continuous advancement of science and technology, concrete additives have been used more and more, and admixtures have become the fifth important component of concrete in addition to the four basic components. What are the types of concrete admixtures? If concrete admixtures are classified by function, there are five different classes of chemical admixtures: air-entraining admixtures, water-reducing admixtures, retarders, accelerators, and plasticizers (superplasticizers). What are concrete admixtures used for? Concrete admixtures are added to water-cement mixtures to extend the life of concrete, control setting and hardening, and fix the general properties of concrete. They can be powder or liquid additives. Concrete admixtures can be added at the point of manufacture or on the job site.

The Development History of Boron Nitride

Boron nitride, a synthetic ceramic materials with beneficial chemical and physical characteristics is available. In 1954, the Carborundum Corporation first produced it commercially. Saint-Gobain purchased it in 1996. Saint-Gobain Borion Nitride, the worldwide leader in hexagonal BN solutions, is now the market leader. In fact, 60 years worth of experience has been gained by the […]

Silicon Nitride structures and properties

Silicon Nitride HTML3N4 contains two kinds of crystal structures: a granular Crystal and B-Si3N4 are needle crystals. Each of these three-dimensional networks are composed of common verices of [SN4] Tetrahedron. They both belong to the hexagonal system. Their differences lie in the order and number of [SiN4] trihedral layers. The hexagonal ring layer of [SiN4] […]

The Property And Application of Aluminum Nitride

Aluminum nitride (atomic crystal) is a non-toxic metal. It is white to off-white in color. What property does aluminum nitride have? AlN can stabilize up to 2200. It has a high room temperature strength and slows down with increasing temperature. The thermal conductivity of aluminum nitride and its low thermal expansion coefficient make it an […]
