Starch ether is the polysaccharide compound extracted from natural plants, with the same chemical structure and similar properties compared with cellulose ethers. Its basic properties are as follows: Solubility: dissolve in cold water Particle size: ≥98% (80 mesh sieve] Viscosity: 300-800CPS Moisture: ≤10% Color: white or light yellow Used in building mortar, starch ether can.. read more →

What is bentonite? A: Bentonite, also known as montmorillonoid, is the layered aluminosilicate with montmorillonite as the main component. The cationic species between layers of bentonite determine the type of bentonite. If the interlayer cation is Na +, it is called sodium bentonite; if Ca+, it is called calcium bentonite; if H+, it is called.. read more →

What is fly ash? What are the varieties? A: Fly ash is the powder collected from the flue gas of the pulverized coal-fired power plant boiler and belongs to the mixed materials of pozzolanic activity. Its main components are silicon, aluminum and iron oxides, with potential hydration activity. Fly ash is gray brown and usually.. read more →

What is the active mineral admixture? What are the varieties? The active mineral admixture is the pozzolanic admixture, with silicon oxide and aluminum oxide as the main components. It does not have or have only very low gelling properties itself, but in the presence of water, can be chemically combined with calcium hydroxide to generate.. read more →

(1) The fly ash of good quality has a water-reducing effect, so it can reduce the water demand of mortar; the morphological effect and micro-aggregate effect of mortar can improve the density, fluidity and plasticity of mortar and reduce bleeding and segregation, and can also extend the setting time of mortar. After adding fly ash,.. read more →

Fly ash is the remaining ash content after pulverized coal Combustion in the power plant and belongs to industrial wastes. Fly ash is a mechanical mixture of various particles, of which most are spherical glass body, and has a larger specific surface area. Its mineral compositions are mainly glass phase, mullite, quartz, hematite, magnetite and.. read more →

Q: What is the cementing material? And what types? A: Cementing materials are generally divided into two categories, inorganic and organic cementing materials. The cementing material generally used in buildings refers to the inorganic cementing material. It refers to such a category of inorganic powder material as is mixed with water or the aqueous solution.. read more →

In the selection of aggregates used for building mortar, the following factors need to be taken into account. (1). Particle Size Gradation The effect of aggregate on the workability of mortar depends on the water absorption rate, fineness and gradation of aggregate. The larger the water absorption rate of aggregate is, the greater the water.. read more →

The aggregates in the mortar are inert materials not involved in the chemical reaction, and play the role of framework or padding. Aggregates can be used to adjust the density of mortar and control the shrinkage performance of materials. The particle diameter of fine aggregate used in the mortar is generally less than 5mm, so.. read more →

Since masonry cement is mainly used for the preparation of building mortar, it places requirements on the water retention, not less than 80%. The water retention of mortar refers to the weight of the water retained after water absorption treatment, expressed in the mass percent of original water amount. read more →
