Methyl hydroxyethyl cellulose ether (MHEC) and methyl hydroxypropyl cellulose ether (HPMC) are collectively referred to as methyl cellulose ether (Methyl Cellulose), referred to as MC. Methyl cellulose ether is one of the essential additives in dry-mixed mortar, which mainly plays the role of water retention and thickening. Methyl cellulose ether is a powdery cellulose ether produced by the […]
Now the Redispersible Polymer powder commonly used is mainly vinyl acetate-ethylene (referred to as VCAE) and vinyl acetate-vinyl tertiary acid (referred to as Ve0Va). Improving the bonding tensile strength of cement mortar and various substrates is the most crucial characteristic of vinyl copolymers, especially its ability to withstand significant changes in ambient temperature. In addition, […]
River sand and quartz sand are essential aggregates for dry-mixed mortar products and play an important role in the formulation system. Its roundness, particle size, water, and mud content directly affect cement mortar’s bond hardness, compressive strength, and construction performance. For dry-mixed mortar products, typically, there are rigorous quality and performance requirements of the aggregate. […]
Mica is a highly complex silicate mineral, often in the form of scales, and its main component is alumina containing silicon and potassium, which is flaky and elastic. In the application of coatings, it can increase the toughness of the coating film, reduce cracking, and improve weather resistance, salt resistance, electrical conductivity, and water resistance. […]
Talc powder is made by grinding natural talc ore after peeling off the iron oxide on the surface. The main component is magnesium silicate. Talc is a phyllosilicate and hydrous magnesium silicate mineral. There are few natural pure talc mines, and most of them are associated with other mineral impurities. The standard associated minerals are […]
The primary raw material for lime production is natural rock (limestone, dolomite, chalk, etc.) with calcium carbonate as the main component. In addition to producing lime with natural raw materials, another source of lime is by-products of the chemical industry (such as calcium carbide slag when calcium carbide is used to produce calcium hydroxide, the […]
Ordinary Portland cement is the most widely used type of cement in dry-mixed mortar products. Portland cement clinker is mixed with 6% ~ 15% mixed materials and the appropriate amount of gypsum to make a hydraulic cementitious material called ordinary Portland cement (referred to as ordinary cement), and its code is P ・0. The maximum […]
(4) Stability The uniformity of volume change of cement paste after hardening is called the volume stability of cement. After adding water into the cement, it gradually hydrates and hardens, and the hardened cement paste can maintain a particular shape with no cracking, deformation, or collapse. Generally speaking, in addition to the expansion of cement […]
Portland cement Portland cement is the most important inorganic bonding material in dry-mixed mortar products. After adding water to make slurry, it is a cementitious material that can harden in air and in water . Portland cement can be distinguished by performance and use, and can be divided into general-purpose cement, such as ordinary Portland […]
With the elimination of solid clay bricks, various new wall materials come out, such as aerated concrete bricks, fly ash bricks, shale bricks, aerated concrete blocks, lightweight GKC partition boards, and other new wall materials. Due to the advantages of lightweight, high strength, no environmental damage, and land resource protection, it is increasingly popular among […]
