A cement foaming agent based on animal protein is made mainly from keratin proteins from the horns. This causes it to have an unpleasant odor. Coproduct, which is obtained through a variety of chemical reactions as well as physical treatment, can be…
In the process of concrete mixing, the mixing method of admixture has a great influence on the effect of admixture.…
Admixtures can be used for almost all kinds of concrete, but suitable admixtures must be selected according to engineering needs, construction conditions and construction technology.…
Thermal insulation materials refer to materials or material composites that have significant resistance to heat flow.…
Lightweight foamed concrete, also known as foamed cement, is a lightweight porous concrete product made from foaming agent aqueous solution into foam, and then adding foam to the slurry made of cement-based cementitious materials, aggregates, admixtu…
The open-cell foam concrete is an excellent sound absorption material, while the closed-cell foam concrete is an excellent sound insulation material.…
Foam concrete contains a large number of closed pores, the air in the pores is a good adiabatic medium, which can cut off the heat exchange.…
Before construction, ensure that all kinds of instruments used during construction can operate normally, check their status and break the work, and the materials must be in place.…
Foamed concrete is a highly entrained sand cement with at least 20% air volume in the cured product.…
Foam concrete has a low density. In practical application, the density grade of ordinary foam concrete is 300 kg/m3~1200kg/m3.…
Foam concrete is a highly workable low-density material containing up to 80% air.…
This article will continue to talk about the influences of concrete foaming agent on foam concrete.…
According to British media reports, researchers have recently developed a smart contact lens that enables the wearer to have "infrared night vision". Sandwiching graphene between the lenses allowed the construction of a sensor with the abil...…
TEP75, a novel cationic suprafactant from plant-derived cationic surfactants is a replacement for cationic conditioning agent such as polyaquaternium salts or octadecyltrialtrimethyl chloride. About Di (palmiticcarboxyethyl) hydroxyethyl methyl amm…
Polypropylene PP fiber has the advantages of high strength, good toughness, good chemical resistance and antimicrobial resistance, and low price, so it is widely used in ropes, fishing nets, safety belts, luggage belts, safety nets, sewing threads, c…
