Recently, the price of cellulose ether has continued to rise, and the cost of chemical raw materials has soared almost across the board since the beginning of 2021

The MIKEM test shows that when the HPMC content is 0.2%, the consistency of the thermal insulation mortar slurry reaches the maximum, and the water retention rate is higher; continue to increase the HPMC content, the consistency begins to decrease, but the water retention rate is not improved significantly.

Polycarboxylate superplasticizer is formed by copolymerization of unsaturated monomers containing carboxyl and other monomers, making the mixed concrete have excellent water reduction effect, slump loss control, strength improvement, and environmental protection, and the like.

Starch is a polysaccharide polymer compound composed of glucose. There are two kinds of molecules, linear and branched, called amylose (content about 20%) and amylopectin (content about 80%).

At construction sites, water-reducing agents are often added to concrete to reduce the internal gap, lower the water-cement ratio, and increase the strength.

Concrete additives, called admixtures for short, are substances used to improve the performance of concrete. As a common additive in construction engineering, concrete admixture has become essential in construction engineering.

Adding food additives to instant noodles within the permitted legal limits will not harm health. Some food additives can even enhance the quality of instant noodles.

The frost resistance of concrete is mainly related to the internal pore structure of the concrete, the age of freezing, the degree of water saturation, the strength of the concrete, and other factors. The pore structure of the concrete plays a crucial role in the frost resistance of the concrete.

The durability of concrete is directly related to impermeability. The penetration of concrete determines, to a large extent, that concrete is vulnerable to external adverse factors. Therefore, to improve the durability of concrete, the impermeability of concrete must first be improved.
