What is quartz silica powder?…
When the same polycarboxylic acid sloughing agent is used but different cement is used, it is possible that this polycarboxylic acid sloughing agent has good compatibility with one kind of cement but poor compatibility with another cement, and when u…
Polycarboxylate superplasticizer is the third generation of high performance superplasticizer after common superplasticizer and superplasticizer.…
Silicon nitride is a compound of silicon and nitrogen. Si3n4 is the most thermodynamic stable in silicon nitride.…
Powder defoamer is a solid powder defoamer. Powder defoamer is often used in the building materials industry, which can more quickly eliminate the foam problems caused by technological problems in the construction industry.…
Recently, OPEC and the International Energy Agency (IEA) have made two different judgments on oil demand forecasts, which makes the already unpredictable price of crude oil even more complicated.OPEC believes that as rising prices put pressure on bus…
Because the steric hindrance of the extended polymer side chain effectively hinders the secondary agglomeration between cement particles, so the product has high dispersion performance and can maintain this performance for a long time to realize the…
Polycarboxylate superplasticizer has more advantages than traditional naphthalene and aliphatic superplasticizer in mixing high strength grade concrete, but its advantages of high water reduction cannot be brought into full play when the strength is…
Natural river sand has been exhausted after decades of large-scale mining, concrete production enterprises began to use machine-made sand as fine aggregate on a large scale.…
Recently, the EU proclaimed new sanctions on Russia, including coal, timber, rubber, cement, and fertilizer, as well as high-end seafood titanium powder. General:Can be used in pyrotechnic fuzes and combustible compositions, photographic…
If the compatibility of polycarboxylate superplasticizer and cement is not good, the concrete mixture is prone to some problems, such as segregation, bleeding, greater slump loss, shorter setting time and so on, so that the concrete mixture can not b…
The wide application of mineral admixtures mainly derived from industrial solid wastes diversifies the composition of cementitious materials, which is one of the main characteristics of modern concrete.…
Roche and its subsidiary TIB Molbiol have developed a series of tests for the detection of the monkeypox virus, the Switzerland-based pharmaceutical company announced. The monkeypox virus is a close relative of the smallpox virus, belonging to orthp…
Is boron amorphous or crystalline?Boron can be prepared in several crystalline and amorphous forms. The well-known forms of crystallization are α-rhombohedral (α-R), β-rhombohedral (β-R) and β-tetragonal (β-T). In spec…
With the quick growth of the construction sector, the needs for structure material efficiency are continually increasing. Amongst these, concrete, as one of the most vital structure materials, has actually ended up being a prime focus for many resear…
