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…
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.…
Adding polycarboxylate superplasticizer can make the compressive strength of precast concrete reach 40MPa grade at 8h to 18h.…
Early strength admixture refers to the admixture that can improve the early strength of concrete and has no significant effect on the later strength.Superplasticizer for concreter is a concrete admixture that can reduce the amount of mixing water whi…
Superplasticizer used in concrete refers to the fact that after mixing, it can reduce the water demand of concrete under the condition of maintaining basically the same fluidity, thereby improving the strength and durability of concrete, or under the…
According to CBC Metal: As of February 28 , the average price of China's graphite electrode market was RMB 20818/ton, up 5.17% from the beginning of the year and 44.48% from the same period of the previous year; the graphite electrode market as a who…
What does high-purity graphite look like? High-purity Graphite Powder is graphite with high carbon contents. High-purity, graphite powder has a very high carbon content. High-purity powder is therefore called graphite. It has higher high-temperature…
What is Nitinol alloy? Ni-Ti and nickel alloys contain 50% and 50% of titanium, while nickel and titanium account for each half. It is possible to adjust its temperature range by changing the composition. The lower the Ni-Ti–Noel alloy's nickel conte…
