Admixtures that can greatly reduce the amount of mixing water under the condition that the slump of concrete is basically the same are called superplasticizers.…
Polycarboxylate superplasticizer is an important additive to ensure the strength of concrete and achieve pumping performance, and plays a pivotal role in improving and improving the operability of concrete construction. In this paper, according to th…
Polycarboxylate superplasticizer is the third generation of high-performance water-reducing agent after ordinary water-reducing agent and high-efficiency water-reducing agent.…
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…
As an admixture, superplasticizer is added to concrete to reduce water consumption and increase the strength of concrete. At present, the high-performance water-reducing agents used in concrete engineering are mainly polycarboxylic acid superplastici…
With the wide application of polycarboxylate superplasticizer, the requirement of concrete early strength in practical engineering is more and more prominent, so the polycarboxylate superplasticizer has been the focus of research to meet the early st…
After the pce superplasticizer is added to the cement, the sodium aluminate and sodium carbonate in its main components react rapidly with the gypsum in the cement to form sodium sulfate in the alkaline solution, so that the gypsum loses its original…
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…
Polycarboxylate superplasticizer has high surface activity and good foam retention, which will affect the strength of concrete due to excessive gas content.…
Concrete superplasticizer is one of the concrete admixtures which is used most frequently. It can increase the plasticity of concrete and change the strength of concrete.…
Superplasticizer admixture for concrete is one of the most used concrete admixtures, which can increase the plasticity of concrete and change the strength of concrete. But do you know how it can change the strength of concrete?…
This article introduces how to make foam cement and how to choose materials including cement and foaming agent.…
Nano thermal insulation coating can be used to absorb ultraviolet rays in sunlight and is often used in current decoration buildings.…
This year, the U.S. steel market has undergone tremendous changes and prices have skyrocketed. As one of the most important commodities in the United States, steel is widely used in construction, bridges, automobiles and even spoons. The increase in…
