The influence of water consumption is very obvious. In the actual application of concrete engineering, sometimes if the water consumption is increased by more 1~3kg/m3, the concrete will appear serious bleeding phenomenon, which will cause defects su…
Polycarboxylate superplasticizer plays four main roles in concrete mixture. Firstly, in order to improve the pouring performance of concrete, the workability of concrete is improved without changing the composition of concrete.…
Polycarboxylate superplasticizer is the latest generation of high-performance superplasticizer.…
Polycarboxylate superplasticizer has more advantages than traditional naphthalene series and aliphatic superplasticizers when mixing high-strength concrete, but for low-strength concrete whose strength is not greater than C30, its high water-reducing…
In terms of the adaptability of cement and concrete superplasticizer, the type and quality of concrete superplasticizer also play an important role. Therefore, concrete superplasticizers should be selected according to the adaptability to cement and…
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…
