Today'' s concrete superplasticizers are primarily prepared by intensifying numerous materials such as polycarboxylate water-reducing mommy alcohol and polycarboxylate slump-preserving mommy alcohol plus retarders, air-entraining agents, and defoamin…
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.…
The impermeability of concrete is related to its porosity and pore structure.…
Polycarboxylate superplasticizer is based on unsaturated polymerizable monomers with active groups such as carboxyl group, sulfonic acid group, hydroxyl group and polyoxene group as raw materials.…
According to the different molecular structure, it can be divided into four generations of polycarboxylate series superplasticizer, the first generation is acrylic acid copolymer, the second generation is propylene ether type, the third generation is…
First of all, pay attention to the storage environment of polycarboxylate superplasticizer, try to store polycarboxylate superplasticizer in a cool, ventilated, no direct sunlight place.…
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.…
