polycarboxylate superplasticizer powder is a newly developed water-reducing agent that can lessen the cement to water ratio in concrete without negatively affecting the concrete’s function. It is widely used in the construction of bridges, highways, tunnels, dams and high rise apartments among other projects.
It is an environmental friendly product with the potential of lower concrete shrinkages, low dosage, good moisture retention, high performance and robust molecule structure and optimum production procedure. It is also non-toxic, non-polluting and does not use formaldehyde in the production process.
PCE powder can be applied to cement based and gypsum based self-leveling mortar, grouts, special early strength mortar, repair mortar, grouting agent etc. It can also be used as a dispersant for gypsum-based powder materials and refractories.
NS-doped PCE with better dispersion can be obtained by doping nano-silica onto PCE molecular chains. The resulting NS-doped polycarboxylate superplasticizer (NS/PCE) can be evenly dispersed in cementitious materials.
The sensitivity of conventional long-chain polyethylene glycol grafted PCE to clay impurities was elucidated in this study. The NS-doped PCE shows higher fluidity and iodine value than traditional long-chain polycarboxylate superplasticizer (PCE) when it is mixed with a cement paste with varying amounts of soluble clay impurities.
Moreover, the NS-doped PCE is resistant to alkali sulfates. In addition, it can be used to prepare high-strength, high-fluidity concrete and refractories with a low water content. It is especially suitable for concrete in a hot environment. It is also a good choice for green concrete.
