Application of Polycarboxylate Superplasticizer in Concrete

Polycarboxylate superplasticizer is used in medium and low strength concrete. Compared with naphthalene superplasticizer and its compound products, which are the most widely used in the market at present, polycarboxylate superplasticizer has better construction workability, stronger slump resistance, smaller concrete shrinkage, and can effectively alleviate the initial cement hydration heat, control temperature cracks and enhance the compressive strength ratio of concrete, is the current commodity concrete market naphthalene, fat family (retarder) superplasticizer, pumping agent ideal alternative products.
    Polycarboxylate superplasticizerOn the basis of improving the construction workability of fresh concrete, it can effectively reduce the shrinkage of hardened concrete, increase the volume stability and durability of concrete structures, realize the high performance of low-grade ordinary commercial concrete, improve the cohesion and plasticity of concrete, especially effectively avoid bleeding and segregation, greatly improve the workability of fresh concrete, and improve the construction performance of concrete pumping. If it is used in combination with fly ash, ground slag and other admixtures, it can prevent and control temperature cracks in mass concrete, prevent shrinkage cracks, improve engineering quality, improve the pore structure of concrete, greatly improve the durability indicators of concrete such as impermeability, carbonization resistance, dry-wet cycle resistance and freeze-thaw cycle resistance, and to some extent realize the high performance of ordinary concrete.
The powder polycarboxylate superplasticizer developed by Xindadi Group is dry and sprayed into powder on the basis of liquid superplasticizer, which is antifreeze in winter and anticorrosive in summer, and is convenient to transport, especially providing a better choice for long-distance transportation.
