Technical and economic effects of high-performance concrete water-reducing agents

① When the water consumption remains unchanged, the slump of concrete can increase by 10 to 20cm;

② Keeping the workability of concrete unchanged, water can be reduced by 10% to 50%, and the strength of concrete It can be increased by 15% to 20%, especially the improvement in early strength is more significant;

③When the strength of concrete is kept unchanged, the cement consumption can be saved by 10% to 15%;

④ The heat release rate of cement hydration slows down and the heat release peak is delayed;

⑤ The phenomenon of concrete bleeding and segregation is greatly improved;

⑥ The water permeability of concrete can be reduced by 40% ~80%, improving the ability to resist permeability, frost resistance, chemical corrosion and rust;

⑦Special concrete can be formulated, which will be more economical, simple and flexible than using special cement.
