water reducer cement admixtures pce based superplasticizer

The research never stops   After the first generation of water reducing agents represented by ordinary water reducing agents of llsulfonate series and the second generation of water reducing agents represented by naphthalene series highly effective water reducing agents, polycarboxylic acid water reducing agents are the third generation water reducing agents, which are characterized by their low content (solid content about 0.20%) and high water reducing rate (not less than 25%). Even up to 35%), the enhancement effect is good (28d compressive strength ratio is not less than 30%), the amount of concrete shrinkage increase is less (28d shrinkage ratio is not more than 110%), the production process does not use formaldehyde and other biologically harmful raw materials, flexible design of molecular structure, Therefore, it is hoped to synthesize and issue water-reducing agent products with different functions such as slow release, slump retention, viscosity reduction, and low bleed a…
