As a synthetic polycarboxylic acid high slump retaining water reducer, it has strong ability to maintain the dispersion of cement particl s The product has good adaptability to cement and high retention rate of double bond, which greatly improves the reaction activity of the product, so as to improve the utilization rate of the product and finally reduce the production cost of water reducing agent. 1.1% F-108(22%)is added in concrete,water reducing rate is above 30%. Improving early strength&strength after 28days Compressive strength 1day 180 3days 170 7days 160 28days 150. Greatly reducing W/B ratio,shrinkage and creep,improving durability. Low slump loss,slump retention index â?¥ 190mm. Complying with ISO14001:2004 certi
ation,content of chloride ion 0.1%.
