Influences of molecular weigh of main chain, length of side chain and degree of sulphonation on properties of water-reducer were discussed. Structure of water-reducer was characterized by IR and GPC. Influences of the reducer on fluidity of cement paste and water-reducing rate of concrete were investigated. Experimental tests showed that the high range water-reducer had an excellent dispersing ability for the cement particles and the water-reducing rate of concrete was higher than 30%.Read More
