2022-1-7u2002·u2002Polyacrylamide in Cement Concrete Modification - CHINAFLOC. Due to cement concrete mixer speed is slow compared with net cement slurry mixer (cement concrete mixer speed for 42 r.m in, net and cement slurry mixer speed from 140 to r.m in + - 5 r.m, in high speed since to 285 r.m in plus or minus 10 r.m in), so the mixing shear rate is low, with the benchmark …
