Management of concrete mobility preservationand regulation of concrete composition
It is established that the developed modifier SAS-3 maintains preserving of the mobility of concrete mixture for 3 hours or more. SAS-3 is a complex admixture and by carefully optimized mixing ratio is not very sensitive to the chemical and mineralogical composition of cement. Despite the slow start of structure, concrete with SAS-3 rapidly gaining strength in the subsequent periods of hardening. The addition provides a stable effect over a wide range of cement consumption (350-500 kg/m3) and at various initial mobility concrete mixture.
