查询词典 rust cement

Calcium lignosulphonate would reduce drying shrinkage, the influence of superplasticizer on drying shrinkage is related strongly to the water cement ratio of mortar. When the water cement ratio is lower (0.3 or 0.4), superplasticizer would increase drying shrinkage, which increases with water cement ratio decrease.
