Slow-setting grinding aid
The invention relates to the technical field of cement admixture, and especially relates to a slow-setting grinding aid, which comprises the following raw materials by weight percentage: 10-25% of alcamines compound, 12-17% of propylene glycol, 10-18% of papermaking waste liquid, 8-14% of sugar refinery waste liquid, 0.02-0.05% of cellulose water retention material, 0.1-0.5% of calcium gluconate, 0.02-0.06% of sodium dodecyl benzene sulfonate and balance of water. The grinding aid has good slow setting effect, increase intensity at early and later phases of cement, guarantee cement quality, and has good plasticity-maintaining effect and low cost. The grinding aid can be used in concrete constructed under hot climate, large volume concrete and cement concrete requiring long time storage or long distance transport.
