查询词典 rust cement

Optimal mixing ratio of SRA as delay forming agent in cement treated base is 0.05%-0.06%; the influence of compacting delay on strength and dry density of road base may be reduced by SRA additive, forming time may be delayed to 9h; after the forming time is delayed to 4h, 6h and 9h, the strength and dry density shrinkage of cement-treated base with SRA admixture are much less than that of those without SRA.

SRA用作水泥稳定粒料路面基层的延迟成型剂的最佳掺量在0.05％～0.06％：用SRA可降低因延迟压实对水泥稳定粒料基层的强度和干密度的影响，可把延迟成型时间延长到9h；在成型延迟4h，6h，9h后，掺入SRA的水泥稳定粒料的强度和干容度损失明显小于未掺外加剂的混合料在相同延迟成型务件下的强度损失。
