摘要
研究了负温高强泵送混凝土的负温硬化限及其配合比的设计要点与方法，并确定出Ｃ５０～Ｃ６０级负温高强泵送混凝土强度试配公式及其防冻剂掺量值计算公式，可供施工单位进行高强泵送混凝土冬期施工时参考。
The harden boundary of high strength pumping concrete at minus- temperature(HSPCMT)and the design method of mix proportion are discussed.And then it is determined that the antifreezing admixture has a value of amount up to boundary in the concrete and sand proportion is limted when the concrete pumping and a test statistics strength formula is applicated.These parameters could be used in winter construction when construction units need high strength puming concrete.
