摘要
本文通过对高性能混凝土用水量及其影响因素的分析，提出用水量的最高限值。并指出在高性能混凝土组成材料中，高效能复合减水剂所担负的重要角色，其减水率及掺量将随着高性能混凝土强度等级的提高而提高。因此，建议施工单位根据所使用的外加剂品种及水泥品种，考虑影响用水量的诸因素，建立外加剂减水率与掺量的关系式，以指导施工。
In this paper,the maximum limit value is presen ted by bnalysis the consumption of water of HPC and those effect factors.The sup er-reducing-water compound is reputed an important role in compose material of HPC.When increased the strength of HPC,its reducing-water rate and admixed amo unt are raised.So,in order to instruct start construction,the construction units hould consider which kinds of effect factor of consumption of water on according to be used those variety of admixture and concrete,and make connection mood wit hreducing water ratio and admixed amount of admixture.
