摘要
进行了掺超细矿渣的胶材净浆与水泥净浆及掺超细矿渣的高性能混凝土与普通混凝土体积稳定性的对比试验 ,找出了它们的体积线性变化规律 ,高性能混凝土早期有较大的自收缩和干缩 ,其中自收缩占主要地位 ,收缩稳定期短 。
Research on the volume stability by a series of contrastive experiments between pure gel by mixing super fine slag and grout and beween high performance concrete(HPC) and ordinary concrete was carried out.The linear volume charge law was found out there exists more autogenous shrinkage which is the main part of shrinkage and dry shrinkage at early stage in HPC than the ordinary concrete and to HPC,the stable shrinkage time is shorter and shrinkage at later time is smaller than the ordinary concrete.
