摘要
随着铁路客运专线的建设,耐久性混凝土技术大规模得到了应用。本文通过试验研究揭示了一些影响混凝土收缩的因素;研究了细骨料细度模数、配合比砂率以及混凝土掺和料比例对混凝土收缩的影响规律;对于高强度、大体积混凝土的自收缩规律进行了研究。根据试验结果分析,结合笔者的实践生产经验,提出几点抑制耐久性混凝土收缩变形引起的危害的措施。
As the building ot Railway Passenger Line,technology of durability--concrete has been large--scale applied. In this paper, some factors that affecting the shrinkage of concrete are revealed through tests, and influences of Fineness modulus of fine ag- gregate, sand mix ratio and admixture ratio to concrete are also studied here. Besides, self--contraction law of large volume concrete with high strength is also studied. According to the trial results, and combining the author＇s practice of production experience, some suggestions are given in order to suppress the shrinkage deformation of the durability--concrete.
