塑性混凝土防渗墙配合比设计及在水利工程中的应用研究OA
Research on the Mix Design of Plastic Concrete Anti-seepage Wall and its Application in Hydraulic Engineering
文中基于某水利枢纽塑性混凝土防渗墙施工需求,以水泥掺量、膨润土掺量及砂率为参数进行塑性混凝土配合比设计研究,分析各参数对塑性混凝土流动性能、力学性能及抗渗性能的影响.结果表明,相同水胶比情况下,增加水泥掺量能够改善塑性混凝土的力学性能和抗渗性能,当水泥掺量由80 kg/m3 增加到200 kg/m3 时,塑性混凝土的抗压强度、弹性模量分别增大2.3、239 MPa,相对渗透系数减小0.411×10-7 cm/s;相同水泥掺量下,增加膨润土掺量能提…查看全部>>
Based on the construction requirements of a certain water conservancy hub's plastic concrete anti-seepage wall,a study was conduc-ted on the mix design of plastic concrete using cement content,bentonite content,and sand ratio as parameters.The influence of each parame-ter on the flow performance,mechanical properties,and anti-seepage performance of plastic concrete was analyzed.The results show that in-creasing the cement content can improve the mechanical a…查看全部>>
