不同冷却制度下普强高性能混凝土的残余力学性能与渗透性的探讨

文章主要研究普强高性能混凝土在不同冷却制度下的残余力学性能和渗透性能。试件在经过200℃、400℃、600℃高温后,采用自然冷却（NC）和泡水冷却（QC）的方法使之冷却到常温。通过抗压强度试验、劈拉强度试验、表层渗透试验测试混凝土残余力学性能与渗透性。

Explorations on residual compressive strength and permeability of NS/HPC in different temperatures

An experimental investigation was conducted on residual mechanical properties and permeability of normal - strength high- performance concrete（NS/ HPC） exposed to elevated temperatures from 200 to 600℃ .Two cooling regimes were used including natural cooling （NC）and quench cooling in water（QC） , The residual mechanical experimentations include the compressive strength and the tensile splitting strength, The permeability expermentafion is the near- surface permeability .
