【摘要】 旨在研究未掺任何外加剂的再生混凝土的抗冻性能,即再生混凝土在硬化初期受到一次冻结对其质量的影响,用抗压强度来表征它的力学性能。同时研究经过在标准条件下养护几天后再受冻的再生混凝土的早期抗冻能力,并分析影响再生混凝土抗冻性能的原因。更多还原

【Abstract】 The article aims to study the freezing resistance ability of the recycled concrete without any admixture and the effect on the quality when it was frozen in the early hardening age.Its mechanical capability is indicated by the compressive strength.In the same time,it studies the early freezing resistance after curing several days in standard conditions.Then the reason that influences the strength development of the concrete is analyzed.更多还原
