再生混凝土的配合比与抗压强度关系实验研究

The experimental studies on the relationship between mix proportion and compressive strength of Recycled Concrete

影响再生混凝土强度的因素较多,而且复杂,通过再生混凝土抗压强度实验,研究了再生混凝土抗压强度与水灰比以及再生粗骨料取代率之间的数理关系,提出了再生混凝土的强度设计公式与设计方法。

The experimental studies on compressive strength of Recycled Concrete（ RC） with different proportion of coarse aggregates and different water cement ration were carried out. Which discovered that there are a lot of factors may influence the compressive strength of RC. Two main factors-proportion of coarse aggregates and water cement ration were discussed. Mathematical relationship between the compressive strength and proportion of coarse aggregates,water cement ration were obtained after regression analysis. In the end,a group of design formulas on relationship between mix proportion and compressive strength of RC are proposed for engineering.
