为了研究掺加建筑垃圾细骨料的再生混凝土路面材料吸水率与吸水前后抗压强度,文章以再生细骨料取代率、水灰比、骨灰比为变化参数,采用正交试验方法设计了54个试块,基于试验数据,分析了各因素对再生混凝土吸水率及吸水前后抗压强度的影响。研究结果表明:水灰比是影响干燥状态及吸水饱和状态抗压强度的主要因素,而骨料取代率是影响吸水率的主要因素。
In order to study the water absorption rate and compressive strength before and after water absorption of the recycled concrete pavement with the fine aggregate of construction rubbish, the orthogonal design was adopted in this paper based on the parameters of the recycled fine aggregate substitution ratio, the water-cement ratio and the ashes ratio Based on the experimental data, the influence of various factors on the water absorption of recycled concrete and the compressive strength before and after water absorption were analyzed. The results show that the water-cement ratio is the main factor that affects the compressive strength in the dry state and the saturated water-saturated state, while the aggregate substitution rate is the main factor affecting the water absorption.
