摘要: 为提高固废在混凝土中的综合利用率,制备一种具备高效消纳固废能力的新型混凝土,通过原材料优选和L16(43)正交试验设计,采用极差分析和方差分析研究了橡胶颗粒(RP)取代砂、玻璃粉(GP)取代水泥、再生粗骨料(RCA)取代天然粗骨料(NCA)时,三者取代率对混凝土力学及抗冲击性能的影响,并采用Weibull分布模型对冲击试验结果进行拟合和失效概率预测。结果表明:各因素对混凝土力学性能影响的主次顺序为RP、RCA、GP,各因素对混凝土抗冲击性能影响的主次顺序为RP、GP、RCA;当RP掺量为20%(体积分数)时,与RP掺量为0%时相比,抗冲击性能提高81.8%,抗压强度和劈拉强度分别降低21.63%、12.65%;当GP掺量为10%(质量分数)时,与GP掺量为0%时相比,抗压强度、劈拉强度和抗冲击性能分别提高2.87%、2.35%、15.0%;当RCA掺量为70%(体积分数)时,与RCA掺量为0%时相比,抗压强度、劈拉强度和抗冲击性能分别降低11.01%、10.77%、10.5%。Weibull分布模型可准确描述橡胶玻璃粉再生混凝土试样的抗冲击次数的概率分布。

Abstract: In order to improve the comprehensive utilization rate of solid waste in concrete, a new type of concrete with high efficiency of solid waste absorption was prepared. Through the optimization of raw materials and L16 (43) orthogonal test design, the effects of rubber particles (RP) replacing sand, glass powder (GP) replacing cement and recycled coarse aggregate (RCA) replacing natural coarse aggregate (NCA) on the mechanical properties and impact resistance of concrete were studied by range analysis and variance analysis. The Weibull distribution model was used to fit the impact test results and predict the failure probability. The results show that the primary and secondary order of the effects of various factors on the mechanical properties of concrete is RP, RCA and GP, and the primary and secondary order of the effects of various factors on the impact resistance of concrete is RP, GP and RCA. When RP content is 20% (volume fraction), compared with the RP content of 0%, the impact resistance increases by 81.8%, and the compressive strength and splitting tensile strength reduce by 21.63% and 12.65%, respectively. When GP content is 10% (mass fraction), compared with the GP content of 0%, the compressive strength, splitting tensile strength and impact resistance increase by 2.87%, 2.35% and 15.0%, respectively. When RCA content is 70% (volume fraction), compared with the RCA content of 0%, the compressive strength, splitting tensile strength and impact resistance reduce by 11.01%, 10.77% and 10.5%, respectively. Weibull distribution model can accurately describe the probability distribution of impact resistance times of rubber glass powder recycled concrete samples.
