随着再生骨料制造工艺的提高，再生骨料的质量应足以用于结构混凝土。本研究表征了使用再生粗骨料和细骨料的混凝土的抗压强度和弹性模量。强度试验前，对再生骨料的基本特性进行了初步分析，再生骨料满足KS F 2573中的1级要求。随着替代率的增加，再生骨料混凝土的抗压强度和弹性模量下降。当粗骨料和细骨料完全被再生料替代时，抗压强度和弹性模量分别下降13%和31%。根据测试结果，本研究提出了预测再生骨料混凝土的抗压强度和弹性模量相对于替代率的方程。方程中的值与本研究和其他研究的测试数据非常一致。
As a manufacturing process of recycled aggregate improves the quality of recycled aggregate shall be sufficient enough to be used for structural concrete. This study characterized compressive strength and elastic modulus of concrete that used recycled coarse and fine aggregate. Before the strength tests, the fundamental characteristics of recycled aggregate were preliminarily analyzed and the recycled aggregate satisfied the class 1 requirements in KS F 2573. As the replacement ratio increased, the compressive strength and elastic modulus of recycled aggregate concrete decreased. When the coarse and fine aggregates were completely replaced with the recycled, the compressive strength and elastic modulus were decreased by 13% and 31%, respectively. Based on the test results, this study suggests equations for predicting the compressive strength and elastic modulus of the recycled aggregate concrete with respect to the replacement ratio. The values from the equations were in good agreement with the test data from this study and others.
