摘要: 本研究采用100%再生细骨料和再生粗骨料配制全再生骨料混凝土，以最大程度利用废旧混凝土再生骨料并取得最佳经济效益。考虑再生骨料预湿处理并变换水灰比和水泥强度进行配合比设计，进行了全再生骨料混凝土工作性能和抗压强度、抗拉强度发展规律的试验研究。结果表明：通过合理的配合比设计和再生骨料预湿处理，全再生骨料混凝土的工作性能和抗压强度均达到设计要求；抗压和抗拉强度的发展几乎在养护龄期56 d之内完成，且抗拉强度的增长低于抗压强度。
Abstract: This study aims to research and develop a full-recycled-aggregate concrete (aRAC) made of 100% fine and coarse recycled aggregates to get the best benefits by reusing the waste concrete products at the most extent. By changing water-cement ratio and cement strength in mix proportion design of aRAC and the recycled aggregates dealt with pre-wetted process, tests were carried out to study the workability of fresh aRAC and the developments of compressive and tensile strengths of aRAC. Results show that by using proper mix proportion and prewetted recycled aggregates, the workability and compressive strength reached the targets, the development of compressive and tensile strengths was almost finished within 56 days, and the increment of tensile strength was lower relating to that of compressive strength at the same curing age.
