摘要

本文对混凝土中骨料和水泥的替代材料的可能性进行了研究和报道。采用未经处理的再生粗骨料(URCA)和处理过的再生粗骨料(TRCA)配制混凝土混合料，分别配制无渣(mix I)和含渣(mix II)两组混合料。将再生骨料用不同摩尔浓度(0.1M、0.3M和0.5M)的盐酸(HCl)处理后，作为混凝土中原始骨料的替代材料。通过标准试验对混凝土力学性能、耐久性和混凝土形态进行了检测和分析。在两个混合组中，TRCA混合组的所有特征都比URCA混合组有显著改善。在两种配合组中，掺渣混凝土(mix II)比不掺渣混凝土(mix I)表现出更好的耐久性特性。混凝土中TRCA和矿渣的结合从各方面都大大提高了混凝土的性能。

Properties of concrete having treated recycled coarse aggregate and slag

The possibility of using substitute materials for aggregates and cement in concrete were studied and reported in this paper. Concrete mixtures with untreated recycled coarse aggregates (URCA) and treated recycled coarse aggregates (TRCA) were used to prepare two mix groups of without slag (Mix I) and with slag (Mix II). The recycled aggregates were treated with hydrochloric acid (HCl) having different molarities (0.1M, 0.3M and 0.5M) before used as a substitute material for virgin aggregate in concrete. The concrete mechanical, durability properties and morphology of concrete were examined through standard experiments and analysed. In both mix groups considerable improvement in all characteristics were identified in TRCA mixes than URCA mixes. Among the two mix groups the concrete mix with slag (Mix II) showed better durability characteristics than mix without slag (Mix I). The combination of TRCA and slag in concrete substantially increases the characteristics of concrete in all means.

期刊介绍： The Journal of Construction is aimed at professionals, constructors, academics, researchers, companies, architects, engineers, and anyone who wishes to expand and update their knowledge about construction. We therefore invite all researchers, academics, and professionals to send their contributions for assessment and possible publication in this journal. The publications are free of publication charges. OBJECTIVES The objectives of the Journal of Construction are: 1. To disseminate new knowledge in all areas related to construction (Building, Civil Works, Materials, Business, Education, etc.). 2. To provide professionals in the area with material for discussion to refresh and update their knowledge. 3. To disseminate new applied technologies in construction nationally and internationally. 4. To provide national and foreign academics with an internationally endorsed medium in which to share their knowledge and debate the topics raised.
