Mechanical properties of roller compacted concrete containing recycled concrete aggregate
The compressive strength, splitting tensile strength, pulse velocity, and drop weight impact resistance of roller-compacted concrete (RCC) mixtures containing recycled concrete aggregate (RCA) were investigated. The cement contents of the RCC mixtures were chosen as 150, 200 and 250 kg/m3. In addition to the control mixtures containing no RCA, 25, 50, 75, and 100 wt% of the crushed limestone aggregate was replaced with RCA. In this way, 15 RCC mixtures were prepared. The water content of RCC mixtures was determined by the maximum density method. The results showed that increasing the amount of recycled aggregate decreased the mechanical properties of the concrete. However, up to 25% replacement level, recycled aggregate had not a significant detrimental effect on the properties of RCC. Besides, the detrimental effect of RCA substitution was more pronounced in leaner mixtures and reduced by increasing the cement content of the RCC.
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.
