Abstract. This research was conducted with the use of recycled aggregate as modification. In terms of the use of recycled aggregate, the percentage of recycled aggregate should be determined because the strength of concrete would not be obtained by the high percentage of recycled aggregate.The scope of study is about comparison between recycle coarse aggregate and natural aggregate in terms of

Influence of bonded mortar of recycled concrete aggregates

10/07/2019 Recycled coarse aggregate (RCA) has about 28% higher bonded mortar content (BMC) with porosity of bonded mortar (BM) almost double as that of recycled fine aggregate (RFA). This leads to inferior interface between aggregate and cement paste thereby affecting the overall concrete properties. It is suggested to use pre-treatment methods for

A Study of Concrete Made with Fine and Coarse Aggregates

Both coarse and fine recycled aggregates decrease the compressive strength. Typical results for the relationship between compressive strength and curing time are presented in Figure 2. The results concern mixes with RFA. All the tested mixes present a decrease in strength. This is mainly due to the added water for the work ability correction. However, the compressive strength of young concrete
