Abstract: | As a developing country, construction is the one of main incomes producing in Malaysia. Huge amount of demolition waste were produced from these activities. In Malaysia, the construction waste has cause a significant impact on the environmental and also increasing trend. These demolition wastes are disposal illegally or disposed at landfill. This research to identify and compared the properties of natural coarse aggregate (NCA) and recycled coarse aggregate (RCA). Three mixes of concrete with target compressive cube strength ranging at 20 MPa were cast using recycled aggregate (RA) and one mixed for natural aggregate (NA). For this study, the percentage of RCA in concrete mix is 50%, 70% and 100%. To get the different of both aggregates, analysis such as particle size analysis, slump test, water absorption and compressive strength are provided. From the results shown that concrete mix NA have more strength than RA, water absorption of RA higher than NA, workability of NA higher than RA and lastly water absorption of RA higher than NA. For conclusion in this research based on the results from analysis, the percentages of RA suitable to use in concrete mix are 70% and fulfil the standard in concrete. |
