| description | The research relied on taking five samples: The first sample is the Iraqi Ordinary Portland Cement. Physical tests were carried out for the purpose of comparison with other samples, as the rank of the Ordinary Portland Cement sample under study was 52.5R, according to the Iraqi specification No. 5, 2019. The second sample is concrete waste that was crushed then added water to it in known proportions according to the Iraqi specification and making a paste for concrete wastes only, but it failed to compressive strength and soundness. Three other samples of concrete waste 25%, 30%, and 35% with Ordinary Portland Cement as the addition of concrete wastes, were a partial substitute for the Ordinary Portland Cement. The results of the physical tests including fineness, setting time soundness, and compressive strength that were conducted on the third and fourth samples 25% and 30% were good results within the Iraqi specification No. 5, 2019. The result of physical tests at 35% of concrete wastes failed to test compressive strength. The results of mixing the concrete wastes with the Ordinary Portland Cement under consideration, showed that they can be mixed in various ratios and obtain different results. The more the concrete wastes mixed with the cement, the less the quality of the mixed cement was reaching the highest ratio that led to the failure of the mixture with the concrete wastes in terms of the physical properties. Basically, the mixture ratio of concrete wastes with the cement depends on the quality of the cement and its class in accordance with the compressive strength, and concrete waste quality. |
