| Abstract | ||
| Reuse of Construction waste gives two aims, the first is to remove large quantities of pollution resulted from these waste, the second provides cheap resources for concrete aggregates. The current study includes testing many properties of concrete mix with local waste concrete as coarse aggregate, after removing coarse gravel , which means using mortar of this waste concrete after crushing, grading and washing. Results show that this recycled aggregate has lower specific gravity and absorption compared with natural aggregate used in Iraq, also results show that the concrete prepared from this recycled aggregate has acceptable compressive strength and absorption and it has good flexural strength and low dry density as compared with concrete with local natural aggregate. this concrete is suitable for paving and blocks making. | ||
