| Abstract | ||
| Concrete components are considered as one of the most essential materials in buildings. The project’s cost is increasing due to the usage of these materials, hence natural resources are being employed to boost strength values while lowering construction costs. In the current study, the cement in concrete is partially replaced by rice husk ash due to its high amorphous silica and CaO content. The agricultural by product known as rice husk is collected. Both fresh and hardened concrete properties were studied by casting specimens with different proportions up to 20% rice husk ash replacement. According to the experimental results, the rice husk ash proportion in concrete should be increased from 0% up to 20% to achieve the highest values of mechanical properties. It was found that the best replacement proportion is 10% after 28 days of curing. | ||
