The Influence Of Burning Temperatures and Percentage Inclusion of Microwave Incinerated Rice Husk Ash (MIRHA) On Normal Strength Concrete
This paper presents a laboratory study on the effect of microwave incinerated rice husk ash(MIRHA), burnt at different burning temperatures on the compressive strength of concrete. The performance of concrete mixes was determined by compressive strength test at ages 3, 7 and 28 days. The test result...

| Summary: | This paper presents a laboratory study on the effect of microwave incinerated rice husk ash(MIRHA), burnt at different burning temperatures on the compressive strength of concrete. The performance of concrete mixes was determined by compressive strength test at ages 3, 7 and 28 days. The test results, showed that 5% replacement of MIRHA with 800°C burning temperature provided good acceleration in compressive strength development in concrete. It was also shown that the inclusion of 10% replacement of MIRHA with 700ºC burning temperature improved the strength of concrete. MIRHA with burning temperature 600°C also revealed that the optimum replacement of MIRHA was 5%. The results were compared to the normal concrete without MIRHA. |
