In this paper presents the mechanical and microstructure of Effect of agro waste ashes on the properties of recycled coarse aggregate concrete incorporating rice straw ash and cotton stalk ashes as a replacement ratio by the weight of cement content , Recycled coarse aggregates were replaced by the ratio(RCA) by the weight of natural coarse aggregates. Seven mortar mixes are prepared with Rice straw ash (RSA) and cotton stalk ash(CSA). Three mixes are used with 5%,10% and 15% RSA and remaining Three mixes are used with 5%,10% and 15% of CSA. These seven mixes are casted for 28 days compressive test is conducted and we get high performed percentage mixes are CSA 10% and RSA 5%. The recycled coarse aggregates (RCA) is used as a replacement of normal weight coarse aggregates with a ratio of 70%.

Recycled coarse aggregates (RCA),Rice straw ash (RSA),Cotton stalk ash (CSA),concrete, mechanical properties and durability properties.
