Durability properties of concrete made from agricultural waste

Abstract

Concrete having waste materials as part of the ingredients in the matrix part is called green concrete as for as concrete technology concern generally. Being agricultural waste materials as one of the ingredients in the matrix part of concrete is specifically fulfills the meaning for green concrete from this research work technical information. Concrete developed with the agricultural waste by using scraped coconut shell shows better fresh concrete properties, hardened concrete properties and durability properties. In this research work the durability properties such as water absorption test, rapid chloride penetration (RCPT) test and sorptivity test were conducted for coconut shell aggregate concrete and compared with conventional granite aggregate concrete reasonably as per the recommended codel provisions for the three concrete mixes. From the experimental tests it is concluded that there is no considerable variations in the final result of coconut shell aggregate concrete when compared with conventional granite aggregate concrete. There is no any biological chemical decomposition in the coconut shell aggregate concrete when it is under the short term durability tests of maximum ninety days.
