UPV CHARACTERISTICS AND DURABILITY ASPECTS OF THE COCONUT SHELL ASH CONCRETE

Researchers from all over the world are finding new ways and new materials to replace the cement constituents. In this paper cement in mortar was replaced by 10%, 15%, 20%, 30%, 40% 50% and 60% with coconut shell ash (CSA). Durability of mortar was found out for NaCl, MgSO4 and saline marine or marshy water. To assess the resistance for the temperature change wet and dry cycle test were also performed on the CSA mortar. Change in weight and strength of the samples were found before and after conducting the test. Ultra sonic pulse velocity test were also conducted to find out the quality of the concrete samples prepared with coconut shell ash (CSA).It is found that the samples shows good resistance in different durability test and UPV test also shows that the samples are homogenous and compact. Coconut shell ash may be considered as suitable replacement of cement up to 10% as far as durability is concerned.
