A Study of relation between strength activity index and cement equivalence factor of biomass ash

Abstract

This research aims to study the relationship between the strength activity index and cement equivalence factor of biomass ash cement. The strength activity index is collected by using the mechanical test method which also used as a measurement to test the ability of pozzolanic reactions. Whilst, the effectiveness of cement equivalent is commonly used in the concrete mixed with fly ash design regarding to the British Standards. These values are used to measure the unit weight of the pozzolan which is effective against  unit of cement. The cement equivalent effectiveness is difficulty to testing and have to use a large amount of the sample tests. This research has shown the correlation between the two variables to demonstrate the ability of biomass ash as raw material to produce pozzolannic. The finding will enhance the efficiency of mortar and concrete using in the future. The results shows that it has a direct relationship between strength activity index and cement equivalence factor with a compressive strength of mortar and concrete. The Strength activity index test is popularly used to test the ability of the pozzolanic reaction since it’s convenient and obvious. It can be clearly seen from the tests that the liable of relationship between strength activity index and cement equivalence factor of biomass ash are tending in the same direction.
