Flow, Strength and Hydration Heat Properties of Mortar using Industrial By-products

Abstract
This study conducted experiments to examine the flow, strength and hydration heat properties of mortar produced with industrial by-products. As the replacement ratios of industrial by-products increases, the flow increases. This is showed that the ball-bearing effect of fly ash caused an increase in rheological properties and that the amount of ground granulated blast furnace slag affected rheological properties. The results of compressive strength test showed that blended cements improved a long-term strength, but exhibited small early strength compared to that of an OPC mix. This can be traced to the delayed production of Ca(OH)2 during the hydration of C3S and C2S. In the case of a higher replacement ratios of industrial by-products, the mortar tend to produce less Ca(OH)2, resulting in less pozzolanic reaction and smaller final compressive strength.
