Abstract
The paper reports the mechanical and physical properties of new hydraulically bound cementitious materials made from environmentally friendly waste fly ash and chemical additives. The new products can be used for cement replacement material and need no burning process as the case with conventional cement manufacturing process. Two fly ashes generated from incineration of domestic and industrial wastes were blended and optimized to generate a new ternary blended cementitious material. The developed blended formulation showed versatility in terms of offering different grade mortar having properties like conventional cement. The early strength was comparable to the control mortar, but after the age of 14 days and in the new products, the crushing strength rate is higher than the crushing strength rate produced using ordinary Portland cement mortar. The influence of water content, alkali activation, synthesis by water dispersing agent has also been analyzed in addition to the new material compressive strength.
