Abstract
The mortar mix is widely used material in the field of construction, due to its durability, strength and its usage for masonry and plastering to make the structure safe from weathering action to beautify the aesthetic view of the structure. Presently mortar is considered as an omnipresent because of its usage for finishing work in structures. It is a combination of cement, fine aggregate and water. In this combination, cement is the fixing material for the aggregate. The aim to this research was to analyze the behavior of normal cement mortar made with blended RHA and WGP of different mixes prepared at 10% of RHA and 5%, 10%, 15% and 20% of WGP and obtained the results of the various fresh and hardened properties. Five types of mixes were made by replcing RHA at 10% and WGP at interval of 5%. The replacement levels of OPC by RHA is fixed at 10%, however, WGP is replaced with varying dosage of 5%, 10%, 15% and 20% by the weight of cement. A nominal mix proportion of 1:3 at wc ratio of 0.50 was used for all mixes and specimens were tested at age of 3, 7 and 28 days. 45 cubes of 50mm x 50mm x 50mm were caste for compressive strength at 3, 7 and 28 days respectively. It was deducted from the research that the increasing dosage of RHA was reducing the flowability of concrete. The compressive strength of mortar cubes increased, by replacing RHA by 10% and WGP by 5%. Maximum compressive strength with inclusion of RHA and WGP was achieved at 10% RHA and 5% replacement of cement with WGP i.e. 19.89 MPa, 25.80 MPa and 31.76 MPa at 3, 7 and 28 days respectively. It is concluded from conducted parameters that 10% RHA and 5% replacement of cement with WGP is optimum.Keywords: Cement Mortar, Rice Husk Ash, Waste Glass powder, Flowability, Compressive Strength.
