Assessment of Flexural Strength of Mortar Containing Brick Dust and Saw Dust as Partial Replacement of Fine Aggregates

The researchers are doing great efforts to find the replacement of sand in both concrete as well as mortar, they are finding ways to use by-products or waste product. The use of concrete and mortar involves the consumption of a natural resource that too only non-renewable resource except water. The focus of this study is that the use of two waste/byproducts as the partial replacement of sand in mortar. In the present study, the mixture is taken as (1:3). The partial replacement of sand is done in three different percentages (10%,20%,30%). In the first mix, 10% of sand is replaced with 5% each of sawdust and brick dust. Similarly, in the next two mixes, 20% and 30% of sand are replaced. For all the mix flexural strength test is carried out at 7, 14 and 28 days. Flexural strength increases to 20% and decreases afterwards. Higher flexural strength is at a 10% replacement of sand.
