Mechanical and Thermal Evaluation of Partial Replacement Cement Mortar with Incorporation of Parali Straw Ash

The main aim of this experimental article is to provide comprehensive knowledge about alternative cementous material. Replacing cement in an appropriate ratio leads to a reduction in carbon emissions. PSA or Parali Straw Ash is used as a partial cement replacement material with varying percentages from zero (controlled) to 10%, 20%, 30%, 40%, and 50% by weight of cement, respectively. The present investigation aimed to examine the potential of PSA as a material for partial replacement of cement, with a focus on assessing its influence on the mechanical, physical, and thermal characteristics of mortar. The results of the study indicate that the incorporation of PSA in mortar can be a viable alternative, as it demonstrates satisfactory performance when replacing up to 30% of cement content, without any detrimental effects on the overall integrity of the mortar. PSA is an excellent thermal insulator due to its low electrical conductivity.
