Estimation of Conventional Pcc Strength And Durability with Partial Replacement of Cement using Aluminium Powder and Rice Husk Ash

Abstract

Bond is generally noted to be most costly constituents of cement. The whole development industry is looking for an appropriate and viable the waste item that would extensively limit the utilization of concretes and at last lessens the development cost. Rice husk slag (RHA) which has the pozzolanic properties is a route forward. A relative report on impacts of solid properties when OPC of differing evaluations was mostly supplanted by RHA is examined in this paper. Rate supplanting of OPC with RHA was 0, 10, 20, 30 and 40% individually. The compressive quality, water ingestion, shrinkage and solidness of cement were for the most part considered. The examination recommends that up to 20% supplanting of OPC with RHA can possibly be utilized as halfway concrete substitution, having great compressive quality execution and durability. Percentage supplanting of OPC with Aluminum powder (Al) is 0.5% which is kept steady. We are utilizing M sand rather than typical sand to diminish the expense of development and builds quality and sturdiness concrete. The examination proposes the supplanting of concrete with RHA and Aluminum powder expands the compressive quality, solidness, and diminishes the expense of development.

Evaluation of properties of fibre reinforced asphalt mix with copper slag as the filler

“…The copper slag-contained asphalt mix has a high resistance to moisture and medium-to-long-term ageing [15]. The indirect tensile strength and resiliente modulus get increased for different temperatures (25 °C, 35 °C, 45 °C, 55 °C, and 60 °C) for the copper slag-contained asphalt mix when compared to the conventional asphalt mix [16]. From SEM analysis, it was found that there was no difference between the copper slag-incorporated asphalt mix and conventional asphalt mix [17].…”
