PROCESS FOR PARTIAL REPLACEMENT OF NATURAL SAND BY WASTE MATERIALS USED AS ARTIFICIAL SAND

摘要

Due to heavy demand of river sand which is used as fine aggregate for making concrete becomes scarier and poses environmental problems which forces to find suitable substitute. Use of waste material as partial replacement to natural sand is the cheapest and easy way of getting substitute for natural sand. There is a large variation in the strength of concrete due to variation in concrete mix. Concrete mixes are design for various % increments of waste materials as partial replacement of natural sand. Compressive and tensile test are conducted to study the strength of concrete for above replacement. Following invention is described in detail with the help of Figure 1 of sheet 1 showing the moulds used for specimen casting and Figure 2 of sheet 2 showing immersion curing process.
