Experimental Study on concrete behaviour with Partial Replacement of M-Sand with Unexpanded Perlite

Traditionally, river sand was utilized as fine aggregate in concrete manufacturing. However, due to the ongoing extraction of natural sand, its availability has become limited. Construction businesses have begun explore for alternative sustainable resources use aggregate. Manufactured (M- sand), recycled aggregate, crushed granite, rice husk ash, fly and other materials can cause dumpsite environmental contamination. These are viable substitutes Unexpanded perlite is also one such material which be used a replacement Perlite form volcanic glass resulted from cooled lava. This paper presents utilization M-Sand with partial unexpanded In present research, effect M- studied determine mechanical properties compressive strength at 7 days, 14 days 28 split tensile 28days flexural days. range 62%, 60%, 58%, 56%, 54%, 52% 50% UP percentage 38%, 40%, 42%, 44%, 46%, 48% respectively. The withstand 1.5 times thermal resistivity when compared conventional concrete.
