POLLUTION FREE GEOPOLYMER CONCRETE WITH M- SAND

M. I. ABDUL ALEEM AND PD. ARUMAIRAJ

Abstract

Geopolymer concrete is the concrete made without using any quantity of cement. Instead the waste material from the thermal power station called Fly Ash is used as the binding material. This fly ash reacts with alkaline solution like Sodium Hydroxide (NaOH) and Sodium Silicate (Nal,Si0) and forms a gel which binds the fine and coarse aggregates. Similarly another Artificial material called Manufactured Sand (M-Sand) is also used as the fine aggregate against the normal river sand. Concrete cubes of size 100 x 100 x 100 mm, Cylinder specimen of size 150 mm diameter and 300 mm height and Prism specimen of size 100 x100 x 400 mm were prepared for both the Geopolymer Concrete with M-sand and conventional ordinary Portland cement concrete, for the same mix. The Cube compressive strength, Split Tensile Strength, Cylinder Compression and Prism Beam Flexure Tests were found out at 7, 14,21and 28 days. The strength of Geopolymer Concrete is compared with normal cement concrete and found the strength of Geopolymer concrete with M-sand is high. Hence, pollution free Geopolymer concrete with M-sand can be an alternative to ordinary Portland cement concrete.
