Abstract :

The use of hypo sludge in concrete formulations as a supplementary cementatious material was tested as an alternative to traditional concrete. The cement has been replaced by hypo sludge accordingly in the range of 0%, 10%, 20%, 30% & 40% by weight for M–25 and M–40 mix. Concrete mixtures were produced, tested and compared in terms of compressive & flexural strength with the conventional concrete. These tests were carried out to evaluate the mechanical properties for up to 28 & 56 days. To improve the engineering properties viz. compressive strength 12mm KDM glass fie is use at rate of 0.56% by the volume of material. The test results for compressive strength up to 28 days & flexural strength for 56 days are taken. The use of glass fies has increased the compressive strength. Flexural strength using center point loading also meets the required parameters. In this study trial tests for concrete with 0.56 % glass fie and increasing% hypo sludge are conducted to indicate the differences in compressive strength and flexural strength by using cubes & beams.
