STRENGTH PROPERTIES ON FOAMED CONCRETE

Abstract

In order to cut down on building weight and expense, speed up the construction process, and make handling of precast segment easier, partition wall applications are suitable for the foamed concrete constructions. Compressive strength of foamed concrete of varying water cement ratio has been investigated. Compressive strength and split tensile strength is correlated in this paper's experimental study of  strength properties on foamed concrete with a density of 1200 kg/m³. At the age of 7 days and 28 days the compressive strength was measured and for 28 days the split tensile strength was measured in 66 foamed concrete cubes of varying densities and water-cement ratios. The spread value of the inverted slump and flow table was calculated. The greatest compressive strength of 9.2 MPa and split tensile strength of 3.4 MPa were reported in experiments conducted at a density of 1200 kg/m³ andfor the w/c ratio of 0.5. In this study, we tested foamed concrete with the usage of slag materials variation and w/c ratio of 0.4 and 0.5 respectively to measure its compressive strength and split tensile strength. Steel slag is used in place of sand, and the amounts used depend on the context.
