Foam concrete for low load bearing structures and its properties

Abstract

This study examines lightweight foam concrete compressive strength and workability by incorporating industrial waste material (Fly-ash, GGBS, Silica-fume) in different percentages. By using this surplus material, the strength of concrete increases steadily as compared to previous research papers. Rapid growth for heavy construction in the modern world leads to the development of innovative technologies in the construction sector, mainly in the production of stronger, lighter and smarter concrete. The density of light weight foam concrete generally varies from 400-1800 Kg/m3; these contribute for low strength capacity of building, roofs filling, wall filling, panels, bridge abutments, ground stabilization, tunnel infill, subway infill, stabilization of road foundation and light weight blocks. Quality of Foam concrete plays a vital role in compressive strength of concrete we used synthetic foam it was easily available outside. As per (IS CODE – 2185 PART-4) the standard size of light weight concrete bricks Length: 400,500 (or) 600mm. Height: 200,250 (or) 300mm. Width: 100, 150 (or) 200mm. Thermal conductivity:0.32-0.54W/mk. Sound insulation: 37-42db. But we done experimental on the cubes which are available in our college 150x150x150mm is done. Foam light weight concrete of low density the water resistance will be less and it float in water. We can reduce the overall cost of the construction project. The foam generated by using foam generator and due to this foaming agent, the concrete is light weight and instead of coarse and aggregate we use fine aggregate material. The study was planned to produce 1600 Kg/m3. The confirmation of the workability, strength and plasticity of the foam concrete by measuring the coated cubes after 7, 14 and 28 days of curing. This test was intended for a thickness of 1600 kg/m3. This test was obtained to ensure the workability, plastic thickness and compressive strength of foam concrete. Samples were made and tested at the age of 7,14 years and 28 days.
