Experimental investigations on foamed concrete

Abstract

This study's objective was to assess the mechanical properties of pervious concrete, normal concrete, and foamed concrete, and examine the effects of various fibre kinds on the mechanical characteristics of foamed concrete, to identify the most effective types of fibers and optimal fiber percentages to use in foamed concrete mixtures. The study used a mix design approach to create different concrete samples, including foamed concrete, pervious concrete, and normal concrete with varying compressive strengths. The samples then underwent a series of tests to measure their density, compressive strength, tensile strength, and flexural strength. The study used various types of fibers, including brass-coated and crimped steel fibers and polypropylene fibers, at different percentages by volume and lengths to create different samples of foamed concrete. The samples then underwent various mechanical tests, including compressive, flexural, and split-tensile strength tests, to assess the effect of fibre addition on the foamed concrete's mechanical characteristics.
