Effect of Air Entrainment on the Properties of Concrete Structures Using Hydrogen per Oxide as an Admixture

Abstract

Abstract: Air entrained concrete can be produced by introducing suitable air-entraining agent, one such commonly available material in India is hydrogen peroxide which is being used in my experimental work. The primary objective of this study to find the appropriate amount of hydrogen peroxide (3%) for strength and density, water absorption, other properties of concrete. For which the amount of H2O2 is varied from 0 %, 2.5%, 5%, and 7.5% H2O2 by weight of 100 kg of cement. The test which was carried out in the experimental work were density, workability, strength, water absorption, the slump of air-entrained concrete and aggression resistance of air-entrained concrete against an acid attack such as H2SO4, etc. Total 48 No. of the concrete cube was cast for the experimental work. The result of the experiment work shows if H2O2 is used in the range of 5-6% it will provide better workability, less water absorption and improved resistance against acid attack with acceptable 5-7% decrease in compressive strength
