Experimental Investigation on Durability Properties of Foam Concrete Using Fiber

Abstract

The experimental analysis of the compressive strength and durability qualities of lightweight concrete mixtures containing fiber and fine particles is the main focus of this study.  The relationship between the density and compressive strength of concrete mixtures with varying proportions and durability characteristics, such as water absorption and acid attack, is proposed in this work.  Foam concrete is composed of cement, fine aggregate, water, and a foaming agent. It is a lightweight concrete with densities ranging from 300 to 1800 kg/m³.  Fibre reinforced foam concrete, or FRFC, is utilized in addition to foam concrete fiber.  Fiber consumption prevents weakening, shrinking, and cracking.  The ingredients of the concrete used in this study are fly ash, cement, recron-3s fiber, artificial foaming agent, and powdered marble sludge as a filler.  The target design density for each specimen is 1600 kg/m3.  Foam concrete is treated with recron-3s fiber at a rate of 0.2% to 0.4%. An increase in fiber content results in stronger concrete.
