Physical and mechanical properties of foamed concrete, a literature review

Abstract

Foamed concrete is distinguished from regular concrete's lightweight, high strength-to-weight ratio, and exceptional rheological and thermally insulating qualities. Foamed concrete offers reduced manufacturing and shipping costs than conventional concrete and can be used for structural components. Reduced energy consumption and self-weight of the superstructure are achieved by using foamed concrete. This article provides a comprehensive look into the mechanical, functional, and physical characteristics of foam concrete and the materials and processes involved in their production. This quantitative literature review had two main goals: (1) to pinpoint research gaps and (2) to give readers a comprehensive grasp of the many ways in which certain cell types might be put to use. Since it is both lightweight and durable, foamed concrete is a great material. Foamed concrete is employed because it reduces the foundation and support columns' load, saving energy, time, and money. As a possible structural material, it offers savings in producing and transporting construction components over traditional concrete. This paper describes the qualities, building procedures, and materials that go into making foamed concrete. This critical review aims to introduce readers to foamed concrete and its potential uses in the modern building sector. Foamed concrete's strength and density can be affected by a number of factors, including the mix proportions used, the foam agent quality and quantity, and the manufacturing technique. Fly ash, silica fumes, plastiziers can be used to increase its compressive strength.
