A classification of studies on properties of foam concrete
TLDR
In this article, the authors classify literature on foam concrete in terms of constituent materials (foaming agent, cement and other fillers used), mix proportioning, production methods, fresh and hardened properties of foam concrete.Abstract:
Though foam concrete was initially envisaged as a void filling and insulation material, there have been renewed interest in its structural characteristics in view of its lighter weight, savings in material and potential for large scale utilization of wastes like fly ash. The focus of this paper is to classify literature on foam concrete in terms of constituent materials (foaming agent, cement and other fillers used), mix proportioning, production methods, fresh and hardened properties of foam concrete. Based on the review, the following research needs have been identified: (i) developing affordable foaming agent and foam generator, (ii) investigation on compatibility between foaming agent and chemical admixtures, use of lightweight coarse aggregate and reinforcement including fibers, (iii) durability studies, and (iv) factors influencing foam concrete production viz., mixing, transporting and pumping.read more

Preliminary views on the potential of foamed concrete as a structural material
M. R. Jones,A. McCarthy +1 more
TL;DR: In this paper, a laboratory study of the development of foamed concrete, utilising two types of fly ash, with the potential for use in structural applications, was described, where fine fly ash (i.e. to BS EN 450) was used to partially replace Portland cement and coarse fly ash to replace sand fine aggregate.
