Physical and mechanical properties of foam concretes containing granulated blast furnace slag as fine aggregate

Abstract

In recent years, industrial by-products have been considered as a promising waste-based material in the production of concrete for development of an eco-friendly construction material. An experimental study on the properties of foam concretes, made with a protein-based foam agent, containing fly ash (FA) as binder and granulated blast furnace slag (GBS) as fine aggregate is presented in this paper. A total of nine batches of foam concretes were manufactured and tests were performed to evaluate the porosity, bulk density, compressive strength, water absorption, ultrasound velocity, and thermal conductivity. To explain the reasons for the obtained experimental results microstructural analysis ..
