Abstract
This project presents the results of the investigation conducted on a lightweight foamed concrete using different reagents; Sodium Lauryl Sulphate (SLS) and Lithofoam, with a view to determining its potential as a construction material in Nigeria. The properties investigated on the foamed concrete having target density of 1800kg/m3 were: workability, bulk density and compressive strength. The foamed concrete was developed using a w/c ratio of 0.5 and a mix ratio of 1:3:0.0025. Concrete specimens were produced using two different fine aggregate grades. Specimens were cured in water for 7, 21 and 28 days. The results revealed that the curing ages significantly affected the strength and that suitable strengths can be achieved using SLS as a foaming agent. The 28th day strengths for the concrete specimens were 11.27N/mm2 and 11.04N/mm2 respectively. These strengths were about 23.2% and 25.8% less than that achieved using the Lithofoam as the reagent.
