Investigation on Mechanical Strengths and Carbon Foot Print of Modified Foamed Concrete

This paper describes the work of a study carried out to investigate the mechanical strengths and carbon foot print of foamed concrete incorporating with local industrial wastes. Experiments were performed to obtain a minimum 28 days compressive strength of 15 MPa modified foamed concretes by using...
