Abstract

This paper is a study on physico-mechanical properties of foamed concrete (FC) containing ground brown bottle glass dosage protein foaming agent (PFA) in three proportions of 0.40, 0.50 and 0.60wt% of water. And also, synthetic gypsum (SG) was replaced partially ordinary Portland cement, type 1 with and without low pressure steam (LPS) condition for 8 hours then cured under ambient condition for 3, 7 and 28 days. Bulk density and compressive strength was determined. Furthermore, mineral phase and microstructure were analyzed. Testing results revealed PFA contents, curing after LPS and SG contents effect of changing development on bulk density and compressive strength. The BBG-FC specimen dosed PFA of 0.60 through LPS and cured under ambient 28 days provided highest compressive strength of 91 ksc and bulk density of 1,259 kg/m³. The BBG-FC blended two SG ratios specimens were met some class of TIS2601-2556 specification. Microstructure and mineralogy analysis revealed that the interconnected air-void pores, reformed gypsum crystals and needle-like ettringites.
