ABSTRACT

This research aims to create environmentally friendly cellular concrete utilizing SPW as sand replacement, and addition of foam for pore spaces in the concrete. Nine different mixes of varying SPW replacement (10%, 25%, 50%), and foam content by total volume (10%, 15%, 20%) are tested for its density, compressive strength, specific heat capacity, and environmental impact through LCA. The categories evaluated are GWP, FPMF, OFHH and OFTE, TA, and TET. Overall, the optimum mix design is M-50P-20F, with a compressive strength of 3.59 MPa, dry bulk density of 1045 kg/m³ and specific heat capacity of 1.4484 kJ/kg°C. It outperformed all other mixes including the control mix in terms of environmental impact with it contributing the least in GWP, FPMF, OFHH, OFTE, and TA. For TET, the optimum mix contributed the least among other mixes except for the control mix due to the additional materials in the concrete.
