Foamed concrete A method of using air bubbles and catalyst in cement mortar Reduce density Enhance productivity On-site production of KUIKcrete
SMART Apps Within 3 days, 1800m3 of foamed concrete (6m high) was cast. The total volume was about 180 units of low cost houses.

UTHM – with wisdom we explore… possibility to uptake 38% of CO2 (0.38 x 2.8 billion tonnes/yr) due to cement production with foamed concrete containing biomass aggregate, thus reducing natural aggregate consumption. www.1.net.my www.ashmann.com www.biomass.org.my
CSMEmission of carbondioxide (CO2) due tocement production:• 2.8 billion tonnes/yrAggregate consumption• 14 billion tonnes/yrSeveral options to address the issue: Foamed concrete as carbon sequestration media (CSM) Biomass aggregate to reduce the use of naturalaggregate 70
