Foamed concrete

A method of using air bubbles and catalyst in cement mortar

Reduce density

Enhance productivity

On-site production of KUIKcrete

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.

Emission of carbon dioxide (CO2) due to cement production:• 2.8 billion tonnes/yr

Aggregate consumption• 14 billion tonnes/yr

Several options to address the issue:

Foamed concrete as carbon sequestration media (CSM) Biomass aggregate to reduce the use of natural aggregate

CSM
