A gas-forming agent is a chemical admixture which reacts with the hydroxide produced in the hydration process to produce minute bubbles of hydrogen gas throughout the cement matrix. It causes a slight expansion of plastic concrete and increases the bond between the rebars and the grout. Aluminium powder is the most commonly used gas-forming agent.

Enhancing the performance of concrete by using concrete admixtures is not a new concept, but it is a popular one. For The Rasmussen Group, a large construction management firm based in central Iowa, the choice of concrete admixture was fly ash - a by-product of the combustion of pulverized coal in electric power generation plants.

When pulverised coal is burnt to generate heat, the residue contains 80 per cent fly ash and 20 per cent bottom ash. The size of particles is largely dependent on the type of dust collection equipment. Fly ash is a complex material consisting of heterogeneous combinations of amorphous (glassy) and crystalline phases.
