        The first is ordinary Portland cement, which can be used in grades 42.5 or 32.5. If you want to shorten the foam cement production cycle, it is better to use fast hard Portland cement or sulphoaluminate cement. The second is the active admixture of primary or secondary fly ash, slag micropowder, etc., which can increase the performance of foam concrete. The third is the foaming agent, which is indispensable. If it is fast-hard Portland cement or sulphoaluminate cement, it can be used with any kind of foaming agent. If it is ordinary Portland cement, it will condense slowly, easy to defoam, so high-grade foaming agent must be used. There is also a slurry stabilizer to improve stability.
