    摘要: A light concrete prepared from a mixture of Portland cement, cellular aggregate, and an admixture including a melamine-formaldehyde condensate carrying sulfo groups for reducing the need for mixing water, an alkaline earth metal stearate as a water repelling material, and polyethyleneglycol has greater mechanical strength at lower density than an otherwise identical concrete containing only two ingredients of the admixture.
