摘要
调整材料配比配制大掺量(≥30%拌和物总量)粉煤灰砼路面砖,使产品的力学性能达到规范要求并能降低成本。
By adjusting material formula, concrete paving units are made with a richer mix (more than 30 per cent weight of the mix )of coal ash and the mechanical properties of the units have met the requirement of standard and the costs have been reduced.
