前言石灰粉煤灰砂砾,是在破碎砂砾中,按一定比例掺入少量石灰和粉煤灰,加入适当水量,用拌和机拌和均匀的混合料。将混合料运往工地摊铺,在最佳含水量情况下辗压,成为一种整体的半刚性道路基层。其加固基本原理是:粉煤灰本身并无水硬性,且性质不活泼,但在适当水分下,加入石灰可激发其活性,并与石灰起化学反应,生成含

Preface Lime fly ash grit is crushed gravel, according to a certain percentage of mixed with a small amount of lime and fly ash, adding an appropriate amount of water, mix with a mixing machine mix. The mixture is transported to the site for paving and rolling at optimum moisture content to form a unitary semi-rigid road base. The basic principle of its reinforcement is: fly ash itself is not hydraulic, and the nature is not active, but under the appropriate moisture, adding lime can stimulate its activity, and chemical reaction with lime to produce containing
