为了更合理地使用粉煤灰修筑高级路面,我们在1986年开始对粉煤灰水泥混凝土进行了系统的室内试验研究工作,并在此基础上修筑了95米的粉煤灰水泥混凝土试验路面,通过一年多观测,取得了很好的效果。从各方面性能来看,完全能满足高等级路要求,现将试验观测结果及其分析附后。一、原材料的试验 1.水泥:亚沟425~#,牡丹江525~#,纳河425~#; 2.砂:试验结果见表1; 3.石料:碎石、卵石两种,经磨耗试验,碎石为一级酸性石料,卵石为一级砾石,其颗粒级配见表2、3、4。 4.粉煤灰:采用哈尔滨化工热电厂,富拉尔基电厂与伊春林业电厂三种粉煤灰,其化
In order to make rational use of fly ash to build high-grade pavement, we started systematic laboratory research on fly-ash cement concrete in 1986 and built a 95-meter fly ash cement concrete test pavement on this basis. After more than a year of observation, we achieved good results. From all aspects of performance point of view, fully meet the high-level road requirements, test results and analysis are now attached. First, the test of raw materials 1. Cement: Yagou 425 ~ #, Mudanjiang 525 ~ #, Nahe 425 ~ # 2. Sand: Table 1 shows the test results; 3. Stone: gravel, pebble two, after the wear test , Gravel is an acid stone, pebbles for a gravel, the particle size distribution in Table 2,3,4. 4 fly ash: the Harbin Chemical Thermal Power Plant, Fulaerji Power Plant and Yichun Forestry Power Plant three kinds of fly ash, its
