广泛地使用粉煤灰石灰砂砾混合料作为道路工程基层材料,提高了道路质量,延长了道路使用寿命。为了了解粉煤灰石灰砂砾混合料在不同温度下,强度增长的情况,使我们更好地掌握粉煤灰石灰砂砾混合料的施工工艺和控制生产和施工的有利条件,我们进行了粉煤灰石灰砂砾混合料的强度试验。我们的试验用了半年时间,制作了60组试件。养护温度分别为5℃,10℃,15℃,20℃,25℃,30℃等。养护龄期分别为3、7、14、21、28天等。用压力机以压实法制试件,用自制的FL200-40型高低温恒温箱
Extensive use of fly ash lime grit mixture as the grassroots road construction materials, improve the quality of the road, extending the life of the road. In order to understand the strength of fly ash lime grit mixture at different temperatures, so that we can better grasp the construction process of fly ash lime grit mixture and control the production and construction of favorable conditions, we carried out the fly ash Strength Test of Lime Grit Mixture. Our experiment took six months to make 60 sets of test pieces. The curing temperature is 5 ℃, 10 ℃, 15 ℃, 20 ℃, 25 ℃, 30 ℃ and so on. Maintenance age were 3,7,14,21,28 days and so on. Using press to compaction legal specimen, with homemade FL200-40 type high and low temperature incubator
