摘要
针对通村公路水泥混凝土配合比设计中存在的问题,首先将水泥混凝土按其抗弯拉强度分为3.0MPa、3.5MPa、4.0MPa、4.5MPa四个等级,然后结合山区公路筑路材料特点,通过室内路用性能试验研究,分别获得了不同集料类型的超低强度水泥混凝土的配合比,降低了通村公路工程造价。
According to the problems existing in mix proportion design of cement concrete of village road, firstly, the paper divided the cement concrete into four levels as 3MPa, 3.SMPa, 4MPa, 4.SMPa according to its flexural strength. Then, combined with the characteristics of mountainous highway construction ma- terials, through the study on indoor test of road performance, it obtained mix proportion of ultra low strength concrete with different aggregate types, which reduced the engineering cost of village road.
