道路水泥是属硅酸盐系统的特种水泥,以道路硅酸盐水泥熟料,加入适量的石膏,磨细制成的水硬性胶凝材料。硅酸钙含量较高,铝酸三钙含量较低。具有磨耗小、收缩小、抗折强度高的特点。适用于公路和城市道路的路面和飞机场跑道工程使用。道路水泥混凝土与其它土建工程所用水泥混凝土相比,明显地应该具备以下特点: 1.要求抗折强度高众所周知,水泥混凝土是一种脆性材料,具有高的抗压强度,
Road cement is a special silicate cement system to Portland Portland cement clinker, adding the right amount of gypsum, ground hydraulic cementitious material made. High content of calcium silicate, tricalcium aluminate content is lower. With a small wear, shrinkage, high flexural strength characteristics. Suitable for road and urban road pavement and airport runway projects. Compared with cement concrete used in other civil engineering, road cement concrete should obviously have the following characteristics: 1. Require high flexural strength It is well known that cement concrete is a brittle material with high compressive strength,
