Road large-slump premixed concrete mix proportion design method
The invention provides a design method for a mix proportion of road large-slump premixed concrete. The design method comprises the following steps: S1, calculating a mean value of 28d flexural-tensile strength of cement concrete for a road large-slump premixed concrete surface layer; s2, calculating a water-cement ratio or a water-binder ratio of the premixed concrete mixture with the large slump; s3, determining the sand ratio of the premixed concrete mixture with the large slump; s4, calculating the use amount of cement in the large-slump premixed concrete mixture; s5, calculating the use amount of water in the large-slump premixed concrete mixture; s6, calculating the use amount of the coarse aggregate and the fine aggregate in the large-slump premixed concrete mixture; s7, the mass ratio of all the materials of the large-slump premixed concrete is obtained, and the mix proportion design is obtained. According to the method, the steps for calculating the mix proportion of the large-slump premixed concrete are defined, the workability and the filling property of the mixture are improved while the durability of the large-slump premixed concrete pavement is guaranteed, and the method has high practicability.
本申请提供一种道路大坍落度预拌混凝土配合比设计方法，其包括：S1，计算道路大坍落度预拌混凝土面层用水泥混凝土配制28d弯拉强度的均值；S2，计算大坍落度预拌混凝土拌合物的水灰比或水胶比；S3，确定大坍落度预拌混凝土拌合物的砂率；S4，计算大坍落度预拌混凝土拌合物中水泥的用量；S5，计算大坍落度预拌混凝土拌合物中水的用量；S6，计算大坍落度预拌混凝土拌合物中粗集料和细集料的用量；S7，得到大坍落度预拌混凝土各材料的质量比，即得到配合比设计。该方法明确了大坍落度预拌混凝土配合比计算步骤，在保证大坍落度预拌混凝土路面耐久性的同时，提高了拌合物的工作性及填充性，具有较强的实用性。
