Road premixed concrete slag powder mixing amount determination method
The invention discloses a method for determining the mixing amount of slag powder in road premixed concrete. The method comprises the following steps: (1) calculating the average value of 28d flexural tensile strength of prepared concrete; 2) determining a concrete segregation coefficient; 3) calculating and determining the water-binder ratio of the concrete; and 4) calculating the mixing amount of the slag powder according to the 28d flexural tensile strength mean value of the concrete in the step 1), the concrete segregation coefficient in the step 2) and the water-binder ratio of the concrete in the step 3). The method can determine the mixing amount of the slag powder in the road premixed concrete, shortens the design period of the mix proportion of the concrete, saves manpower and material resources, and reduces the construction cost.
本发明公开了一种道路预拌混凝土矿渣粉掺量确定方法，其包括如下步骤：1)计算配制混凝土28d抗弯拉强度均值；2)确定混凝土离析系数；3)计算确定混凝土水胶比；4)根据步骤1)的混凝土28d抗弯拉强度均值、步骤2)的混凝土离析系数、步骤3)的混凝土水胶比计算矿渣粉掺量。本发明能确定道路预拌混凝土中矿渣粉掺量，缩短混凝土配合比设计周期，节约了人力物力，降低了施工成本。
