Design method of mix proportion of high-durability machine-made sand concrete

The invention provides a design method of a mix proportion of high-durability machine-made sand concrete, and belongs to the technical field of building materials. According to the design method for the mix proportion of the high-durability machine-made sand concrete, machine-made sand and coarse aggregate are used as a stacking system according to a fullerene curve maximum compactness theory, and factors such as the powder content of the machine-made sand, the void ratio of the coarse aggregate and the thickness of mortar are considered, so that the method solves the problems of unreasonable compactness and durability design caused by neglecting the aggregate grading proportion in the existing machine-made sand concrete mix proportion design method from the design aspect. The invention provides a new method for the mix proportion design of the high-durability machine-made sand concrete. 本发明提供了一种高耐久性机制砂混凝土配合比的设计方法，属于建筑材料技术领域。该高耐久性机制砂混凝土配合比的设计方法，根据富勒曲线最大密实度理论，将机制砂和粗集料作为堆积体系，通过考虑机制砂石粉含量、粗集料空隙率、砂浆厚度等因素，从设计方面解决了现
