【Abstract】 Among all ingredients used to mix the concrete, the gravel aggregates act as the skeletons of the concrete. While the cave degree remains unchanged, the different proportions of gravel aggregates applied may directly affect various elements such as the ratio of water to mortar, the consumption of water and cement, the compressive strength of the concrete. The quality of aggregate application in concrete has significant implications on the concrete quality and economic benefits.更多还原
