摘要
在水泥混凝土 (砼 )配合成份中 ,起骨架作用的碎石颗粒级配组成 ,在坍落度不变的情况下 ,分档比例不同 ,会直接影响水灰比、水和水泥用量以及砼的抗压强度等 ,重视砼骨料颗粒级配质量 ,对提高砼质量和经济效益 。
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.
