我单位试验室根据多年的实践,总结出一套简便的普通混凝土配合比设计方法,即固定石子用量法。一,方法特点普通混凝土配合比简便设计方法是在设计普通混凝土配合比时,在水、水泥用量按常规方法确定后,用某种方法根据石子的规格、品种,先确定出石子的用量,而后计算砂 According to the practice of many years, the unit laboratory of our company has summarized a set of simple ordinary concrete mix ratio design method, namely fixed stone dosage method. I. Method Features The simple design method for the mix ratio of ordinary concrete is to design the mix proportion of ordinary concrete. After the amount of water and cement are determined according to the conventional methods, some method is used to determine the amount of stone according to the specifications and types of the stone. Calculating sand
