混凝土质量的好坏,既对结构物的安全,也对结构物的造价有很大影响,因此在施工中我们必须对混凝土的施工质量有足够的重视。1.混凝土强度及主要影响因素混凝土质量的主要指标之一是抗压强度,从混凝土强度表达式不难看出,混凝土抗压强度与混凝土用水水泥的强度成正比,按公式计算,当水灰比相等时,高标号水泥比低标号水泥配制出的混凝土抗压 The quality of concrete has a great influence on the safety of structures and on the cost of structures. Therefore, we must pay enough attention to the quality of concrete during construction. 1. Concrete Strength and Main Influencing Factors One of the main indicators of concrete quality is the compressive strength. It is not difficult to see from the concrete strength expression that the compressive strength of concrete is directly proportional to the strength of concrete with water, according to the formula, when the water-cement ratio When equal, high-grade cement compresses concrete less than low-grade cement
