普通混凝土的配合比是指混凝土的各组成材料之间的比例关系。可采用质量比亦可采用体积比,我国目前采用的是质量比。普通混凝土的组成材料主要包括水泥、粗骨料、细骨料和水,随着混凝土技术的发展,外加剂和掺和料的应用曰益普遍,因此,其掺量也是混凝土配合比设计时需选定的。因外加剂的型号、品种甚多,性能各异,掺合料的品种也逐渐增加,故在目前国家标准中,外加剂和掺合料的掺量只作原则规定。
Ordinary concrete mix refers to the proportion of the concrete composition of the material. Can be used than the mass ratio can also be used in volume ratio, China is currently using the mass ratio. Ordinary concrete composition materials include cement, coarse aggregate, fine aggregate and water. With the development of concrete technology, the application of admixture and admixture is said to be common, therefore, the dosage is also the concrete mix design time Selected. Due to the type of admixture, many varieties, different performance, the types of admixtures also gradually increased, so in the current national standards, admixture and admixture content only as a principle.
