20191127ensp0183ensp concrete mix design belongs to the method of determining concrete mix proportion according to the proportion of cement sand and coarse aggregate. For example, a concrete mix proportion of 124 means that the proportion of cement fine aggregate and coarse aggregate is 124, or the mixture is composed of one part of cement and two parts of fine aggregate

Therefore, concrete is known for its compressive strength, M20 and M25 are the most common concrete grades, and higher grades of concrete are used for the compressive strength of concrete in extremely harsh and extreme environments, such as loads. The strength of concrete is also a quality, for the same concrete mixture, its quality changes greatly

These materials generate additional CSH gels by reacting with the hydration products of Portland cement, giving the concrete extra strength. If chemical admixtures are not used in the part of paste which is responsible for concrete strength, it is difficult to produce high strength concrete mixture. The usual practice is to use superplasticizer
