Concrete is a composite material used for the construction purpose. Mixing Ratio is 1:5:10 ( 1 part of cement, 5 parts of sand and 10 parts of aggregate). Grade of concrete is defined as the minimum strength the concrete must posses after 28 days of construction with proper quality control. There are some other special grades of cement available for specific needs. So, suitable grade of concrete can be selected based on structural requirements. Different grades of concrete : (same as M5). Concrete Characteristics. In the classification of concrete mix, the letter M denote Mix design, and the Numbers represent the predetermined works cube strength of 15cm cube after curing of 28 days in N/mm2. It is the widely used construction material. For making concrete we use cement, sand, aggregate, and water which are mixed with certain ratio and concrete is cast and put in a cube of 150 mm size and put in a water bath for 28 days and afterward, it is tested in a compression test. It is not suitable for large scale projects. The capacity of concrete is reported in psi – pounds per sq. Grade of concrete is defined as the minimum strength the concrete must posses after 28 days of construction with proper quality control. This concrete offers mix proportions based on locally available material and offers economy in construction if large scale concrete construction is carried out. M10. It can be used in trench fills, general floor binding, agricultural formations and drainage. For example, an M5 grade has the proportions of 1 : 5 : 10, where one is the cement, five is the sand and ten is the coarse aggregate, based on volume or weight of materials. Grades of concrete. In concrete the cement and water mix which form a paste matrix which fills the voids between the coarse aggregate and hardens over time. It gains 15 N/mm² compressive strength in 28 days. It gains 10 N/mm² compressive strength in 28 days. Thus, concrete is known by its compressive strength. June 5, 2020.
