For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. Aggregates, which account for 60 to 75 percent of the total volume of concrete, are divided into two distinct categories--fine and coarse.

CVL3211 : Civil Engineering Materials Batching of concrete Batching of concrete Assume an example; 0.25m3 of M20 concrete with water cement ratio of 0.5 and air content 3% is to be formed, given speciﬁc gravities of cement sand and aggregates are 3, 2.6, 2.7. Calculate the weight of all the ingredients. Solution Volume of concrete= 0.25m3.

With concrete-making materials of given characteristics, and given job conditions (i.e., structural design and equip-ment for handling concrete), the variables generally under the control of a mix designer are as follows: the cement paste/aggregate ratio in the mixture, the water/cement ra-tio in the cement paste, the sand/coarse aggregate ...

M25 Concrete Grade | How to Calculate Cement, Sand, and Aggregate for Mix Design || By CivilGuruji

acteristics of a concrete mixture is called mix design. Characteristics can include: (1) fresh concrete properties; (2) required mechanical properties of hardened concrete such as strength and durability requirements; and (3) the inclusion, exclusion, or limits on specific ingredients. Mix design leads to the development of a concrete ...

For example, for M30 grade, the mix proportion can be 1:1:2, where 1 is the ratio of cement, 1 is the ratio of sand and 2 is the ratio of coarse aggregate based on volume or weight of materials. The strength is measured with concrete cube or cylinders by civil engineers at construction site.
