M25 concrete mix ratio cement. M25 refers to a concrete mix with a compressive strength of 25 MPa (megapascals) after 28 days. Here is the general mix design for M25 grade concrete: Cement: 300-325 kg/m^3; Fine aggregate (sand): 600-675 kg/m^3; Coarse aggregate: 975-1050 kg/m^3; Water: 150-175 kg/m^3; Admixture: 0 …

In conclusion, M25 grade concrete is a medium-strength concrete with a compressive strength of 25 MPa. Its mix design ratio is 1:1:2, and it contains around 300-350 kg of cement per cubic meter of concrete. The water-cement ratio for this grade is between 0.4 to 0.55, and the use of admixtures is not recommended.

The paper presents an experimental procedure for the design of self-compacting concrete mixes. The test results for acceptance characteristics of self-compacting concrete such as slump flow; J-ring, V-funnel and L-Box are presented. Further, compressive strength at the ages of 7, 28, and 90 days was also determined and results are included here.

The M30 concrete mix ratio is a proportion of ingredients used to achieve a particular strength in concrete. The ratio is 1:0.75:1.5, which means for every 1 part cement, you need 0.75 parts sand and 1.5 parts aggregates when making 1 cubic meter of concrete. For Concrete mix design, we use, IS 456, and IS 10262.

Method 3: Take a sample of each in a container/cistern (of equal volume) and fill them The CSA ratio of the M25 is 1: 1: 2, while that of the M30 is mix design (but is generally greater than M25). As the weight of the aggregate is dominating the mixture, the weight of the M30 sample will be greater. Thus, we can differentiate between samples.
