M150 is the grade of the concrete which will give an expected compressive strength of 150KG/cm2 or 15N/mm2.
.
In this regard, what is M in grade of concrete?
M stands for “MIX”, the ratio in which you have mixed the Cement, Sand and Aggregates. The Mix ratio for M20 grade of concrete is 1:1.5:3 (Cement:Sand:Aggregates). For different grades of Concrete, the mix ratio is different.
Secondly, what do you mean by m15 concrete? M15 means the characterestic strength of concrete after curing it for 28 days is 15N/mm2.
Moreover, what is m15 and m20 grade concrete?
Regular Grades of Concrete and their Uses

What is the meaning of m30 grade concrete?
M30 stands for Cube's characteristics strength and C30 cylindrical strength after a curing period of 28 days which represents 30 N/mm^2. M30 = 30 N/mm2 of Cube.

The different grades of concrete are given as M10, M15, M20, M25, M30, M35 and M40. 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.What is the strongest concrete mix ratio?
In making concrete strong, these ingredients should usually be mixed in a ratio of 1:2:3:0.5 to achieve maximum strength. That is 1 part cement, 2 parts sand, 3 parts gravel, and 0.5 part water.Why slump test is done?
The concrete slump test measures the consistency of fresh concrete before it sets. It is performed to check the workability of freshly made concrete, and therefore the ease with which concrete flows. The slump test is used to ensure uniformity for different loads of concrete under field conditions.What is the highest grade of concrete?

What does m20 mean?
M20 is one of the grade of the concrete. M refers the mix and 20 refers to the compressive strength of the concrete cube of dimension (. 15×. 15×. 15)m ,Which means that the compressive strength of that cube will not be less than 20 N/mm2.What is c35 concrete?
C35 concrete. Usually specified at design stage, this form of ready mix concrete is designed to comply with a compressive strength denoted by the class of mix. A C35 mix has a higher cement content inclusion, meaning that the strength of the mix is in the higher class of the design concrete products that we offer.How do you calculate a mix ratio?
HOW TO CALCULATE PERCENTAGE IF MIX RATIO IS KNOWN. Divide 1 by the total number of parts (water + solution). For example, if your mix ratio is 8:1 or 8 parts water to 1 part solution, there are (8 + 1) or 9 parts. The mixing percentage is 11.1% (1 divided by 9).What is m20 concrete used for?
