Concrete rated at 6,000 psi or higher is considered highperformance concrete, and is used for heavyduty commercial applications. Some specialty projects use 10,000 psi concrete, and two skyscrapers in Seattle, Washington, incorporate highperformance concrete rated at 19,000 psi, according to the Portland Cement Association.

By Raj Mohammad Khan. Following table shows the M30 Mix Designs as per IS, hope this helps all civil engineers here
We use different grades of concrete for different parts of the building. We could say the grade of concrete is the only thing we do care lot while concreting. In this post, we are going to explain that in detail. Grades of Concrete Actually, what do we mean by grade of concrete.? Concrete grades are [.]
Nov 27, 2018· How To Calculate Water Content For 1 m³ M25 Concrete? The calculation of water content for 1 m³ M25 concrete is very easy and simple. We just need to know: 1. Consumption of cement per m³ 2. Watercement ratio. Here, Grade of concrete is M25. If it''s a design mix, both of these parameters shall [.]
May 17, 2017· To calculate the individual quantities of cement, sand and aggregate required for 1m 3 assume a nominal mix grade of concrete such as M20. You can use same method to calculate any grade of concrete. Concrete Mix Design for M20 Grade Concrete:Now let us consider M20 grade concrete; As per IS456:2000, M20 Grade concrete proportion is = 1 : : 3
A standard sidewalk grade of concrete would be 1 part cement, 2 parts sand, 3 parts gravel so the sidewalk needs cu ft of cement about 87 pounds worth plus sand and gravel.
Concrete Mix Design As Per Indian Standard Code ... From the quantities of water and cement per unit volume of concrete and the percentage of sand already determined in steps 6 and 7 above, calculate the content of coarse and fine aggregates per unit volume of concrete from the following relations: ... alwys prefer M20 or M25 grade of concrete ...
M25 = Compressive strength of a 150 mm cube of this concrete after 28 days will have a strength of 25 Newton / mm2. How different grade of concrete is made is just not the issue of what amount of cement is to be used but what type of cement, aggregate sand is being used also effects the stregth and thereby the grade.
IS 456–2000 has designated concrete mix into a number of grades like M10, M15, M20, M25 etc. Here M refer to Mix Ratio For M10 it is (1:3:6) For M15 (1:2:4) For M20 (1::3) For M25 (1:1:2) Note M25 concrete mix will attain a characteristic comp...
Concrete Mix Design Calculation for M20, M25, M30 Concrete with Procedure Example Home / Concrete Technology / Concrete Mix Design Calculation for M20, M25, M30 Concrete with Procedure Example Concrete mix design is the process of finding right proportions of cement, sand and aggregates for concrete to achieve target strength in structures.
Hence if you want to produce M20, M15 and M10 grade concrete, the total dry volume of cement sand and aggregate you require will be cubic meters, and if you want to produce and M5 grade concrete the total dry volume you will require will be cubic meters. I have seen in many websites that they confuse with value for the total dry ...

Understanding Grades of Concrete. Grades of concrete are defined by the strength and composition of the concrete, and the minimum strength the concrete should have following 28 days of initial construction. The grade of concrete is understood in measurements of MPa, where M stands for mix and the MPa denotes the overall strength.
Cement is an essential construction material, which is extensively used in the modernage of construction. Cement is a prominent ingredient for concrete, mortar, and plaster, etc. Cement is available in different grades. The strength of the concrete mix is dependent on the grade of cement.
M40 grade stands for it''s a mix of concrete with a characteristic compressive strength of 40 N/mm 2. The mix design procedure for M40 grade concrete as per ACI Method is discussed. For very good degree of super vision standard deviation value for required grade of concrete is as follows. Effective ...
