It is the grade of concrete which indicates the strength of concrete after 28 days curing. M #) means the strength of concrete after 28 days of curing will be 30 N/mm2 . The grade of concrete for ...
The grade of the concrete means the concrete compression resistance after 28 days. It is done in Newtons per square millimetre. A concrete of Grade C30 means that the concrete will have a compresion resistance (withstanding a compression) of 30 N/mm2 per square millimetre in 28 days.
Quantity of Cement required for 1 CUM of Concrete is = Dry volume of concrete * (Ratio of cement / Total Ratio of Mix) * Density of Cement. = 1.54*(1/7)*1440 =316.8 Kg’s
The grade of concrete is also denoted as C16/20, C20/25, C25/30, etc., which means Concrete Strength Class (C) the number behind C refers to Compressive strength of Concrete in N/mm 2 when tested with Cylinder / Cube.

M-30 CONCRETE MIX DESIGN . As per IS 10262-2009 & MORT&H . A-1. Stipulations for Proportioning: 1. Grade Designation : M30: 2. Type of Cement: OPC 53 grade confirming to IS-12269-1987
Cement Grade : Cement type/grade locally available that can be made available throughout construction period Workability : Placing condition of concrete governs its workability, low – slump of 25-75 mm (lightly reinforced sections in slab, beam, column) to high – slump of 100-150 mm (slip form, pumped concrete) .
The grade of the concrete means the concrete compression resistance after 28 days. It is done in Newtons per square millimetre. A concrete of Grade C30 means that the concrete will have a ...
How to Calculate Quantities of Cement, Sand and Aggregate for Nominal Concrete Mix (1:2:4)? Mix design is a process of determining the right quality materials and their relative proportions to prepare concrete of desired properties like workability, strength, setting time and durability.
how do we calculate quantity of cement , sand and aggregates in 1 m3 of M30 grade concrete ?.. Answer / a p s chandel Dry Density of the concrete mix=15.4 to15.7
To find out Quantity of Concrete ( Cement , Sand and Aggregate ) We have different Grade of Concrete and different Grade of concrete has different ratio for Cement , sand and Aggregate which are given below. M10 Ratio 1: 3 : 6 Here 1 is cement , 3 is Sand and 6 is Aggregate M 15 Ratio 1: 2 : 4 Here 1 is cement , 2 is Sand and 4 is Aggregate M20 Ratio 1: 1.5 : 3 Here 1 is cement , 1.5 is Sand ...
Proportioning of concrete is the process of selecting quantity of cement, sand, coarse aggregate and water in concrete to obtain desired strength and quality. The proportions of coarse aggregate, cement and water should be such that the resulting concrete has the following properties: When concrete
Concrete Mix Design – M 20 Grade Of Concrete. b) Sand as percentage of total aggregate by absolute volume = 35 %. Thus, The final mix proportions of M-20 grade of concrete become:- i need to find
Following is a simple method used by engineers to calculate cement, sand and aggregate to produce different grade of concrete like M5, M7.5, M10, M15 and M20. if you don’t want to learn the math involved in the design, you can use the table given at the end of the article to produce different grade of concrete.

concrete grade: m5 = 1:4:8 m10= 1:3:6 m15= 1:2:4 m20= 1:1.5:3 m25= 1:1:2 clear cover to main reinforcement: 1.footings : 50 mm 2.raft foundation.top : 50 mm
As, the quantity of concrete required for large constructions are huge, economy in quantity of materials such as cement makes the project construction economical. Concrete Mix design of M20, M25, M30 and higher grade of concrete can be calculated from example below.
now we can use absolute volume of cement = ((0.50)/((3.15x 10)) = 0.0158 cubic meter, where 0.50kN is weight of one cement bag, 3.15 specific gravity of cement and 10 unit weight of water..
