Aug 03, 2018· 1 Bag of cement in cubic metres = cubic meter How many CFT (Cubic Feet) = CFT Numbers of Bags in 1 cubic metre cement = Bags. Specific gravity of cement = Grade of cement = 33, 43, 53 Where 33, 43, 53 compressive strength of cement .

The Minimum grade of concrete for Plain Cement Concrete (PCC) is M15. The Minimum grade of concrete for Reinforced Cement Concrete (RCC) is M20. Concrete Grade and Mix Ratio Table. As per IS 456:2000, the grades less than M20 should not be used in RCC works. Group: Concrete Grade:

May 02, 2020· M20 Grade of Concrete requires approximate 200liters or 53 gallons of water The Quantity of Water required for different grades of concrete is stipulated below: In below ''M'' refers to Mix and value behind M refers to Compressive strength of concrete in KN/ at 28 days.

*Total quantity= Sum of the individual masses of fine and coarse aggregates, kg Proportion of fine aggregate to coarse aggregate (by mass) : Generally 1:2 but subject to an upper limit of 1: and a lower limit of 1:

Grade 43 cement is mainly used in: Ready mix concrete.() Reinforced cement concrete work () Precast concrete. (Example in Delhi Metro pillars) Silos and chimneys. IS 8112(1989) COVERS THE SPECIFICATION OF GRADE 43 ORDINARY PORTLAND CEMENT. GRADE 53 ORDINARY PORTLAND CEMENT: Fineness=225 m2/kg Compressive strength .

Due to the availability of higher grades in the cement, use of 33 grade cement has declined. Nowadays 33 grade cement is hardly manufactured. 02. 43 Grade Cement. 43 grade cement means that the compressive strength of the cement after 28 days is 43N/mm 2 when tested as per Indian Standards under standard conditions.

May 22, 2013· The grade 43 and 53 in cement mainly corresponds to the average compressive strength attained after 28 days ( 6724 hours) in mega pascals (Mpa) of at least three mortar cubes ( area of face 50 cm squared) composed of one part cement, 3 parts of standard s and ( conforming to IS 650:1966) by mass and P/4 ( P is the percentage of water required ...

I would suggest the ratio of 1:2:3 or 1::3 for M20 grade concrete and 1:2:4 or 1:: for M15 grade concrete. If you prepare concrete with your ration then the concrete will have too much sand. Too much sand causes shrinkage and this will not give highdensity concrete. Hence use 1:2:3 for good strength and 1:: for moderate strength.

I would suggest the ratio of 1:2:3 or 1::3 for M20 grade concrete and 1:2:4 or 1:: for M15 grade concrete. If you prepare concrete with your ration then the concrete will have too much sand. Too much sand causes shrinkage and this will not give highdensity concrete. Hence use 1:2:3 for good strength and 1:: for moderate strength.

The water–cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix. A lower ratio leads to higher strength and durability, but may make the mix difficult to work with and form. Workability can be resolved with the use of plasticizers or superplasticizers.. Often, the ratio refers to the ratio of water to cementitious materials, w/cm. .

Apr 21, 2019· Weight of Coarse Aggregates = x 1520 = kg ( tonnes) The above calculation you can use for all Grade of Concrete but just you have to put the different Grade of concrete like M10, M 15, M20, M25 etc. just here with grade of concrete you can change the proportion and the method is just above which I have discuss .

We find out the quantity of cement for 1cum Dry coefficient of cement is Unit weight of cement 1440 Then (1/(1++3))*= *1440=/m3 1 bag cement is equal to 50 kgs /50= So Approximately 8 bags of cement is for 1cum

With constant research and development in the field of cement technology and its manufacturing process,a M20 mix of "1::3″(by volume) would be too rich,over engineered and uneconomical (~ bags of cement per cum) and will ultimately result into a M30 concrete and above, the reason being latest generation of 53 grade OPC cement is ...

Example calculation Estimate the quantity of cement, sand and stone aggregate required for 1 cubic meter of 1:2:4 concrete mix. Ans. Materials required are 7 nos. of 50 kg bag of cement, m 3 of sand and m 3 of stone aggregate.

May 13, 2015· CONCRETE GRADE: M5 = 1:4:8 M10= 1:3:6 M15= 1:2:4 M20= 1::3 M25= 1:1:2 CLEAR COVER TO MAIN REINFORCEMENT: : 50 mm : 50 mm ...

Grade Designation According to Yunusa (2011) every concrete has its strength in N/mm2 when subject to test after 28 days of curing in any medium. The choice of concrete grade, depends on the purpose and usage as follows: Table 1: Concrete Grade Designation Concrete Grade N/mm2 Ratio Cement, Sand and Aggregates Usage

Mar 28, 2017· Hi .. So the design mix is M15, 1:2:4 Ratio sum = 1+2+4 = 7 Volume of concrete = 1 cubic metre ( wet volume ) Now dry volume of concrete = 45–55% increase in volume × wet volume Dry volume= 1× (assuming 52% increase in volume) Dry volume =...

the50 kg bag cement is equivalent to35ltr. now water should be added40% to45% by volume. (40*35/100 or45*35/100) =14 to16 ltrs of water per cement bag. by knowing the no. of cement bags you can calculate the total volume of water required using this method
