How much cement and sand is required for Mortar 1:4?

· Volume of mortar = 1 m3 Mix ratio = 1:4 Dry volume of mortar = wet volume x 1.33 here 1:33 is multiplication factor ( ranges from 1.30 to 1.35) Dry volume = 1 x 1.33 = 1.33 m3 Quantity of cement Quantity of cement = (dry volume of mortar x cement .

· Since we know the ratio of cement to sand (1:2) and cement to aggregate (1:4) Volume of Sand required would be = 0.035*2 = 0.07 cubic meter (cum) Volume of Aggregate required would be = 0.035*4 = 0.14 cubic meter (cum)

· Now we start calculation for find Cement, Sand and Aggregate quality in 1 cubic meter concrete. CALCULATION FOR CEMENT QUANTITY; Cement= (1/5.5) x 1.54 = 0.28 m 3 ∴ 1 is a part of cement, 5.5 is sum of ratio Density of Cement is 1440/m 3 = 0.28 x 1440 = 403.2 kg We know each bag of cement is 50 kg

The proportions of cement, sand, coarse aggregate and water plays an important role in determining the fresh and hardended properties of concrete. So care should be taken while calculating the amount of Cement, Sand and Aggregate required for 1 Cubic meter of Concrete. Method-1: DLBD method to determine material requirement for 1 Cum concrete The DLBD (Dry Loose …

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, 0.42 m 3 of sand and 0.83 m 3 of stone aggregate.

Hence in order to prepare 1 cubic meter of M20, M15 and M10 concrete you need 1.57 cubic meters of “total dry volume:” of cement, sand and aggregate and incase of M7.5 and M5 concrete you need 1.52 cubic meters total dry volume of cement sand and aggregate.

· ∴ No. of cement bags required in 1 cubic meter = 0.2171/0.0347 = 6.25 bags. Note: You can use the same formula for calculating cement for other nominal mixes.

Calculating Quantities of Materials for per cubic meter or cubic feet or cubic yards concrete. Consider concrete with mix proportion of 1:1.5:3 where, 1 is part of cement, 1.5 is part of fine aggregates and 3 is part of coarse aggregates of maximum size of 20mm. The water cement ratio required for mixing of concrete is taken as 0.45.

for 15MPa, as per Indian code, its mix ratio is 1:2:4, and for this mix, it is shown in the above table that, cement required is 310kg of cement or 6.2 number of bags of cement, 0.434 cubic meter of sand (FA) and 0.868 cubic meter of coarse aggregate or stone.

sand 3 2.5 2 stone or gravel 5 4 3 Mix (as per concrete use) No. 20kg bags of cement cubic metres (m3) of sand cubic metres (m3) cement sand stone of stone 1 2 3 16 0.5 0.8 1 2.5 4 13 0.5 0.8 1 3 5 11 0.5 0.9 *Slab thickness in mm. 3. Decide whether to use: (a) Premix concrete from a readymix supplier (b) Bagged cement, sand and stone (c .

Dry volume of concrete is equal to 1× 1.54 = 1.54 m3 ( cubic meter) step 2 :-m25 nominal mix ratio is 1:1:2,in which one part is cement, one part is sand & two part is aggregate, then total mix proportion is equal to 1+1+2 = 4, and part of cement is equal to 1/4, part of sand is equal to 1/4 & part of aggregate is equal to 2/4

Hence in order to prepare 1 cubic meter of M20, M15 and M10 concrete you need 1.57 cubic meters of “total dry volume:” of cement, sand and aggregate and incase of M7.5 and M5 concrete you need 1.52 cubic meters total dry volume of cement sand and aggregate.

for 15MPa, as per Indian code, its mix ratio is 1:2:4, and for this mix, it is shown in the above table that, cement required is 310kg of cement or 6.2 number of bags of cement, 0.434 cubic meter of sand (FA) and 0.868 cubic meter of coarse aggregate or stone.

· ∴ No. of cement bags required in 1 cubic meter = 0.2171/0.0347 = 6.25 bags. Note: You can use the same formula for calculating cement for other nominal mixes.

From the IS 456-2000 table, ratio of volume of coarse aggregate to volume of total aggregate, for 20mm nominal maximum size aggregate and zone-2 fine aggregate. Therefore, P = 0.62

· It may take long time for me to type here (because i am not that good at typing). i calculated on a paper, so that i can save my time and energy too :-) have a look at this image let me tell you one thing i am uploading my class note of whole proc.

M20 (1 cement :1.5 sand :3 stone/brick aggregate). To determine the proportions you have to perform mix design, for this you have to find out the sp.gr. of cement, CA, FA, and water cement ratio .

sand 3 2.5 2 stone or gravel 5 4 3 Mix (as per concrete use) No. 20kg bags of cement cubic metres (m3) of sand cubic metres (m3) cement sand stone of stone 1 2 3 16 0.5 0.8 1 2.5 4 13 0.5 0.8 1 3 5 11 0.5 0.9 *Slab thickness in mm. 3. Decide whether to use: (a) Premix concrete from a readymix supplier (b) Bagged cement, sand and stone (c .

Cement Mortar Ratio for wall plastering 1:6; Cement Mortar Ratio for ceiling plastering 1:4; Plastering thickness should not be more than 12-15 mm. If there is a need for an additional coat don’t do that at one go. Ensure you are using good quality of cement & Sand (In silt content test, we have discussed how bad sand quality affects the work)

Volume of 1 brick with mortar = 200 X 100 X 100 ( 10 mm mortar thickness on all sides) = 0.2 X 0.1 X 0.1 . Volume of brick with mortar = 0.002 Cum (m 3) Therefore, Number of bricks required for 1 cubic metre = 1/0.002 = 500 No.s. Volume of bricks without mortar

· Nominal Mix is generally adopted for small scale constructions. In this type of mix, the mix ratios and concrete constituent proportions are prefixed and specified. Eg: M20(1:1.5:3); the quantity of cement, sand and aggregate is batched in volume as per the fixed ratio 1:1.5:3.

1:2:4:: cement: fine aggregate : Coarse Aggregate. Cement required = 01 bag = 36 liters (36 cc) = 50 kg. For batching ease, the farma/measuring box, dimensions should be selected to match volume of a cement bag i.e. 36 liter or 36 cc (cubic centimeter), as the cement is added per bag

Concrete mix ratio of 1:3:3 – On mixing 1 part cement, 3 parts sand with 3 parts aggregate produces concrete with a compressive strength of 3000 psi.. On mixing water with the three ingredients, a paste is formed that binds them together till the concrete mix gets hardened.The strength concrete is inversely proportional to the water/cement ratio.

now come to the ratio of concrete which is 1:2:4 so sum of the ratio will be 1+2+4=7 calculating separately each material: Cement: 1/7x154 = 22 cubic feet where 1 bag of cement measured 1.25 cubic feet approx therefore 22/1.25 = 17.6 bags of cement. 1 bag contains 50kg cement so total cement by weight we need for 100 cubic feet concrete = 17 .
