Get PriceJan 30, 2015So concrete with 2:1 sand cement ratio is bomb proof, next is 2.5:1 then 3:1 3.5:1 and 4:1 not sure if there is use for weaker mixes. 3:1 is middle of the road stuff, yet since it has 50% more sand than the 2:1 mix, it must have more coarse aggregate so to me 3:1 mix should have 4 parts of stone, yet some websites do say 3/3/1 or rather 1/3/3
Get PriceAnswer (1 of 4): Do you mean concrete which is a mixture of Cement, sand and gravel or blue metal or aggregate?

Get Price🕑 Reading time: 1 minute Quantity of materials such as cement, sand, coarse aggregates and water required per cubic meter of concrete and mortar for different mix proportions varies with the mix design of the concrete and mortar respectively. Following table gives the estimated quantity of materials required per cubic meter of mortar and concrete for various nominal mixes.
Get PriceAnswer (1 of 8): ix ratio of M25 grade is 1:1:2 (cement:sand:coarse aggregates) Assuming volume of concrete as 1 m^3 Therefore, Dry volume of concrete =1 x 1.54 =1.54 m^3 cement = (1.54 x 1)/(1+1+2) =1.54/4 = 0.385 m^3 since, Density of cement = 1440 kg/m^3 cement = 0.385 x 1440=554.4 kg =
Get PriceMay 17, 2017The Concrete mix ratio for M20 grade of concrete is 1:1.5:3 that mean 1 part of cement, 1.5 part of sand (fine aggregate) and 3 parts of aggregate (crushed stone) in volume and then batched for mixing. To know the Concrete Mix Design follow below:-. Mix Design (M) = Cement: Sand
Get PriceStep 6: Mix calculation . The mix calculations per unit weight of concrete . a) Volume of concrete = 1m. 3. b) Volume of cement = mass of cement / specific gravity of cement x (1/1000) = 430/3.14 x 1/1000 = 0.136 m. 3 . c) Volume of water = mass of water / specific . gravity of water x 1/1000 = 172/1 x 1/1000 = 0.172m. 3

Get PriceMar 02, 2020For example, a simple sand and cement mix should be at least 3 part sand (the aggregate) to one part cement. A strong concrete mix would be something like 1:3:5 (Cement, Sand, Coarse Gravel). In this case, both the sand and gravel are the aggregate. In pre-mix concrete, the aggregate is already mixed with the cement.

Get PriceJul 16, 2020A concrete mix ratio is usually expressed by a set of numbers separated by colons, as is the case with a 1:2:3 ratio. This tells the mixer that they need to add 1 part cement powder, 2 parts sand, and 3 parts aggregate in order to create the desired concrete consistency. Water is not included in these ratios, though, because it can vary more
