· Quantity of aggregates in ft 3 = x = ft 3. Learn More Civil Engineering Interview Questions and Answers 4. Water Quantity. Quantity of water in liter depends upon the watercement ration and quantity of cement. In the above examples, I have calculated Weight of cement in m3 = m 3. Consider watercement ration = ...

Cement is the fine powder and it is amalgamated with water, sand, and gravel or crushed stone (fine and coarse aggregate), it develops the rocklike mass that is known as concrete. Read More How to Calculate Cement, Sand and Aggregate Quantity in Concrete

The quantity of water is usually expressed in litre per bag of cement. if water required for one bag of cement is 30 litres, the watercement ratio is equal to 30/50 = The watercement ratio should be such that it should impart a reasonable degree of workability to concrete, excess water affects the durability and strength of the concrete.

Quantity estimation of building materials is essentially required in any construction works and quantity of materials depend on the mix proportions of the concrete. In our previous article, we have already discussed how to calculate bricks in a wall. Today we will discuss how to calculate quantities of materials for different concrete mix ratio.

Therefore, the required amount of cement for 1 cubic meter of concrete is calculated to be = / = bags of cement. The following calculation is required to find out the quantities of materials for 1 m3 of concrete production: The weight of cement required = x 50 = kg. Weight of fine aggregate (sand) = x = 546 ...

The quantity of water for mixing will be equal to 50% of the cement quantity used for the mix. Plain cement concrete work: 1. Mix cement, sand, and aggregate in the ratio of cement 1: sand 2: aggregate 4 (1:2:4) on a clean dry surface. 2. Add water gradually in it to make a uniform concrete mix. 3.

· Let us assume that you have decided to mould your own blocks, and you have been faced with the challenge of estimating the quantity of cement and sand to purchase that will satisfy the construction requirement. This article will give you a guide on how to estimate the quantity of sand and cement required for moulding blocks in Nigeria. I am going to work .

Answer (1 of 5): 1:1:2 (1 part of cement : 1 part Sand: 2 part of CA) is for M25 Grade. Cement required for this ratio is [1/(1+1+2)]**1440 = 554 kg/m3 (usually Cement measured in Bags so 554*50= 11 Bags) (where is Dry to wet volume constant, .

Wet volume of concrete = 1 m³. Dry volume = Wet volume x (You can also take it as to, But it became standard practice to considering as multipliion factor). Dry volume of concrete = 1 x = m³. 1 Findout quantity of Cement. Quantity of cement = (Dry volume of concrete x cement ratio)/(sum of the ratio)

Grade of concrete M10, M15, M20, M25 depends on ratio of Cement, Sand and Aggregate. M20 is the most common for Home Builders.

· Cement concrete roads are either made of Plain cement concrete or Reinforced cement concrete. In order to determine the cost of construction and quantity of material to be used for the construction of any given road Cement Concrete Road Estimate is prepared. Cement Concrete road consists of a subgrade and concrete slab.

· Estimating the Quantities of Cement, Sand, and Gravel from Building Plan Generally, cement grade represents a higher strength cement than cement grade Hence, we will use Portlandlimestone cement grade and a concrete mix ratio of 1:2:4. Follow as we proceed to estimate the quantities of cement, sand, and granite that we need.

Considering voids in sands, we assume that materials consist of 60% voids. That is, for 1m 3 of wet cement mortar, 3 of materials are required. Now we calculate the volume of materials used in cement mortar based on its proportions. Let's say, the proportion of cement and sand in mortar is 1:X, where X is the volume of sand required.

Generally, M5, M10, M15 grades of concrete are used for PCC (plane cement concrete) work like leveling course, for bed footing etc. Unit weight of plain cement concrete (PCC) is 2400 kg/m 3 or 24 24 KN/m 3. Unit weight of reinforced cement concrete (RCC) is 2500 kg/m 3 .

Quantity of Concrete 250 Our calculation is based on fact that wastage in making and pouring concrete has already been considered by the requestee. Quantity of Coarse Aggregate 250 CFT. Quantity of Fine Aggregate 250 x 4/7 = 143 CFT. Rounded to 145 CFT. Quantity of Cement 250/7 = CFT/ CFT/Bag = 24 Bags
