Water Absorption: Coarse Aggregate : 0.5% Fine Aggregate : 1.0 %. MIX DESIGN. Take Sand content as percentage of total aggregates = 36%. Select Water Cement Ratio = 0.43 for concrete grade M35 (From Fig 2. of I.S. 10262- 1982) Select Water Content = 172 Kg (From IS: 10262 for 20 mm nominal size of aggregates Maximum Water Content = 186 Kg/ M 3)
Aggregates directly influence the compressive strength of concrete. In a standard cubic metre of concrete, this amount of crushed rock forms a sturdy framework for the mix, while the size and shape of the aggregates will influence workability. 1 Cubic Meter of Concrete. 1m 3 of concrete = 150l water + 250kg cement + 700kg sand + 1200kg aggregates.
Ratio of water and cement is known as water cement ratio which is about 60 litre per bag cement for m5 grade of concrete. 1 bag cement required = 60 litre of water. 41.6 bags = 41.6×60= 2496 litre of water. So we have required water consumption in pcc 1:5:10 is approx 2496 litre of water for 100m2 having 150 mm thick slab.
Today we will discuss how to calculate quantities of materials for different concrete mix ratios. (Dry mix method) We will calculate quantities of materials for 1 m3 of concrete (By volume). …
=0.2171 cum. As we know, the density of cement is 1440 kg/cum and. Weight of 1 bag of cement = 50 kg. Therefore the volume of 1 bag of cement = 50/1440 =0.0347 cum. ∴ 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. Also Read
The amount of water needed to mix the concrete will be determined by how "workable" or how "wet or dry" you want the concrete mixture to be. On the concrete ticket you see above, there was 216 pounds of water added to the 8 yards of concrete when it was batched into the truck. That's 27 gallons of water per cubic yard of concrete. Water weighs ...
Vacuum concrete — a higher quantity of water is added to the concrete mix, and then the mixture is poured into the formwork. Permeable concrete — water is able to pass through it. Used in areas where storm water is an issue. Sprayed concrete — it is fabricated in the same way as ordinary concrete, but the way of placing it differs. It is ...
Let's say we have a concrete mix with a 1:2:4 ratio, and we want to calculate the quantity of water needed for 1 cubic meter of concrete. Step 1: Calculate the Mass of Cement (M_c) M_c = (1/7) * 1000 kg = 142.86 kg. Step 2: Calculate the Water-Cement Ratio (W/C)
The amount of water needed when mixing sand and cement depends on the specific mix ratio, the type of sand and cement used, and the desired consistency of the mix. As a general guideline, start with a small amount of water and gradually add more until the mix reaches a workable consistency.
Once the W/C ratio is determined use 186 kg water (for 20mm CA) to find out the qty. of cement per cum of concrete. Then determine the qty. of FA and CA with the help of formula given in IS:10262 ...

Ratio of water and cement is known as water cement ratio which is about 60 litre per bag cement for m5 grade of concrete. 1 bag cement required = 60 litre of water. 41.6 bags = 41.6×60= 2496 litre of water. So we have required water …
Weight of cement and cubic feet of sand and aggregate needed for different concrete grades. As mentioned earlier, 1.52 cubic meters of dry aggregate (cement + sand + aggregate) is required to produce 1 cubic meter of M7.5 and M5 concrete. Number of Cement bags and Volume of Sand and Aggregate required for different Concrete Grades:
the concrete as it melts. Using ice to re-place half of the water batched at air What temperature drop is required and how much concrete must be cooled? By Ward R. Malisch Using coarse aggregate that's been doused with cold water can lower concrete temperature by 10 degrees. A solid stream instead of a spray minimizes cold water's contact ...

Let's assume that the water cement ratio is 0.5. Remember the formula : W/c ratio =Water content /Cement content. Or. Water content= Cement content x W/c ratio. Water content = 476 Kg x 0.5 = 238 Kg. We know, 1 Kg =1 litre. So water content= 238 Kg. = 238 Litres. Add 5% wastage of water during mixing, handling, ∴ Water content = 5×238/100 ...
