After two hours of laying of concrete, when the concrete has begun to harden, it shall be kept damp by covering with wet gunny bags for 24 hours. After 24 hours of placing PCC, keep the concrete surface moist by flooding with water or by covering with moist gunny bags. Curing of PCC may be done by either pouring water with buckets or with pipes.

You hear 5 bag mix all the time, which is a slightly rich (more portland cement) from 4.5 bags needed to make the 1 part portland cement 2 parts sand and 3 parts rock mixture: there are 27 cubic feet per yard, 1 bag (94 lb) of portland cement is 1 cubic foot so 1 yd has 4.5 cubic feet portland cement (4.5 bags) + 9 cubic feet of sand + 13.5 cubic feet of rock = 27 cubic feet total.

Understanding Concrete Grades . Based on strength, concrete is classified into different grades like M5, M7.5, M10, M15, M20 etc. In concrete grades, the letter "M" stands for "Mix" and the following number stands for characteristic compressive strength of concrete in 28 days in the Direct Compression test.

We have considered an entrained air of 2%. Thus the actual volume of concrete for 1 cubic meter of compacted concrete construction will be = 1 -0.02 = 0.98 m 3. Thus, the quantity of cement required for 1 cubic meter of concrete = 0.98/0.1345 = 7.29 bags of cement. The quantities of materials for 1 m3 of concrete production can be calculated as ...

When Portland cement is mixed with water, it acts as the glue to bond sand, gravel or crush stone to make concrete. Used for custom concrete mixes for both concrete slabs or for repairs where the concrete will be at least 2" (51 mm) thick. This item is unavailable for purchase online.

Plain Cement Concrete (PCC) is composed mixture of cement, aggregates, sand, water and chemical admixtures. Calculate portland cement concrete or PCC concrete mix design ratio in Cft and determine exactly how much quantity of cement, sand and aggregate is required for PCC .

Ratio of water and cement is known as water cement ratio which is about 45 litre per bag cement for m10 grade of concrete. 1 bag cement required = 45 litre of water. 51 bags = 51×45= 2295 litre of water. So we have required water consumption in pcc 1:4:8 is approx 2295 litre of water for 100m2 having 150 mm thick slab.

Finally, C = 336.14 Kg / m 3 of concrete. But from table 5 of IS456-2000, Minimum cement content required for moderate exposure condition for M15 grade concrete is = 240 Kg/m 3 of concrete. Greater of above two values will be the cement content. Hence, C = 336.14Kg

Sep 17, 2017· Concrete is described as per IS 456-2000 has designated the concrete mixes into two 1. Nominal Mix 2. Design Mix. In Nominal mix ratio of different material are already defined while in the design mix ratio is defined after the testing with different trial mixes. Grade of concrete are such as as M10, M15, M20, M25, M30, M35 and M40 e.t.c.

How to calculate quantity of cement in PCC, cement consumption in PCC 1:2:4, in this topic we know about how to calculate quantity of cement in PCC and cement consumption in PCC 1:2:4. we know that we have several grade of concrete like M5, M7.5, M10, M15, M20 and M25 and so more—. Generally PCC is standard for plain cement concrete which has a mix of cement .

With constant research and development in the field of cement technology and its manufacturing process,a M20 mix of "1:1.5:3″(by volume) would be too rich,over engineered and uneconomical (~7.5 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 ...

Ratio of water and cement is known as water cement ratio which is about 34 litre per bag cement for m10 grade of concrete. 1 bag cement required = 34 litre of water. 66.5 bags = 66.5×34= 2261 litre of water. So we have required water consumption in pcc 1:3:6 is approx 2261 litre of water for 100m2 having 150 mm thick slab.

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.
