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.
Hi .. So the design mix is M15 i.e, 1:2:4 Ratio sum = 1+2+4 = 7 Volume of concrete = 1 cubic metre ( wet volume ) Now dry volume of concrete = 45–55% increase in volume × wet volume Dry volume= 1×1.52 (assuming 52% increase in volume) Dry volume =...
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.
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 ...
Here is the simplest term of your question: M10 M15 M20 etc. are all grades of concrete in the Indian Standard issued by Bureau of Indian Standards. The 'M' denotes 'Mix' followed by a number representing the compression strength of that mix in N/mm^2.
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.
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.
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 .
Placing and Compaction of PCC: Make sure brick soling/sand bed level for PCC is ok. Make formwork for PCC with wooden planks as per specified dimensions. Clean dust and foreign materials from concreting area. Spread polythene over the bed of PCC. Make level pillars of fresh concrete in the area at suitable intervals but not more than 2m c/c ...
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.
0.178/0.03472=5.15 Approximate Cement bags. Sand=0.178*2.5 =0.44m3 Aggricate=0.178*5 ... How much 1 cum of M15, M20 & M25 concrete weigh? 0 Answers Aptitude, reasoning, quants, verbal and technical question ... What is the amount on nails per bag needed for 1m square of wooden form work? 2 Answers Ansal Housing, College School Exams Tests, say ...
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 ...
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.
Aug 01, 2019· In General Condition Lot of builders and Subcontractors are sublating this work on Sqft basis or Per Bag basis to Subcontractor or Concrete gang Who can do it on PCC Rs. 6.00/ Sqft and Plum Concrete in 8.50 to 9.00 Rs. Per Cuft that is 300 Per Cum

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

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.
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.
May 17, 2017· As per IS456:2000, Different grades of concrete are classified into M5, M7.5, M10, M15 etc., whereas M stands for Mix and the number behind M stands for Characteristic Compressive strength(fck) of the concrete in N/mm 2 @28 days when checked with 15cm×15cm×15cm cube in direct compression test.
