Sub total cost of material = cement cost + sand cost + aggregate cost = 1020 +669 + 1674 = INR 3363. step 6, labour rate and charges :- consider one mason and 2 helper completed 1 cubic metre of concrete work in 8 hour, per mason rate INR 600 and per Helper rate 400, but in mass concreting labour rate for 1m3 PPC work is INR 850.
5 inches = 0.42 feet. 8 inches = 0.67 feet. 11 inches = 0.92 feet. 3 inches = 0.25 feet. 6 inches = 0.5 feet. 9 inches = 0.75 feet. This same principle applies when dealing in metric. If you enter your first two measurements, (for example, 5 metres x 3 metres) and your depth is 6 inches or 150mm, you would enter this as 5m x 4m x 0.150 = 2.3 ...
Aug 07, 2019· The right amounts of ballast or sand-aggregate can also be expressed in simple ratios. So for the concrete mix mentioned above, your cement: sand: aggregate ratio should be 1:2:4 or ballast to cement ratio of 6 to 1. For a low-grade concrete with 10MPa strength, the perfect ratio should be 1:3:6. For 30MPa concrete use 1:0.75:1.5.
Mixing Concrete . The three main options for mixing concrete are: Mixing by hand - this is probably only suitable where less than about ¼m³ of concrete is required for a job providing that a reasonably fit person is available.; Using a cement mixer - this is generally suitable where between about ¼m³ and 2m³ of concrete is required. It will require continuous mixing of loads and normally ...
