Volume of 01 bag (50 kg) of cement = 50 X 0.000694 = 0.035 cubic meter (cum) Since we know the ratio of cement to sand (1:2) and cement to aggregate (1:4) Volume of Sand required would be = 0.035*2 = 0.07 cubic meter (cum) Volume of Aggregate required would be = 0.035*4 = 0.14 cubic meter (cum)

Learn MoreConsider the design of a wastewater treatment plant (WWTP) for a community with average daily and peak hourly wastewater design flows of 2.0 MGD and 5.0 MGD. The raw sewage has an average of 230 mg/L BOD5 and 260 mg/L of suspended solids. 1. After screening and grit removal, the WW is to be treated by primary sedimentation in two

Learn MoreA loft apartment, on the other hand, refers to a large adaptable open space, often a former industrial building or other type of space converted for residential use. This freedom in terms of design and adaptability has resulted in some very beautiful and amazing loft designs. We have selected 10 of the most impressive ones. 1.Vertical Loft.

Learn MoreVolume Fun Facts. There are 54 50lb bags of stone or sand per cubic yard. 27 cubic feet equal 1 cubic yard (3'L x 3'W x 3'H). Soil weighs about 2,200 lbs per cubic yard. Stone weighs about 2,700 lbs per cubic yard. Mulch weighs 250-750 lbs per cubic yard. Full size pick-up with 8' box a heaping load is 3 cubic yards.

Learn MoreLarge Batches of Concrete Mixes. 15 Mpa This is a low-strength concrete mix and is suitable for house foundations that are not reinforced, and for boundary walls and freestanding retaining walls.. To make 1 cubic metre of 15 Mpa concrete you will need to mix 5 1/2 bags of cement with 0,75 cubic metres of sand and 0,75 cubic metres of stone.

Learn MoreBoth of these concrete calculators make an allowance for the fact that material losses volume after being mixed to make concrete. Calculator are provided for a general mix and a paving mix, the different ratio of materials are: General mix - 1:5 cement:all-in ballast or 1:2½:3½ cement:sharp sand:gravel. Paving mix - 1:3½ cement:all-in

Learn MoreMany plants, in an aquaponic system, prefer a pH closer to 6.0, and since the fish and plants share the same water, a pH level of 6 or 7 (point) something becomes the ideal. We've seen some ponds that due to their construction and alkalinity, rapidly creep to about 8.4, and stay there, no matter how many times the water is treated back down

Learn MoreAll concrete is estimated in cubic yards (one cubic yard = 27 cubic feet). For large concrete jobs - four cubic yards or more - the concrete should be delivered by a ready-mix truck. It's also possible to haul fresh concrete to your site in special two-cubic-yard trailers provided by concrete producers.

Examples of how each t o l e r ance affects the batch we i g h t s of a typical 3500-psi concrete mix also are show n . • Cementitious materials - 1% (5 pounds of cement per cubic yard)

Learn More5. Cover the wire mesh with another layer of concrete and smooth it with a trowel. Pour or shovel another 2 in (5.1 cm) of concrete over the chicken wire. Use a hand trowel to smooth it out evenly. 2 in (5.1 cm) is the recommended thickness for the concrete so it holds up against cracking over time.

Learn More2.1 DESIGN REQUIREMENT OF CONCRETE (I. S. I) In water retaining structure a dense impermeable concrete is required therefore, proportion of fine and course aggregates to cement should be such as to give high quality concrete. Concrete mix weaker than M20 is not used. The minimum quantity of cement in the concrete mix shall be not less than 30
