what is m sand? - source, properties & advantages [civil,the m sand is perfect for construction, and it is classified into three types based on its construction activity. types of m sand. m sand for concrete – the particle size above 4.75 mm will be used only for concrete as per is code 383. p sand – this type of sand is mainly used for plastering work in which particle sizes are less than 2.3 mm.how to estimate the quantity of sand and cement required,if 0.46728 m 3 of sand is required to make 35 blocks, therefore, 41 m 3 of sand (about 67.60 tonnes assuming the density of dry sand = 1600 kg/m 3) is needed to make 3000 blocks. for a 5 tonne tipper of 3.8 m 3 capacity, we have to order for 11 trips of sharp sand..

m-20 = 1 : 1.5 : 3 = 5.5, (cement : sand : aggregate) some of mix is – 5.5. where, m = mix 20 = characteristic compressive strength. consider volume of concrete = 1m3. dry volume of concrete = 1 x 1.54 = 1.54 m3 (for dry volume multiply by 1.54) now we start calculation for find cement, sand and aggregate quality in 1 cubic meter concrete
let’s take dry mixture of aggregate sand and cement required is 1.52 cubic meter. m20 have an approximate proportion of cement sand and aggregate is 1:1.5:3 cement in bag = (1/5.5.)x1.52/0.035 =7.89 say= 8 bags
(this is wet volume that means we need this much volume of cement mortar after mixing water, so for dry volume, we have to add 30-35% as bulkage of sand, we are using 35% and wastage as 20%) consider 35% sand bulkage = 1.2 m 3 x (1+0.2+0.35) (many of us would use 1.54 as constant)
= 100 m 2 x 0.012m = 1.2 m 3 (this is wet volume of cement mortar (after mixing water) but we need dry volume. to get dry volume consider 35% bulking of sand and 20% wastages = 1.2 m 3 x (1+0.2+0.35) (rather than 35% sand bulkage and 20% wastage you can add 1.54 as constant) = 1.86 m 3
dear sir please give me the no of bricks and cement bag number to construct 7.65*7.65*1.8 m and wall thickness is 0.23m early response in this regard is highly appreciated like like
1 cement 2.5 sand 4 aggregate is ok for fence posts. 13bags of cement per cubic metre. the more cement the more costly of course so don’t over do it. note: these are 20kg bags of general purpose cement. ← prev: cisco ssl vpn using openconnect demonstration video next: fedora 16 screen flicker →.
manufactured sand, pond ash and slag sand are some of the alternatives, whose behaviour when used in cement composites are not very much clear. m-sand is artificially manufactured fine aggregate obtained from a source material, purpose designed for use in concrete and mortar or for other specific products such as blocks.
now question is how much cement sand and aggregate required for 1 cubic metre of m15 concrete? their ans will be following ans. 6.34 bags (0.22 m3, 317 kgs) cement, 20 cft (0.44 m3, 713 kgs) sand & 39 cft (0.88 m3, 1364 kgs) aggregate are required for 1 cubic metre of m15 concrete.
no. of bags required for 01 cum of concrete = 1/0.167 = 5.98 bags ~ 6 bags. from above, if the concrete mix is 1:2:4 , to get a cubic meter of concrete we require. 1.cement = 6 bags = 300 kgs. 2.fine aggregate = 115/0.167 = 689 kg. 3.coarse aggregate = 209/0.167 = 1252 kg. 4.water = 300/0.55 = 165 kg.
now question is how much cement sand and aggregate required for 1 cubic metre of m10 concrete? their ans will be following ans. 4.5 bags (0.154 m3, 222 kgs) cement, 21 cft (0.462 m3, 998 kgs) sand & 40.5 cft (0.924 m3, 1432 kgs) aggregate are required for 1 cubic metre of m10 concrete.
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.
hence 15.08 cft of sand and 30.16 cft of aggregate is requied to prepare one cubic meter of m20 grade concrete. cement, sand and aggregate required for different grades of
480 kg of cement, 720 kg of sand and 1200 kg of aggregate are offered for 1 cubic meter of concrete. the mass of one cubic meter of concrete is about 2400 kg. one cubic meter of concrete is calculated as 2400kg: cement = 2400 × 2 ÷ (2 + 3 + 5) = 480 (kg); sand = 2400 × 3 ÷ (2 + 3 + 5) = 720 (kg);
therefore, we need 10.5 bags of cement, 0.5454 m 3 of sand, 1.09 m 3 of coarse aggregates and 163.62 litres of water. concrete ingredients calculator hope you enjoyed the content.
8 bags of cement required for 1 cu.m of m20 grade concrete. 672 kg of sand required for 1 cu.m of m20 grade concrete. 1326 kg of 20mm aggregate is required for 1 cu.m of m20 grade concrete. 200 litres of water is required for 1 cu.m of m20 grade concrete. table for quantity of cement, sand, aggregate, water required for different grades of concrete :-
volume of concrete = (1 cement part)/5.5 + (2 sand part)/5.5 + (4 coarse aggregate part)/5.5) therefore volume of cement = 1/5.5 x 1.55 (bulkage & wastage) volume of sand =1.5/5.5 x 1.55. volume of coarse aggregate = 3/5.5 x 1.55. so the required cement volume – 0.282 m 3 or 8.14 bags sand volume – 0.423 m 3. coarse aggregate – 0.845 m 3
cement is much more expensive than sand or gravel. for this reason, the amount of sand and gravel or aggregates in the concrete is maintained at around 60 to 80 percent of the total volume. however, the quantities used to affect the product. the more aggregate used in the more rigid mixture that concrete becomes. the less aggregate used, the soupier the concrete becomes. other mixes
however for nominal mixes we can use 1:2:4 for rcc here it is 1 part of cement, 2 parts of sand and 4 parts of aggregate so based on the size of the measuring boxes you can calculate the volume of materials required for one cubic meter of concrete.
8.064 bags of cement required for 1 cu.m of m20 grade concrete. 630 kg of sand required for 1 cu.m of m20 grade concrete. 1260 kg of 20mm aggregate is required for 1
cement : sand :: 1:1.5. quantity of sand =quantity of cement x 1.5. quantity of sand = 0.28 x 1.5 =0.42 m³. or quantity of sand =( 1.5/5.5) * 1.54= 0.42 m³. 1 m³=35.3147 cubic feet (cft) quantity of sand = 0.42 x 35.3147 = 14.832 cft. weight of sand = volume x density, density of sand = 1650 kg/m^3 weight of sand= 0.42 x 1650= 693 kg (0.693 tonnes)
cement = 8.25 bags/cum of concrete sand = 13.68 cft/cum aggregate = 27.34 cft/cum. b. the nominal mix proportion by volume for m45 would be 1:1.35:2.7. the approximate quantities are cement = 9 bags/cum of concrete sand = 13.24 cft/cum aggregate = 26.5 cft/cum. hope it helps. note :post questions/queries in our forum https://happho.com/questions/

example let suppose we have a two way slab having a length of 20 feet and same as width of 20 feet and use m-15 grade of concrete, calculate the quantity of cement ,sand and aggregate that are used in a slab and thickness of the slab is 6 inches?
the proportions of materials (cement, sand, coarse aggregate) for nominal mix/design mix concrete that are normally used are 1:3:6 or 1:4:8. as strength. rcc or reinforced cement concrete is strengthening of cement concrete by adding mild steel bars in it. there are two types of steel bar; round and torsion.
