gradation of aggregate refers to the amount of each size,-grade b: these are also used as load bearing units and shall have a block density between 1100 kg/m3 and 1500 kg/m3. these shall be manufactured for minimum average compressive strengths of 3.5 and 5.0 n/mm2 respectively at 28 days-solid concrete block is classified as grade c--grade c: the solid concrete blocks are used as load bearing units and shall have a block density not less than 1800.with a ratio mix of 1:3:6, how many concrete blocks can be,a of :3:6 means that for every unit of you are using 3 units of sand and 6 units of aggregate. the amount of you can make will depend on the size unit of your mix and the size you intend to make..

what is the 1:2:3 mix ratio for concrete? the mix ratio of 1:2:3 consists of 1 part cement, 2 parts sand, and 3 parts stone (plus some water) to make a concrete mix you can use for most any building project. the way you measure the ratio could be in shovels, buckets, or wheel barrows. as long as you're consistent you'll get a good strong mix.
= 1.5 bags. sand: sand: = (dry volume x ratio x 35.3147)/sum of ratio. (1 cum = 35.3147 cubic feet.) = (0.2527 x 4 x 35.3147)/5 = 7.1 cubic feet. conclusion: bricks = 526. cement = 1.5 bags. sand = 7.1 cubic feet. note: these ratios may change by changing the dimension of the mortar thickness or size of the bricks as well as the mortar ratios 1: 4, 1: 6 etc.
today we will discuss how to calculate quantities of materials for different mix ratio of concrete. (dry mix method) we will calculate quantities of materials for 1 m3 concrete (by volume). let us assume the mix proportion is 1 : 2: 4 (cement:sand:stone =a:b:c) volume of wet concrete = 1 m3. volume of dry concrete = 1 × 1.54 = 1.54 m3.
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.

compressive strength table 3 and figures 1 and 2 show the result of the compressive strength for the different blend of laterite and quarry dust. the 28 day compressive strength ranges from 1.87n/mm2 to 2.56n/mm2 . these values are within the minimum 1.75n/mm2 specified by ) for load bearing sandcrete blocks.
consider volume of concrete = 1m 3 . dry volume of concrete = 1 x 1.54 = 1.54 m 3. aggregate = (3/5.5) x 1.54 = 0.84 m 3 ∴ 3 is a part of cement, 5.5 is sum of ratio. density of aggregate is 1500/m 3 calculation for kg = 0.84 x 1500 = 1260 kg. as we know that 1 m3 = 35.31 cft. calculation for cft = 0.84 x 35.31 = 29.66 cubic feet. also you can download excel sheet for calculate concrete volume (cement…
density of concrete = 2400 kg/cum. so, 1 bag of cement produces = 400/2400 = 0.167 cum. 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 =
a cubic meter of ready-made cement slurry, made in a ratio of 1: 4, requires the use of 4.1 centners of cement grade m500 and 1.14 cubic meters. m. sand. since 1 m3 of wall thickness of one silicate brick with dimensions of 25x12x6.5 cm consumes 0.24 cubic meters. m, the consumption of cement mortar per m3 is calculated by multiplying the specific consumption by 410.
typical mix ratio for mortar (laying of blocks) is 1:6. cement requirement quantity of cement required = 1/7 x 1440 kg/m 3 = 205.71 kg making allowance for shrinkage between fresh and wet concrete = 1.54 x 205.71 = 316.79 kg quantity of cement required in bags = 316.79/50 = 6.33 bags. for 4.5m 3 of mortar;

1. cement = 4086 pounds. 2. stone (3/4' and 3/8') = 13,270 pounds. 3. sand = 11970 pounds. this gives you a basic 3000 psi concrete mix ratio of: 1 part cement 3.25 parts stone 2.93 parts sand; rounded off it's basically a 1 : 3 : 3 mix ratio. if i break the weights down per yard of concrete it comes to: 1. cement = 510.75 pounds. 2. stone = 1658.75 pounds. 3.
here is a simple and effective brickwork calculation formula that will help you to understand how much bricks will be required for 1 cubic meter of brick masonry. we can divide the calculation into three parts to find out the amount of cement, sand, and bricks required. given that the thickness is 230 mm for 1 cum brickwork and the ratio for cement mortar for brickwork is 1:5. by putting these values in the formula we will be able to find out how to calculate cement

volume = volume of mortar x (ratio of cement/ sum of ratio) volume = 0.306565x (1/7) = 0.0438 bags = 0.0438 x 1440 = 63.06 kg. sand calculation. volume = volume of mortar x (ratio of sand / sum of ratio) volume = 0.306565x (6/7) = 0.2627 cft = 0.2627 x 35.31 = 9.27841. therefore- all materials required for 1 cubic meter brick is, numbers of brick-500
