Dec 17 2020 the volume of coarse aggregates required for rcc work 084 × 5054 cum ÷ 1 cum 4245 cum ie 14991 cu ft note the value ie directly added above is taken from calculating the quantity of materials in different grades of concrete now we will sum up the total quantity of cement sand aggregates required for the compound
Feb 06 2017 concrete mix design 22 3 mixing water content slump 50 mm maximum size of aggregate 20 mm concrete is non airentrained 23 concrete mix design 23 24 concrete mix design 24 the mixing water content is 185 kgm3 of concrete the approximate entrapped air content is 2 the required cement content 185047 394 kgm3
For the calculation of water quantity for concrete first of all we have to find the quantity of cement just assume that the required volume of cement for the mix is 100 kg and wc is 04 water quantity watercement ratio x volume of cement water quantity 04 x 100 kg 40 liters 100 kg cement or 20 liters 50 kg cement
If we need to calculate water quantity for concrete first find the cement content for the volume if we assume the required cement volume as 50kg required amount of water wc ratio x cement volume therefore required amount of water 05 x 50 kg 25 litres 50 kg cement
In m20 mix there is 3 part of aggregate quantity volume of aggregate355×dry volume in cft volume 355×1817×353147 cft volume 34960 cft if market rate of aggregate is is 70 rupees per cft then total cost of aggregate total cost rs 70×34960 rsrs 24472 34960 cuft of aggregate quantity is required for 1000 square feet 5 inch thick rcc slab in india and their construction cost is around rs
In order to restrict the maximum water content per cubic meter of concrete to 190 litre considering the guidelines as suggested in irc44 is 10262 for 20 mm maximum size of coarse aggregate and greater fineness of available cements wc ratio may be selected as 050 for 360 and 380 kg cement per cubic meter of concrete and 045 for 400 and 420 kg cement per cubic meter of
In this method fine aggregate quantity is fixed irrespective of cement and coarse aggregate proportions hence the quality of concrete mix will be varied and required strength may not be obtained in nominal mix design watercement ratio also not specified grades of concrete m20 and below are prepared by the nominal mix
