Concrete mix design belongs to the method of determining the ratios of concrete mix in terms of proportions of cement sand and coarse aggregates As for instance a concrete mix of proportions 1 2 4 signifies that cement fine and coarse aggregate are in the ratio 1 2 4 or the mix comprises of one part of cement two parts of fine aggregate and four parts of coarse aggregate Get Price
All Answers ( 21) To determine the proportions you have to perform mix design for this you have to find out the sp gr of cement CA FA and water cement ratio type of exposure Maximum size of aggregate etc Once the W/C ratio is determined use 186 kg water (for 20mm CA) to find out the qty of cement per cum of concrete Then determine the qty Get Price
Feb 11 2019Concrete Calculation All 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 Get Price
