How to Calculate Cement, Sand and Aggregate The proportions of cement, sand, coarse aggregate and water plays an important role in determining the fresh and hardended properties of concrete. So care should be taken while calculating the amount of Cement, Sand and Aggregate required for 1 Cubic meter of Concrete.
Different proportion of cement and sand is used in mortar for different types of masonry work. For our calculating purpose, let’s assume we’ll use 1:4. That means, we’ll mix one part of cement with four parts of sand to prepare our mortar. The total part of ingredients is, = 1+4 = 5 . Calculating The Quantity of Cement. So, the quantity
Calculate Tons for Sand, Gravel or Limestone: Calculate Tons for Circles of Sand, Gravel or Limestone: Calculate Tons of Compacted Gravel or Limestone: Phone: 847-223-7000 Fax: 847-223-7067: Length in feet x Width in feet x Depth in feet (inches divided by 12). Take the total and divide by 21.6 (the amount of cubic feet in a ton).
01 bag cement yield = 0.167 cum concrete with a proportion of 1:2:4. 01 cum of concrete will require. Cement required = 1/0.167 = 5.98 Bags ~ 6 Bags. Sand required = 115/0.167 = 688 Kgs or 14.98 cft. Aggregate required = 209/0.167 = 1251 kgs or 29.96 cft
