How to Calculate Quantities of Cement, Sand and Aggregate

Feb 07, 2017 · One bag of cement and other ingredients can produce = 400/2400 = 0.167 Cum of concrete (1:2:4) 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

What are the Correct Concrete Mixing Ratios - Ratio Chart

Some basic mixing ratios for concrete are 1:2:3, 1:3:3, 1:2:4. These mixing ratios are based on the proportions of cement : sand : stone in that order. The ratio you use will depend on what psi strength you need. To make concrete there are four basic materials you need: Portland cement - …

Concrete Mixing Methods and Concrete Mixers: State of the Art

2.1.2 Pan Mixers All pan mixers work on basically the same principle [3]: a cylindrical pan (fixed or rotating) contains the concrete to be mixed, while one or two sets of blades rotate inside the pan to mix the materials and a blade scrapes the wall of the pan. The shapes of the blades and the axes of rotation vary. Figure 4 shows the different

water) and contains 1100 pounds of fine aggregate and 2000 pounds of coarse aggregate. The mix design shows fine aggregate absorption to be 2% and coarse aggregate absorption to be 1%. The batch plant operator measures the aggregate moisture and finds that the fine aggregate moisture is at 5%. The coarse aggregate, just delivered, has a

Concrete Batching - an overview | ScienceDirect Topics

Over a 6-month summer/autumn period, the energy consumption and production levels of six different concrete-batching plants were audited. The average CO 2 emissions due to batching per cubic meter of concrete produced were found to be 0.0033 t CO 2-e/m 3.
