Mar 23, 2015· For the same strength or workability, concrete with large size aggregate will require lesser quantity of cement than concrete with a smaller size aggregate. In a mass concrete work the use of larger size aggregate will be useful due to the lesser consumption of cement. This will also reduce the heat of hydration and the […]
Quality Counts. Make sure that your concrete producer purchases good-quality aggregate as verified by regular aggregate test results in compliance with ASTM C 33, "Standard Specifications for Concrete Aggregates." A history of good performance of a local aggregate also provides an indication of how well the material performs in service.
Concrete Technology Aggregates for Concrete Concrete Technology 27 Unit Weight of Aggregate in Bulk The Dry-Rodded Unit Weight of an aggregate is the weight required to fill a contained or a specified unit volume, after it has been rodded to attain maximum packing. ASTM C29 gives the common methods of determining the Dry-Rodded Unit Weight that
proportion select materials that, when properly mixed and properly placed, will produce an economical concrete mix that meets the requirements for placeability, consistency, strength, durability, and appearance. OBJECTIVE - The objective of this lesson is to learn how to select and proportion the materials for quality concrete.
sections and tables. However, the fact that aggregates satisfy ASTM C 33 or AASHTO M 6/M 80 requirements does not necessarily assure defect-free concrete. For adequate consolidation of concrete, the desirable amount of air, water, cement, and fine aggregate (that is, the mortar fraction) should be about 50% to 65% by absolute volume (45% to 60% ...
For Cement, Sand and Coarse Aggregate. This is a Volumetric Calculation. Assuming we need 2 m 3 of concrete for M20 Concrete Mix, (Mix Ratio, M20 = 1 : 1.5 : 3) Total Part of the Concrete = 1+1.5+3 = 5.5 Parts. Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume
