Concrete is a material comprised of a number of coarse aggregates (particulate materials such as sand, gravel, crushed stone, and slag) bonded with cement. Cement is a substance that is used to bind materials, such as aggregate, by adhering to said materials, then hardening over time.
Construction Aggregate Calculator Enter the width, length, thickness, and product density and hit the "Calculate" button to calculate your estimate. If you do not know the product density, use the optional density estimator* or contact a local sales representative.
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.
Determination of the unit weight of coarse aggregates in a compacted condition. This test method is applicable to aggregates not exceeding 15 cm (6 inches) in nominal size. The unit weight so determined is necessary for the design of a concrete mixture by the absolute value method.
The density of course aggregate is 1560 km/ m^3. The density ofsomething can be found by dividing the mass by the volume.
Dec 19, 2017· In this video we will see how to determine the loose and rodded bulk density of 20 mm aggregate and there by findinding out the voids of 20 mm aggregate,which is …
During the concrete mix design, when the aggregate is to be batched by volume or by weight, then it becomes necessary to know the mass of the aggregates that will fill the container of unit volume. If we know the bulk density of the aggregate material then we can easily determine the mass required to fill a unit volume container.

Sieve the aggregate using the appropriate sieves (80 mm, 40 mm, 20 mm, 10 mm, 4.75 mm, 2.36 mm, 1.18 mm, 600 micron, 300 micron & 150 micron) Record the weight of aggregate retained on each sieve. Calculate the cumulative weight of aggregate retained on each sieve.
SPECIFIC GRAVITY OF COARSE AGGREGATE AASHTO T 85 GLOSSARY ... In Portland Cement Concrete the specific gravity of the aggregate is used in calculating the percentage of voids and the solid volume of aggregates in computations of yield. The absorption
Density of aggregate may go higher if void spaces decreases. 5mm aggregate has more density when compared with 20mm size of aggregate Hence We require 1326Kg of 20mm aggregate for 1m 3 of Concrete.
To determine the bulk density and percentage voids of aggregate . Apparatus (I)Balance -A balance sensitive to 0.5% of the weight of the sample to be weighed .
Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate.
