Aggregate The fines are sand and gravel or crushed stone is the coarse aggregate (10, 20 40mm) in most mixes. Admixtures in Concrete Accelerators added to the concrete to reduce overall setting times and gain early strength.
Aggregate is a process of combining separate objects to make one object or mass. A house, as an example is an aggregate of wood, insulation, nails, shingles, etc.
7. Estimation of coarse aggregate content The percent of coarse aggregate to concrete for a given maximum size and fineness modulus is given by Table 4. The value from the table multiplied by the dryrodded unit weight (the ovendry (OD) weight of coarse aggregate required per cubic foot of concrete).

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 .
4 How much does a kilogram weigh in Pounds? Convert Masses or Weights to and from metric units, British units {acres, townships, square miles, square feet, etc.}, scientific or nuclearsubatomic weights, archaic units, international units, and so forth.
The weight of gravel per cubic yard is approximately 2,970 pounds, or tons, if the gravel is dry. If the gravel is out of water, the weight per cubic yard is approximately 1,620 pounds or .81 tons. Comparatively, other building materials are much heavier or much lighter.
Following table shows unit weight of materials used at construction site. Please note this is for reference purpose only and may vary from place and type of material.
METHOD OF TEST FOR UNIT WEIGHT OF AGGREGATE CAUTION: Prior to handling test materials, performing equipment setups, and/or conducting this method, testers are required to read "SAFETY AND HEALTH" in Section H of this method. It is the responsibility of the user of this method to
While open graded coarse aggregate is often thought of as selfcompacting, this is not really the case. All open graded coarse aggregates, lightweight included, require some level of compaction to give the maximum stability and minimize settlement of the aggregate. 25
On Aggregate Grading ... size coarse aggregate used in this study.) If it didn't meet both requirements, we defined a combined aggregate as ... WG combined aggregate; and (b) NWG combined aggregate. Coarseness factor is the weight of the material retained above the 3/8 in. ( mm) sieve divided by the weight of the material ...
