How to determine concrete yield
pounds in the lightweight aggregate—a total of 200 pounds or 24 gallons of extra water. Only about 12 additional gallons of water would be needed to produce the re q u i r ed 4inch slump. In terms of yield, we would end up with a batch totaling 25 cubic feet rather than 27—a loss of 8 perc e n t . Although the effect of aggregate moisture ...

06/03/2020 · The PCC If we are using roundshaped aggregate, the flowability of the concrete will rise. However, the loadcarrying compressive strength of concrete may decrease dramatically, it contact amongst the roundshaped aggregates will be minimal. When resistance would occur in the angular aggregate, increasing the ductility. As a result, angular ...
Aggregates
Aggregates. Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the ...

Fineness Modulus of Aggregates: The Inside Scoop
An example provided in the ACI 211 standard states that, "For a fine aggregate having a fineness modulus of and a nominal maximum size of coarse aggregate, the table indies that of coarse aggregate, on a dryrodded basis, may be used in each cubic meter of concrete. The required dry mass is, therefore, x 1600 = 1,136kg."

2. Coarse Aggregates. The coarse aggregate used in PCC Concrete should be pieces of good quality granite, and hard, durable aggregate. In addition, it should be free from dust, dirt, and other solids. The size of the broken stone should be smaller than 20 mm. Coarse Aggregates used for PCC Concrete should be retained in a 5 mm square mesh.

The beams are monitored twice a week for changes in length, weight and sonic modulus. A loss of more than 20% sonic modulus, in 300 cycles, is considered a failure. Beams are removed from the freezer if the sonic modulus dips below 60%. Three pcc beams are made from each aggregate sample submitted for testing.
