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

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 moisture content of 0.5%. The operator computes the add-water as follows: Fine aggregate = 1100 lbs x (0.05 – 0.02) = + 33 lbs Coarse aggregate = 2000 lbs x (0.005 – 0.01) = - 10 lbs

Coarse aggregates are any particles greater than 0.19 inch but generally range between 3/8 and 1.5 inches in ...

weaknesses in coarse aggregates. Service records are invaluable in evaluating aggregates. In the absence of a performance record, the aggregates should be tested before they are used in concrete. The most commonly used aggregates—sand, gravel, crushed stone, and air-cooled blast-furnace slag—produce freshly mixed normal-weight

Aggregate Sizing Explained. The term "aggregates" as used in the construction industry is a broad category of coarse and fine particulate material including sand, gravel, crushed stone, slag, recycled concrete, and geosynthetic aggregates and are actually the most mined materials in the world. Aggregate serves as a reinforcement to add ...

Fine Aggregates: They are the aggregate particles that pass sieve #4 but retain on sieve #200. Fine aggregates include a wide range of particle sizes. Specifically talking about sands, the grain-size distribution further classifies sand into coarse sand, medium sand, and fine sand.

Fine aggregate; Coarse aggregate; Fine Aggregate When the aggregate is sieved through a 4.75mm sieve, the aggregate passed through it called fine aggregate. Natural sand is generally used as fine aggregate, silt and clay also come under this category. The soft deposit consisting of sand, silt, and clay is termed as loam.

Fig 1: Aggregates used in production of concrete. The aggregates are broadly classified into two types based on the size, namely- fine aggregate and coarse aggregate. In this article, we discuss the properties of the standard aggregates used in the production of concrete as per the American Standards (ASTM- C33/C33M).

Coarse aggregates are any particles greater than 0.19 inch, but generally range between 3/8 and 1.5 inches in diameter. Gravels constitute the majority of coarse aggregate used in concrete with crushed stone making up most of the remainder. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed.

Aggregates Are Mainly Classified into Two Categories: Fine aggregate; Coarse aggregate; The fine aggregate is natural sand that has been washed and sieved to remove particles larger than 5 mm, and the coarse aggregate is a gravel that has been crushed, washed and sieved so that the particles vary from 5 to 50 mm in size.The fine and coarse aggregate is delivered separately.

1.Size of Coarse Aggregates: The size of the coarse aggregate depends on the use of the concrete is to be poured. For large-scale concreting operations without complex reinforcement, large aggregates of size 80 mm, 40 mm, 20 mm are used. For the simple construction of residential or other buildings, 20 mm is the maximum size will be used.
