EXAMPLE OF MIXTURE PROPORTIONING
We assume a slump of 50 mm without the plasticizer and a maximum of 200 mm to 250 mm with plasticizer. However, for proportioning purpose, we shall use 250mm ±20mm. Water content: In accordance with Table 9-5 or Fig 9-5, the required water content for a 50-mm slump, air-entrained concrete with 19-mm aggregate size is about 168 Kg/m3.
Designing and Proportioning Concrete Mixtures
The slump is specified at 25 mm to 75 mm. Use 75 mm ±20 mm for proportioning purposes. A 75-mm slump, air-entrained concrete made with 25-mm nominal maximum-size aggregate should have a water content of about 175 kg/m3.
The Effect of Aggregate Properties on Concrete
Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate.

Aggregate in Concrete - Concrete Network
Fine aggregate should fall within gradation limits provided in ASTM C 33, Section 6. If there is a deficiency in a locally available fine aggregate, concrete may benefit from the addition of air entrainment, additional cement, or a supplemental cementitious material (SCM) to address these shortcomings.
