Aggregates for Concrete as per American Standards - ASTM PDF
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 .
Concrete Aggregates: Effects and Classifi ion Civil
Coarse aggregate: Aggregates predominately retained on a No. 4 4.75-mm sieve are classified as coarse aggregate. Generally, the size of coarse aggregate ranges from 5 to 150 mm. For normal concrete used for structural members such as beams and columns, the maximum size of coarse aggregate is about 25 mm.
Classifi ion of Aggregate Based on Size, Shape, Unit weight
The classifi ion of Aggregate is generally based on their geological origin, size, shape, unit, weight, etc. Aggregate is the major ingredient of concrete. Aggregate is derived from rocks. They are broadly divided into two egories i.e. fine and coarse aggregates. Their properties depend on the mineralogical compound of racks.
Aggregate Classifi ion and Test on Aggregate - Civil
In the construction industry, aggregate are used as filler material in the production of concrete and mortar. Aggregate occupy around 70% to 80% of the volume of the concrete, reduce shrinkage effects and minimize costs. The coarse aggregate form the main matrix of concrete and the fine aggregates form the filler matrix between the coarse
Different Types and Sizes of Aggregate for Concrete
Glass aggregate can replace part or all of the sand and gravel in concrete, for effects that range from colorful terrazzo, to granite- or marble-like finishes, to concrete that reflects light like a mirror. Glass aggregate can even be used to produce concrete that literally glows. SLAG AGGREGATE
