Different Types & Sizes of Aggregate for Concrete

Aug 11, 2018 · Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete. Larger aggregate diameters reduce the quantity of cement and water needed because of its lower Voids. When the aggregate is sieved through 4.75mm sieve, the aggregate retained is called coarse aggregate.

Fineness Modulus - an overview

This system was based on percentage passing the 600-μm sieve but gave broadly the same results as the current European C, M, and F categories. Generally, within the permitted standard limits, the grading of fine aggregate has a greater influence on the properties of concrete than that of coarse aggregate.

Classification of Aggregates Based on Size

The size of the aggregate bigger than 4.75 mm is considered as the coarse aggregate i.e. basically, all other aggregates which are retained on 4.75mm IS sieve while sieve analysis is performed. According to sources of coarse aggregates, it can be further classified as: (a) Uncrushed Gravel or Stone: It results from natural disintegration of rock.

gradation of aggregate for concrete block

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.
