01/09/2018Aggregates are used to give body and strength to a concrete or mortar mix Coarse aggregate is small stones usually less that 20 mm in diameter and fine aggregate is basically sand Sharp Sand (which has larger grains) is used for concreting or laying paving slabs and Soft Sand is used for bricklaying etc It is also possible to buy mixed Get Price

Fine Aggregate Definition Size Density and Properties

Fine aggregate is the essential ingredient in concrete that consists of natural sand or crushed stone The quality and fine aggregate density strongly influence the hardened properties of the concrete The concrete or mortar mixture can be made more durable stronger and cheaper if you made the selection of fine aggregate on basis of grading zone particle shape and surface texture abrasion Get Price

Aggregate Properties

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 When determining the strength of normal Get Price

What is the role of aggregates in concrete?

01/12/2017Aggregate's impact on different characteristics and properties of concrete is certainly huge The significant reality is that some of 70-80% of the amount of concrete volume is taken by the aggregates itself It is therefore significantly importan Get Price

What is No

Can Changes in Fine Aggregate Affect Concrete

Concrete made with a fine sand (low fineness modulus) has much higher paste requirements for good workability ASTM C 33 Standard Specification for Concrete Aggregates requires that the fineness modulus not vary by more than 0 2 from the value used for mix design purposes If it does vary by more than 0 2 changes in the mix proportions are Get Price
