Properties of Aggregates Civil Snapshot

For the preparation of economical concrete mix on should use largest coarse aggregates feasible for the structure. IS-456 suggests following recommendation to decide the maximum size of coarse aggregate to be used in P.C.C & R.C.C mix. Maximum size of aggregate should be less than. One-fourth of the minimum dimension of the concrete member.

Classification of Aggregates Based on Size and Shape

Coarse Aggregate. Gravel, cobble and boulders come under this category. The maximum size aggregate used may be dependent upon some conditions. In general, 40mm size aggregate used for normal strengths and 20mm size is used for high strength concrete. the size range of

The Specific gravity of coarse aggregate was determined as 2.309. It was 13% reduce from standard value 2.67 which is in the range from 2.5 to 3.0. The Specific gravity of fine aggregate was also accurate. Aggregate Crushing value test: This test was performed as per IS: 2386 (Part IV) 1963. The crushing value of RCA was 20%.

Strength of Coarse Aggregates

While we talk about the strength of coarse aggregates it refers to the crushing strength of the aggregate itself. However, the required information on strength of coarse aggregates can be obtained from indirect tests: crushing strength of prepared rock samples, crushed value of bulk aggregate, and performance of aggregate in concrete.

To Determine Crushing Strength of given Aggregate

To Determine Crushing Strength of given AggregateConcrete Practical Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar.

7 Lab Test on Aggregate Should Satisfy for Use in Concrete

Crushing Test on Aggregate The crushing test on aggregate gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. If the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate.

Effect of Aggregate Properties on the Crushing Strength of

consideration of size (a) coarse aggregate (b) fine aggregate. The size of aggregate bigger than 4.75 mm is considered as coarse aggregate and aggregate whose size is 4.75 mm and less is considered as fine aggregate [6]. The strength, durability and structural performance of concrete are

How to Determine the Aggregate Crushing Strength Value in

Effect of recycled coarse aggregate on concrete

Jun 22, 2011· Effect of recycled coarse aggregate on concrete compressive strength. For this purpose, 30 mix proportions of concrete with target cube compressive strength ranging from 20 to 60 MPa were cast with normal coarse aggregate and recycled coarse aggregate from different strength parent concretes. Results of 28-d test show that the strength of different types of recycled aggregate affects

Aggregate Crushing Value Test Determine Aggregate

Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength. Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical performance.

To Determine Crushing Strength of given Aggregate

To Determine Crushing Strength of given AggregateConcrete Practical Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar.

Functions Of Fine & Coarse Aggregate in Concrete Civil

It assists the cement paste to hard the coarse aggregate particles. It helps to prevent possible segregation of paste and coarse aggregate particularly during the transport operation of concrete for a long distance. It reduces the shrinkage of binding material. It prevents the development of a crack in the concrete.
