The modern digital world is creating a tremendous increase in the production of electronic waste , .E-plastic waste can be used as a fragmentary substitute for the coarse or fine aggregates in the construction industry , .Due to the high cost of transport and its effects on the total cost of production, the use of electronic waste cannot be considered as cent percent ...
It is worth noting that if proportioned correctly, fine sand can be utilized with success and its use is economical as it is available locally in desired quantity. Grading of Coarse Aggregate The requirements of I.S. 383-1970 for the grading of coarse aggregate are reproduced in Table 4.2 and for all in aggregate in Table 4.24.
Coarse aggregates consist of gravel, crushed stone or recycled concrete with particle sizes of ranging from 38-inch to 1.5 inches. Coarse aggregates are used in a wide range of construction applications, notably in concrete and asphalt mixes. Common uses for coarse crushed stone. Concrete aggregate.
2.2 Coarse Aggregate -- Aggregate most of which is retained on 475-mm IS Sieve and containing only so much finer material as is permitted for the various types described in this standard. NOTE -Coarse aggregate may be described as a uncrushcd gravel or stone which results from natural disintegration of
cement, aggregates, water, etc. which are economically available. Concrete is a composite material composed of granular materials like coarse aggregates embedded in a matrix and bound together with cement or binder which fills the space between the particles and

In this article, you will get to know all about coarse aggregates, classification of coarse aggregate, properties of the coarse aggregates and the different tests which are performed on the Coarse Aggregates.
What is the need for a suitable coarse aggregate. In-world, our construction industry needs 200 million cubic meters approx of concrete every year , In which total aggregate is 70 per cent, meaning 140 million cubic meter aggregate is required every year. And as the village of developing countries develops, the need will increase further.
1.Size of Coarse Aggregates The size of the coarse aggregate depends on the use of the concrete is to be poured. For large-scale concreting operations without complex reinforcement, large aggregates of size 80 mm, 40 mm, 20 mm are used. For the simple construction of residential or other buildings, 20 mm is the maximum size will be used.
