- Aggregates include crushed stone,
gravel and sand.
- Production centers around
quarrying, preparing and sorting the raw material.
- Aggregates are mainly used
in the manufacture of ready-mix concrete, concrete products and asphalt
as well as for road building and railway tracks.
- The recycling of aggregates from
concrete demolition material is gaining in importance
- Roads will account for 15% of
India's infrastructure investment in the 11th plan with a targeted spend
of Rs 3, 19,200 crore. While India has one of the longest road systems
in the world, a very tiny fraction of this is comparable to world
standards in terms of width and quality
- RMC is made on demand and can be
transported to worksites by concrete mixer trucks. It eliminates need
for storage space for basic materials at site and consequent wastage. As
compared with the global construction market, in India, RMC accounts for
3% of the total concrete off take
- Concrete is the second most
consumed commodity by volume after water. One cubic meter consists of
approximately 300 kilograms of cement, 150 liters of water and 2 tonnes
of aggregates.
- Asphalt is a bituminous
construction material used primarily for road paving. By weight, asphalt
consists mainly of aggregates of differing grain size.
- The production of alternative
construction materials such as clay, flyash bricks, fly ash sand-lime
bricks, lightweight aggregates (sintered fly ash aggregate, bloated clay
aggregate, foamed slag,
etc.) and lightweight aggregate concreter masonry units, autoclaved
cellular concrete building units, pre-cast dense concrete building
blocks and roofing / flooring units, wood substitutes etc. should be
promoted
