Aggregates - India

• 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
• Ready Mixed Concrete 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
