Aggregates are a raw material intensively used in construction of roads, bridges, streets, bricks, concrete, and tiles. Every town and city and every road connecting them is built and maintained with aggregates. Aggregates are mixtures of sand, gravel, crushed rock etc widely used in construction, as a component of concrete, and in civil engineering work. Most aggregates come from land-based sources, and developers rely on the best quality sources to supplement demand and meet the construction needs.
Delivering high quality aggregate to the construction industry, is a great challenge and is at the foundation of all infrastructure progress. Large volumes of aggregates add to the value and support the local economy. They are also used to fill areas in ports and harbors or to reclaim land from the sea before the commencement of engineering works.
High-quality aggregate (granodiorite) is popular in the markets. Aggregate Industries are witnessing an increased demand from all spheres and they need to increase their annual production capacity by several million tones. Geological Surveys emphasize the importance of aggregates. In order to build houses it takes several tones. At present there is high activity in many sectors, with regards to infrastructure and housing work around the big cities.
The country is also performing at all-time-high levels, and there is a constant fuelling of demand owing to large infrastructure investments. The industry has witnessed large technological changes and has adopted new processes to meet the specifications of customers and dealers into operational level.
There is a stress to go for high quality products that are ideally suited to meet the customers’ needs. Moreover, what is required is a strong dealer network with excellent service support. The aggregate market holds lot of promise and is stable in production volumes. It has a very positive outlook for the business in 2017 as many infrastructure and real estate projects are going on.
The activity is expected to go forward, as there is a considerable backlog in housing capacity. There is also a continuation of meeting the demands of people and that tends to mean more infrastructure projects turning into new tunnels, railways, subways and roads, and this leads to enhanced capacity.
In many areas of rapid population growth, the infrastructure is always inadequate, and new roads, streets and sewage systems are required to be built to meet the expectations and increased needs.
most asphalt pavements are treated aggregates. The production of recycled aggregates, from concrete and asphalt pavements, has increased.
Replaced and reconstructed old roads and buildings have become a source of rich recyclable materials. In some applications, recycled aggregate has the potential to compete with newly mined aggregates on price and quality.
The production and utilization of natural aggregates is closely related to the population and the level of industrial development of an area. On an annual basis every person in the country requires 4.32 tons of crushed stone, 3.86 tons of sand and gravel 1/2 ton of cement.
During the past 20 years, per capita consumption of aggregates has increased by leaps and bonds. An estimated 38,000 tons of aggregates are necessary to construct a mile of lane of an interstate highway.
Construction of an average modern home requires 400 tons of aggregate.
Construction of an average size school or hospital requires 15,000 tons of aggregates.
In using it we must remember that in order to maintain or improve our standard of living, we need to use all mineral resources judiciously. We must understand the environment and preserve natural resources for future generations.
Companies must meet the requirements of environmental regulatory requirements at all levels.
