However, the availability of good quality aggregate is still a problem, mainly due to the strict environmental laws that restrict mining. The global aggregates market size was valued at $ 432.5 billion in 2018 and is expected to grow at a CAGR of 6.5 per cent from 2019 to 2025. In India, the demand for aggregates will arise from residential and commercial construction as well as large-scale smart city projects funded by the government.

Major policy announcements by the government in the past have given a lot of impetus to the infrastructure industry in India, with announcements and commencement of Aatma Nirbhar Bharat, major road projects viz, Bharat Mala project, dedicated railway freight corridors, smart city, metro projects, housing and infrastructure projects that have been the key drivers for the growth of infrastructure sector in the country. Had it not been for the pandemic situation, the total investments in the infrastructure sector in the country would have crossed $100 billion per annum. While it is difficult to give a consolidated figure on the total aggregates produced in the country, it is imperative for infrastructure investment to continue so that the industry continues to be a major growth driver for the Indian economy.

What is the current aggregate and M-sand production scenario?
As per the sand mining framework released by the Ministry of Mines in March 2018, India has 178 M-sand units—of which 164 are in Karnataka alone—that produce 32 million tonne a year.

Road projects including NHAI and PWD projects have resumed in the country amidst the ongoing COVID-19 crisis across nation. The government allowed the resumption of work on 260 projects out of a total 375. However, owing to the migrant worker crisis and slowing up of demand, growth has been impacted. The moratorium announced by the government to all the businesses across the country has given temporary relief to the ongoing liquidity crisis.

While the demand for newer machines is not that bullish the existing population of machines is fully optimised to undertake current developmental activities in mining and infrastructure. The biggest challenge for new equipment sale is the over leveraged balance sheet of many infrastructure companies, reluctance of NBFCs to fund due to poor CIBIL score of contractors and RBI’s tight guidelines for banking and finance sector.
