Accommodation Times, is the only newspaper in India, which is shouting since decades to give ‘industry status’ to the building construction industry. But so far, nothing is being done in this regard. The government has granted industry status to the Indian Film Industry, but nothing is done for the basic housing construction industry. Housing construction industry in India is more than aRs 1000 crore industry providing employment to more than 25 million workers and paying whooping sums to the government and development charges to the government, as a  result there are no incentives to develop innovative materials like in other countries.

Some of them are as follows:

Self Healing Concrete: Cement is one of the most widely used materials in construction, but also one of the largest contributors to harmful carbon emissions. Cracking is a major problem in construction water usually caused due to water and chemicals. Researchers at Bath University are developing a self-healing concrete, using a mix containing bacteria with microcapsules, which will germinate.

Construction materials constitute about 40% of the project cost. Therefore it becomes necessary that the materials are used more efficiently. Even the selection of proper materials is as important as efficient use of the same. Innovation in respect of the materials should be done considering the requirements and suitability in construction and civil engineering activities have experienced a boom due to rapid improvement of building materials.

In 1990, The Central Government, took the initiative to set up the Building materials and Technology Promotion Council (BMTPC) to promote cost-effective, eco-friendly and energy efficient building materials and technologies. Some of the natural materials that were considered by BMTPC are 27 types of agro-industrial wastes, by products, residues, natural fibers, plantation timbers, including rice and wheat husk, biogases from sugarcane, coir, hemp etc.

Some of the Innovative Building Materials are:

  1. Super Plasticizers has resulted in production of pump able high-early strength concretes requiring minimum compaction.
  2. Replacement of sand and cement with pond ash/ fly ash in concrete production is one of the uses of waste products into a very useful material.
  3. Use of ductile rebars, a need based development of materials. These rebars have been developed to absorb the excessive stress generated during earthquakes. The rebars are having superior mechanical properties, better bond strength and improved ductility.

Materials used in construction should be such that these are accepted by the construction industry and the end user- Building Construction Material industry is expanding world over and materials used in the construction industry are so wide that truly sky is the limit.
