Active calcium silicate market is primarily driven by robust growth in the construction industry. The construction segment is one that has found rapid growth in the developing and underdeveloped economies, while also growing steadily in the developed ones. Construction spending in the United States crossed USD 1.29 trillion in 2018, while the global construction costs as a whole, are expected to rise on an average by 4.3% in coming years. The compound has a wide application scope owing to its dynamic nature, and it is extensively utilized in the manufacturing of acoustic tiles and wallboards to provide sound proofing and protect from fire.
Active calcium silicate is a poly-silicate compound that is produced by making use of various raw materials such as limestone, sodium silicate and hydrochloric acid. It is used in various application segments, on account of its desirable technical properties such as sound absorption and high-temperature resistance. It is widely available in the form of blocks, powder, and boards. Active calcium silicate is a safer alternative to asbestos in high temperature insulation applications. The key application segments include ceramics, fire protection, cement, paints & coatings, and insulation.
Construction Sector — A Major Customer
Increasing government spending on industrial, commercial, and residential construction development has positively impacted the global market growth of active calcium silicate. It is widely utilized in various application segments owing to its characteristics such as excellent adhesion, intumescence, and fire resistance. The construction industry needs to follow the regulatory standards that are implemented by regulatory bodies like OSHA and NIOSH, which ask for builders to implement additional security features in buildings.
Residential building fires are still a major cause of death in the United States. According to 2018 FEMA data, an estimated 379,600 residential fires took place in the country that year, which resulted in close to 2,800 deaths. Moreover, such incidences also cause great financial losses, and this figure stood at 8.19 billion in 2018. As such, fire protection becomes a major task on hand for the authorities, and the desirable properties of active calcium silicate in combating such hazards has provided impetus to the market.
Insulation segment dominated the global active calcium silicate market owing to increasing demand from high-temperature applications such as glass, petrochemical, and steel. In addition, it is widely used in oil refinery, building walls, blast furnace, and electric arc furnace in boards and blocks form. Use of active calcium silicate is also important in the ceramics sector, which is growing at a rapid pace on account of the emergence of 3D printing technology, as well as its application in dental implants.
Europe dominated the global market in terms of volume and revenue in 2016 and is expected to continue its domination over the years ahead. Europe is followed by Asia Pacific, which is expected to witness robust growth in the coming years, especially in the construction sector, with economies such as India and China leading the way in regional infrastructural development. The demand for active calcium silicate from various application segments is propelled by a positive outlook from construction industry owing to its importance in acoustic insulation, and presence of regulatory standards imposed by various regulatory bodies.

Further key findings from the study suggest:
- In January 2020, HIL Limited approved the sale of their calcium silicate insulation products division, with the brand ‘HYSIL’ to be transferred into the hands of Calderys India Refractories Limited. Calderys is a wholly-owned subsidiary of the France based multinational company Imerys S.A.
- In November 2019, Johns Manville announced that it had signed an agreement that concerns the acquisition of ITW Insulation Systems, which is known for its premium, low-temperature polyisocyanurate foam insulations and metal jacketing solutions. The company has four manufacturing plants (2 each in U.S. and Canada). Through this acquisition, Johns Manville would be focusing on the cold and cryogenics market.
- In September 2018, scientists at Rice University successfully developed micron-sized calcium silicate spheres which could possibly lead to stronger, greener concrete. This work built upon the previous project by the same team that developed self-healing materials with porous, microscopic calcium silicate spheres.
