5 Green Building Materials To Watch Out For In 2019
Materials used in the construction industry are evolving constantly, not only to save costs and time but also to reduce their impact on the environment. Owing to the increasing concern about the environment and sustainability, many companies are offering building materials or solutions that are easy to use, versatile, don’t cause pollution, or don’t cause any harm to the existing resources. Here are the top 5 technological materials that will shape the future of the construction industry.
Precast concrete has the same durability and strength as regular concrete but is manufactured in controlled plants. This eliminates the need for casting on-site, shortens the installation time and reduces disruption to the site environment. By eliminating the need for on-site casting, it cuts down on transportation requirements and reduces a project’s carbon footprint. It also has higher thermal resistance and is an effective fire barrier.
Cross-laminated wood is made by laminating several small pieces of timber under high pressure in opposing directions. This makes the wood stronger and allows panels to be made to measure. The high strength of these wood panels can make them an effective substitute for steel and concrete. It has a lower carbon footprint and is an ecologically sustainable construction material. Since the panels can be made to measure off-site, it also speeds up the construction process.
This can be described as an iron-based alloy that contracts on heating and permanently pre-stresses a concrete structure in one go. This material could be a game-changer for the construction industry as it reduces construction timelines without compromising on strength and durability. It also saves space and equipment costs, thus proving to be more sustainable. Memory steel has the ability not only to revolutionize new construction projects but also the renovations of older structures.
Zero Carbon Cement
Cement is responsible for 5% of global carbon emissions. Efforts towards adapting the cement recipe for a sustainable future have led to the development of zero carbon cements. This mortar mix reduces the embodied CO2 considerably, without affecting the bonding strength of the material. A flexible fabric impregnated with concrete has also been developed. This fabric hardens on exposure to water. It uses 95% less material, is fire and water proof, durable, and can speed up the construction timelines.
Insulated Building Materials
With climate change in mind, thermal insulation has become an important part of new construction projects. This has led to the development of AAC blocks and block joining mortar that does not allow water and heat to penetrate through the walls. Thus the building materials themselves help keep a structure’s interiors cool and reduce the dependence on air conditioners etc.
All in all, the construction industry is moving towards building solutions that are not only easy to adapt, but also reliable, of superior quality and eco-friendly in nature.
