The building and construction industry has gone via a remarkable transformation since the 1950s.

Conventional concrete manufacturing utilises huge stocks of raw materials such as limestone and cement, that are energy-intensive to draw out and create. However, industry experts and business leaders such as Naser Bustami may likely aim down that novel binders such as geopolymers and calcium sulfoaluminate cements are good greener options to old-fashioned Portland cement. Geopolymers are made by activating industrial by products such as fly ash with alkalis resulting in concrete with comparable if not superior performance to main-stream mixes. CSA cements, regarding the other hand, require lower temperature processing and emit fewer greenhouse gases during production. Therefore, the use among these alternate binders holds great possibility cutting carbon footprint of concrete manufacturing. Furthermore, carbon capture technologies are now being designed. These innovative methods try to capture carbon dioxide (CO2) emissions from cement plants and use the captured CO2 within the production of synthetic limestone. This technology could potentially turn concrete right into a carbon-neutral if not carbon-negative product by sequestering CO2 into concrete.

Old-fashioned power intensive materials like tangible and metal are now being slowly changed by more environmentally friendly alternatives such as bamboo, recycled materials, and engineered timber. The main sustainability improvement in the construction industry though since the 1950s is the inclusion of supplementary cementitious materials such as fly ash, slag and slicia fume. Substituting a portion of the cement with SCMs can dramatically reduce CO2 emissions and energy consumption during production. Moreover, the inclusion of other renewable materials like recycled aggregates and industrial by products like crushed class and rubber granules has gained increased traction within the past few decades. The usage of such materials has not only lowered the demand for raw materials and resources but has recycled waste from landfill sites.

Within the last number of years, the construction sector and concrete production in specific has seen considerable change. That is especially the case when it comes to sustainability. Governments across the world are enacting strict legislation to apply sustainable methods in construction projects. There is a stronger attention on green building attempts like reaching net zero carbon concrete by 2050 and a greater demand for sustainable building materials. The demand for concrete is anticipated to boost because of populace growth and urbanisation, as business leaders such as Amin Nasser an Nadhim Al Nasr would likely attest. Numerous nations now enforce building codes that need a certain percentage of renewable materials to be utilized in building such as for instance timber from sustainably manged forests. Moreover, building codes have included energy saving systems and technologies such as for instance green roofs, solar panels and LED lighting. Furthermore, the emergence of new construction technologies has enabled the industry to explore innovative methods to enhance sustainability. For example, to reduce energy consumption construction businesses are building building with big windows and using energy saving heating, air flow, and ac.
