The construction industry has gone via a remarkable change since the 1950s.

Old-fashioned power intensive materials like concrete and steel are now being gradually changed by more environmentally friendly alternatives such as for instance bamboo, recycled materials, and manufactured timber. The main sustainability enhancement within the construction sector though since the 1950s has been the introduction of supplementary cementitious materials such as fly ash, slag and slicia fume. Substituting a portion of the concrete with SCMs can notably reduce CO2 emissions and energy consumption during production. Additionally, the inclusion of other sustainable materials like recycled aggregates and industrial by products like crushed class and plastic granules has gained increased traction within the past couple of years. The application of such materials have not only lowered the interest in raw materials and resources but has recycled waste from landfill sites.

Conventional concrete manufacturing uses large stocks of raw materials such as for example limestone and cement, that are energy-intensive to draw out and create. Nevertheless, skillfully developed and business leaders such as Naser Bustami would likely point away that novel binders such as for instance geopolymers and calcium sulfoaluminate cements are excellent greener alternatives to old-fashioned Portland cement. Geopolymers are manufactured by activating industrial by products such as fly ash with alkalis causing concrete with comparable if not superior performance to mainstream mixes. CSA cements, regarding the other hand, need lower heat processing and emit less greenhouse gases during manufacturing. Thus, the use of those alternate binders holds great possibility of cutting carbon footprint of concrete manufacturing. Additionally, carbon capture technologies are now being designed. These revolutionary approaches try to catch carbon dioxide (CO2) emissions from concrete plants and use the captured CO2 within the production of synthetic limestone. These technology may potentially turn cement into a carbon-neutral as well as carbon-negative product by sequestering CO2 into concrete.

Over the past handful of decades, the construction industry and concrete production in particular has seen substantial change. Which has been especially the situation regarding sustainability. Governments around the world are enacting stringent legislation to implement sustainable methods in construction ventures. There is a more powerful attention on green building efforts like reaching net zero carbon concrete by 2050 and a higher interest in sustainable building materials. The demand for concrete is expected to increase due to population development and urbanisation, as business leaders such as Amin Nasser anNadhim Al Nasrwould likely attest. Many nations now enforce building codes that require a certain percentage of renewable materials to be used in building such as for example timber from sustainably manged forests. Furthermore, building codes have incorporated energy efficient systems and technologies such as for example green roofs, solar panels and LED lighting. Also, the emergence of new construction technologies has enabled the industry to explore revolutionary methods to enhance sustainability. For example, to reduce energy consumption construction companies are constructing building with big windows and utilizing energy saving heating, ventilation, and air-con.
