As populations continue to increase and urban areas increase, the demand for concrete surge.

Conventional power intensive materials like concrete and steel are now being gradually replaced by more environmentally friendly alternatives such as bamboo, recycled materials, and manufactured timber. The primary sustainability enhancement in the construction sector however since the 1950s is the introduction of supplementary cementitious materials such as fly ash, slag and slicia fume. Replacing a portion of the cement with SCMs can somewhat reduce CO2 emissions and energy consumption during production. Moreover, the incorporating of other sustainable materials like recycled aggregates and industrial by products like crushed class and plastic granules has gained increased traction into the past few decades. Making use of such materials has not only lowered the demand for raw materials and natural resources but has recycled waste from landfill sites.

Over the past couple of decades, the construction sector and concrete production in specific has seen significant change. That is particularly the situation when it comes to sustainability. Governments across the world are enacting stringent rules to apply sustainable techniques in construction projects. There is a stronger focus on green building attempts like reaching net zero carbon concrete by 2050 and an increased interest in sustainable building materials. The interest in concrete is expected to increase due to population growth and urbanisation, as business leaders such as Amin Nasser anNadhim Al Nasrwould probably attest. Numerous nations now enforce building codes that require a certain percentage of renewable materials to be used in construction such as timber from sustainably manged forests. Furthermore, building codes have incorporated energy efficient systems and technologies such as for instance green roofs, solar power panels and LED lighting. Also, the emergence of new construction technologies has enabled the industry to explore innovative solutions to improve sustainability. For example, to reduce energy consumption construction companies are constructing building with large windows and using energy efficient heating, ventilation, and air conditioning.

Conventional concrete manufacturing employs huge stocks of raw materials such as for example limestone and concrete, which are energy-intensive to extract and produce. Nevertheless, industry experts and business leaders such as Naser Bustami would likely point out that novel binders such as for example geopolymers and calcium sulfoaluminate cements are excellent enviromentally friendly options to conventional Portland cement. Geopolymers are manufactured by activating industrial by products such as fly ash with alkalis resulting in concrete with comparable and even superior performance to traditional mixes. CSA cements, on the other hand, need reduced temperature processing and emit less carbon dioxide during manufacturing. Therefore, the adoption of these alternate binders holds great prospect of cutting carbon footprint of concrete manufacturing. Also, carbon capture technologies are increasingly being designed. These revolutionary solutions try to capture carbon dioxide (CO2) emissions from cement plants and use the captured CO2 in the manufacturing of artificial limestone. This technology could potentially turn cement in to a carbon-neutral and on occasion even carbon-negative material by sequestering CO2 into concrete.
