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

Old-fashioned energy intensive materials like tangible and metal are increasingly being gradually changed by more environmentally friendly alternatives such as bamboo, recycled materials, and engineered wood. The key sustainability improvement in the building sector however since the 1950s has been the inclusion of supplementary cementitious materials such as fly ash, slag and slicia fume. Replacing a percentage of the concrete with SCMs can significantly 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 rubber granules has gained increased traction into the previous few decades. The employment of such materials has not only lowered the demand for raw materials and resources but has recycled waste from landfills.

Within the last couple of decades, the construction sector and concrete production in specific has seen significant change. That has been particularly the case in terms of sustainability. Governments around the globe are enacting strict legislation to apply sustainable methods in construction ventures. There exists a more powerful focus on green building efforts like reaching net zero carbon concrete by 2050 and a greater demand for sustainable building materials. The demand for concrete is expected to improve because of population growth and urbanisation, as business leaders such as Amin Nasser an Nadhim Al Nasr would likely attest. Many countries now enforce building codes that require a certain percentage of renewable materials to be used in building such as timber from sustainably manged forests. Moreover, building codes have incorporated energy-efficient systems and technologies such as for instance green roofs, solar power panels and LED lighting. Additionally, the emergence of new construction technologies has enabled the industry to explore revolutionary methods to enhance sustainability. For instance, to lessen energy consumption construction companies are building building with large windows and utilizing energy-efficient heating, air flow, and air-con.

Conventional concrete manufacturing uses large stocks of raw materials such as for example limestone and cement, which are energy-intensive to extract and create. However, industry experts and business leaders such as Naser Bustami would probably aim down that novel binders such as geopolymers and calcium sulfoaluminate cements are good 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 conventional mixes. CSA cements, regarding the other side, require reduced heat processing and emit fewer carbon dioxide during production. Thus, the use of those alternative binders holds great possibility cutting carbon footprint of concrete manufacturing. Also, carbon capture technologies are increasingly being developed. These revolutionary methods aim to catch co2 (CO2) emissions from cement plants and make use of the captured CO2 within the manufacturing of artificial limestone. This technologies could possibly turn concrete into a carbon-neutral and sometimes even carbon-negative material by sequestering CO2 into concrete.
