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

In the last number of years, the construction industry and concrete production in particular has seen significant change. That has been particularly the case in terms of sustainability. Governments across the world are enacting strict rules to implement sustainable practices in construction projects. There exists a more powerful focus on green building efforts like reaching net zero carbon concrete by 2050 and an increased interest in sustainable building materials. The demand for concrete is expected to boost as a result of population growth and urbanisation, as business leaders such as Amin Nasser an Nadhim Al Nasr would likely attest. Numerous countries now enforce building codes that require a certain portion of renewable materials to be utilized in construction such as timber from sustainably manged woodlands. 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 the latest construction technologies has enabled the industry to explore innovative methods to enhance sustainability. For example, to cut back energy consumption construction businesses are constructing building with big windows and using energy saving heating, air flow, and air-con.

Traditional concrete manufacturing uses huge reserves of raw materials such as for example limestone and concrete, which are energy-intensive to extract and create. Nevertheless, industry experts and business leaders such as Naser Bustami may likely aim out that novel binders such as for example geopolymers and calcium sulfoaluminate cements are good enviromentally friendly options to traditional Portland cement. Geopolymers are formulated by activating industrial by products such as fly ash with alkalis causing concrete with comparable and on occasion even superior performance to mainstream mixes. CSA cements, regarding the other hand, need lower heat processing and emit less greenhouse gases during manufacturing. Thus, the adoption among these alternative binders holds great possibility cutting carbon footprint of concrete manufacturing. Also, carbon capture technologies are now being improved. These revolutionary methods make an effort to capture co2 (CO2) emissions from concrete plants and use the captured CO2 into the production of artificial limestone. This technology could potentially turn concrete as a carbon-neutral if not carbon-negative product by sequestering CO2 into concrete.

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 industry however since the 1950s was 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. Additionally, the incorporation of other lasting materials like recycled aggregates and industrial by products like crushed class and rubber granules has gained increased traction within the previous couple of decades. The application of such materials has not only lowered the interest in raw materials and resources but has recycled waste from landfills.
