As populations continue to increase and urban areas expand, the interest in concrete increase.

In the last handful of decades, the construction industry and concrete production in specific has seen substantial modification. Which has been particularly the situation with regards to sustainability. Governments around the globe are enacting strict rules to implement sustainable practices in construction projects. There exists a more powerful attention on green building efforts like reaching net zero carbon concrete by 2050 and a higher demand for sustainable building materials. The interest in concrete is anticipated to improve due to populace development and urbanisation, as business leaders such as Amin Nasser an Nadhim Al Nasr may likely attest. Many countries now enforce building codes that want a certain portion of renewable materials to be used in construction such as for example timber from sustainably manged woodlands. Moreover, building codes have included energy-efficient systems and technologies such as for instance green roofs, solar panels and LED lights. Also, the emergence of new construction technologies has enabled the industry to explore innovative methods to improve sustainability. For example, to cut back energy consumption construction companies are constructing building with big windows and utilizing energy-efficient heating, ventilation, and air-con.

Traditional concrete manufacturing utilises huge stocks of raw materials such as for instance limestone and cement, that are energy-intensive to extract and create. Nonetheless, industry experts and business leaders such as Naser Bustami would likely aim down that novel binders such as for example geopolymers and calcium sulfoaluminate cements are good enviromentally friendly alternatives to old-fashioned Portland cement. Geopolymers are produced 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, on the other side, need lower heat processing and emit less greenhouse gases during manufacturing. Thus, the use of these alternate binders holds great possibility of cutting carbon footprint of concrete manufacturing. Furthermore, carbon capture technologies are increasingly being introduced. These innovative solutions aim to catch carbon dioxide (CO2) emissions from cement plants and make use of the captured CO2 within the production of synthetic limestone. These technology may possibly turn concrete in to a carbon-neutral as well as carbon-negative product by sequestering CO2 into concrete.

Traditional power intensive materials like tangible and metal are now being gradually replaced by more environmentally friendly alternatives such as bamboo, recycled materials, and manufactured timber. The key sustainability improvement into the construction sector though since the 1950s happens to be the inclusion of supplementary cementitious materials such as fly ash, slag and slicia fume. Replacing a portion of the concrete with SCMs can significantly reduce CO2 emissions and energy consumption during manufacturing. Furthermore, the incorporating of other sustainable materials like recycled aggregates and commercial by products like crushed class and rubber granules has gained increased traction within the past couple of decades. The employment of such materials has not only lowered the interest in raw materials and natural resources but has recycled waste from landfills.
