Sustainability has become a key focus within the construction industry due to government pressures.

Within the last number of decades, the construction industry and concrete production in specific has seen substantial modification. That is especially the case when it comes to sustainability. Governments across the world are enacting strict legislation to apply sustainable methods in construction projects. There exists a more powerful focus on green building efforts like reaching net zero carbon concrete by 2050 and a higher interest in sustainable building materials. The interest in concrete is expected to increase as a result of populace growth and urbanisation, as business leaders such as Amin Nasser an Nadhim Al Nasr would likely attest. Numerous nations now enforce building codes that need a certain percentage of renewable materials to be utilized in construction such as timber from sustainably manged woodlands. Moreover, building codes have incorporated energy efficient systems and technologies such as for example green roofs, solar power 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 companies are constructing building with big windows and utilizing energy efficient heating, air flow, and ac.

Conventional concrete manufacturing uses large stocks of raw materials such as limestone and cement, which are energy-intensive to draw out and produce. But, industry experts and business leaders such as Naser Bustami would likely aim out that novel binders such as for example geopolymers and calcium sulfoaluminate cements are effective enviromentally friendly alternatives to traditional Portland cement. Geopolymers are produced by activating industrial by products such as fly ash with alkalis causing concrete with comparable as well as superior performance to traditional mixes. CSA cements, regarding the other hand, need lower heat processing and emit less greenhouse gases during manufacturing. Thus, the use of these alternate binders holds great potential for cutting carbon footprint of concrete manufacturing. Also, carbon capture technologies are now being built. These revolutionary methods make an effort to capture co2 (CO2) emissions from cement plants and use the captured CO2 into the production of artificial limestone. These technology may potentially turn cement into a carbon-neutral if not carbon-negative product by sequestering CO2 into concrete.

Conventional power intensive materials like concrete and metal are now being slowly replaced by greener options such as bamboo, recycled materials, and engineered wood. The main sustainability improvement into the construction industry however since the 1950s happens to be the inclusion of supplementary cementitious materials such as fly ash, slag and slicia fume. Replacing a percentage of the cement with SCMs can dramatically reduce CO2 emissions and energy consumption during manufacturing. Furthermore, the inclusion of other lasting materials like recycled aggregates and commercial by products like crushed class and rubber granules has gained increased traction within the previous couple of decades. The utilization of such materials have not only lowered the interest in raw materials and resources but has recycled waste from landfills.
