Concrete production is major factor to CO2 emissions, but there was a desire for greener alternatives.

Within the last handful of decades, the construction industry and concrete production in particular 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 an increased 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 probably attest. Many countries now enforce building codes that want a certain portion of renewable materials to be used in building such as for instance timber from sustainably manged forests. Additionally, building codes have actually incorporated energy efficient systems and technologies such as for example green roofs, solar power panels and LED lighting. Furthermore, the emergence of new construction technologies has enabled the industry to explore innovative methods to improve sustainability. As an example, to lessen energy consumption construction companies are building building with large windows and using energy saving heating, ventilation, and air conditioning.

Conventional concrete manufacturing utilises huge reserves of raw materials such as for example limestone and cement, which are energy-intensive to draw out and produce. Nonetheless, industry experts and business leaders such as Naser Bustami would probably point down that novel binders such as for instance geopolymers and calcium sulfoaluminate cements are good enviromentally friendly alternatives to old-fashioned Portland cement. Geopolymers are manufactured by activating industrial by products such as fly ash with alkalis causing concrete with comparable and even superior performance to main-stream mixes. CSA cements, in the other side, require reduced temperature processing and give off fewer carbon dioxide during manufacturing. Therefore, the use of these alternate binders holds great potential for cutting carbon footprint of concrete manufacturing. Furthermore, carbon capture technologies are increasingly being engineered. These innovative techniques aim to capture co2 (CO2) emissions from cement plants and make use of the captured CO2 into the production of artificial limestone. This technology may potentially turn concrete as a carbon-neutral as well as carbon-negative product by sequestering CO2 into concrete.

Traditional energy intensive materials like tangible and steel are increasingly being slowly replaced by greener options such as bamboo, recycled materials, and manufactured timber. The primary sustainability enhancement within the building industry however since the 1950s is the introduction of supplementary cementitious materials such as fly ash, slag and slicia fume. Substituting a percentage of the concrete with SCMs can dramatically reduce CO2 emissions and energy consumption during manufacturing. Moreover, 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 previous few years. The use of such materials has not only lowered the interest in raw materials and resources but has recycled waste from landfills.
