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

Within the last number of years, the construction industry and concrete production in particular has seen important change. Which has been particularly the case regarding sustainability. Governments around the globe are enacting stringent legislations to apply sustainable methods in construction projects. There is a stronger 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 boost as a result of population development and urbanisation, as business leaders such as Amin Nasser an Nadhim Al Nasr would likely attest. Many nations now enforce building codes that want a certain percentage of renewable materials to be utilized in construction such as 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. Furthermore, the emergence of the latest 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 using energy efficient heating, air flow, and ac.

Conventional concrete manufacturing employs large 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 probably point down that novel binders such as geopolymers and calcium sulfoaluminate cements are excellent greener alternatives to conventional Portland cement. Geopolymers are manufactured by activating industrial by products such as fly ash with alkalis causing concrete with comparable if not superior performance to traditional mixes. CSA cements, regarding the other hand, need lower heat processing and emit less carbon dioxide during production. Therefore, the adoption of those alternate binders holds great possibility of cutting carbon footprint of concrete manufacturing. Also, carbon capture technologies are now being designed. These revolutionary solutions try to catch carbon dioxide (CO2) emissions from cement plants and use the captured CO2 into the production of artificial limestone. These technology may possibly turn concrete in to a carbon-neutral or even carbon-negative material by sequestering CO2 into concrete.

Old-fashioned energy intensive materials like concrete and metal are now being slowly changed by more environmentally friendly alternatives such as bamboo, recycled materials, and manufactured timber. The primary sustainability enhancement in the construction sector though since the 1950s was the inclusion of supplementary cementitious materials such as fly ash, slag and slicia fume. Substituting a portion of the concrete with SCMs can significantly reduce CO2 emissions and energy consumption during manufacturing. Additionally, the incorporation of other renewable 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 demand for raw materials and resources but has recycled waste from landfills.
