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

Within the last handful of decades, the construction industry and concrete production in particular has seen significant change. That has been particularly the case when it comes to sustainability. Governments across the world are enacting strict regulations to implement sustainable practices in construction ventures. There exists a stronger focus on green building attempts like reaching net zero carbon concrete by 2050 and a greater demand for sustainable building materials. The demand for concrete is expected to boost because of population development and urbanisation, as business leaders such as Amin Nasser anNadhim Al Nasrwould probably attest. Many countries now enforce building codes that want a certain percentage of renewable materials to be used in building such as for instance timber from sustainably manged forests. Additionally, building codes have incorporated energy saving systems and technologies such as for instance green roofs, solar panels and LED lights. Also, the emergence of the latest construction technologies has enabled the industry to explore revolutionary solutions to enhance sustainability. For instance, to cut back energy consumption construction businesses are constructing building with big windows and using energy saving heating, air flow, and air conditioning.

Conventional concrete manufacturing utilises huge reserves of raw materials such as limestone and concrete, which are energy-intensive to draw out and produce. But, 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 conventional Portland cement. Geopolymers are designed by triggering industrial by products such as fly ash with alkalis resulting in concrete with comparable or even superior performance to old-fashioned mixes. CSA cements, on the other side, require reduced temperature processing and emit less greenhouse gases during manufacturing. Therefore, the use of these alternate binders holds great potential for 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 synthetic limestone. These technology could possibly turn concrete right into a carbon-neutral and sometimes even carbon-negative material by sequestering CO2 into concrete.

Conventional power intensive materials like concrete and metal are now being gradually replaced by more environmentally friendly alternatives such as bamboo, recycled materials, and manufactured wood. The main sustainability enhancement 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 incorporating of other lasting materials like recycled aggregates and industrial by products like crushed class and rubber granules has gained increased traction within the previous few decades. The utilization of such materials have not only lowered the demand for raw materials and resources but has recycled waste from landfills.
