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

Over the past number of decades, the construction sector and concrete production in particular has seen important modification. Which has been particularly the case in terms of sustainability. Governments across the world are enacting strict rules to apply sustainable techniques in construction ventures. There exists a stronger attention on green building efforts like reaching net zero carbon concrete by 2050 and an increased demand for sustainable building materials. The interest in concrete is anticipated to improve because of populace growth and urbanisation, as business leaders such as Amin Nasser an Nadhim Al Nasr would probably attest. Many nations now enforce building codes that need a certain percentage of renewable materials to be utilized in building such as for instance timber from sustainably manged forests. Moreover, building codes have included energy efficient systems and technologies such as for instance green roofs, solar panel systems and LED lights. Additionally, the emergence of the latest construction technologies has enabled the industry to explore innovative solutions to enhance sustainability. As an example, to reduce energy consumption construction companies are building building with big windows and utilizing energy-efficient heating, air flow, and air-con.

Traditional energy intensive materials like concrete and steel are increasingly being slowly changed by greener alternatives such as for instance bamboo, recycled materials, and manufactured timber. The primary sustainability enhancement into the construction industry though since the 1950s was the introduction 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 production. Also, the incorporating of other lasting materials like recycled aggregates and industrial by products like crushed class and rubber granules has gained increased traction in the past couple of years. The usage of such materials has not only lowered the demand for raw materials and natural resources but has recycled waste from landfill sites.

Conventional concrete manufacturing employs large reserves of raw materials such as limestone and cement, which are energy-intensive to extract and create. But, skillfully developed and business leaders such as Naser Bustami would likely point out that novel binders such as geopolymers and calcium sulfoaluminate cements are good greener alternatives to conventional Portland cement. Geopolymers are produced by triggering industrial by products such as fly ash with alkalis causing concrete with comparable as well as superior performance to old-fashioned mixes. CSA cements, regarding the other side, need reduced heat processing and give off less carbon dioxide during manufacturing. Therefore, the use of those alternative binders holds great possibility of cutting carbon footprint of concrete manufacturing. Also, carbon capture technologies are increasingly being improved. These innovative methods try to capture carbon dioxide (CO2) emissions from concrete plants and make use of the captured CO2 into the manufacturing of artificial limestone. This technologies may possibly turn cement right into a carbon-neutral if not carbon-negative material by sequestering CO2 into concrete.
