As populations continue steadily to grow and towns expand, the interest in concrete increase.

Over the past handful of decades, the construction sector and concrete production in particular has seen significant modification. That has been particularly the case in terms of sustainability. Governments around the world are enacting strict rules to implement sustainable methods in construction projects. There is a stronger focus on green building attempts like reaching net zero carbon concrete by 2050 and a greater interest in sustainable building materials. The demand for concrete is anticipated to improve as a result of population development and urbanisation, as business leaders such as Amin Nasser anNadhim Al Nasrwould likely attest. Numerous nations now enforce building codes that need a certain portion of renewable materials to be used in construction such as for example timber from sustainably manged forests. Moreover, building codes have actually incorporated energy saving systems and technologies such as for instance green roofs, solar panel systems and LED lighting. Also, the emergence of new construction technologies has enabled the industry to explore innovative methods to enhance sustainability. For example, to lessen energy consumption construction businesses are constructing building with big windows and making use of energy-efficient heating, air flow, and air-con.

Traditional energy intensive materials like tangible and metal are now being gradually replaced by more environmentally friendly options such as bamboo, recycled materials, and manufactured wood. The main sustainability improvement within the building industry though since the 1950s happens to be the inclusion of supplementary cementitious materials such as fly ash, slag and slicia fume. Substituting a percentage of the concrete with SCMs can significantly reduce CO2 emissions and energy consumption during production. Also, the incorporating of other sustainable 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 use 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, industry experts and business leaders such as Naser Bustami may likely aim out that novel binders such as geopolymers and calcium sulfoaluminate cements are good greener alternatives to conventional Portland cement. Geopolymers are formulated by triggering industrial by products such as fly ash with alkalis resulting in 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. Hence, the use among these alternate binders holds great possibility cutting carbon footprint of concrete manufacturing. Furthermore, carbon capture technologies are now being developed. These revolutionary solutions aim to capture carbon dioxide (CO2) emissions from cement plants and use the captured CO2 into the manufacturing of artificial limestone. These technology could potentially turn concrete into a carbon-neutral as well as carbon-negative material by sequestering CO2 into concrete.
