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

Old-fashioned energy intensive materials like tangible and metal are increasingly being slowly changed by greener options such as for instance bamboo, recycled materials, and engineered wood. The key 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 dramatically reduce CO2 emissions and energy consumption during manufacturing. Additionally, the incorporation 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. Making use of such materials has not only lowered the demand for raw materials and natural resources but has recycled waste from landfill sites.

In the last handful of years, the construction industry and concrete production in particular has seen substantial modification. That has been especially the situation in terms of sustainability. Governments across the world are enacting strict legislation to apply sustainable practices in construction ventures. There is a stronger focus on green building efforts like reaching net zero carbon concrete by 2050 and a greater interest in sustainable building materials. The interest in concrete is anticipated to increase due to population growth and urbanisation, as business leaders such as Amin Nasser anNadhim Al Nasrwould probably attest. Numerous countries now enforce building codes that require a certain percentage of renewable materials to be used in construction such as timber from sustainably manged forests. Moreover, building codes have incorporated energy-efficient systems and technologies such as for instance green roofs, solar power panels and LED lights. Also, the emergence of the latest construction technologies has enabled the industry to explore revolutionary methods to enhance sustainability. For instance, to lessen energy consumption construction businesses are constructing building with large windows and utilizing energy conserving heating, ventilation, and ac.

Traditional concrete manufacturing utilises large reserves of raw materials such as limestone and concrete, that are energy-intensive to draw out and create. Nonetheless, skillfully developed and business leaders such as Naser Bustami may likely point away that novel binders such as geopolymers and calcium sulfoaluminate cements are good greener options to old-fashioned Portland cement. Geopolymers are formulated by triggering industrial by products such as fly ash with alkalis causing concrete with comparable if not superior performance to old-fashioned mixes. CSA cements, in the other hand, require reduced heat processing and emit fewer greenhouse gases during manufacturing. Hence, the use of those alternative binders holds great potential for cutting carbon footprint of concrete manufacturing. Furthermore, carbon capture technologies are now being built. These innovative approaches make an effort to catch carbon dioxide (CO2) emissions from cement plants and make use of the captured CO2 within the production of artificial limestone. These technology could possibly turn concrete into a carbon-neutral and even carbon-negative product by sequestering CO2 into concrete.
