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

In the last couple of decades, the construction sector and concrete production in particular has seen significant change. Which has been particularly the situation regarding sustainability. Governments around the globe are enacting stringent legislations to apply sustainable methods in construction projects. There is a more powerful attention on green building attempts like reaching net zero carbon concrete by 2050 and a higher demand for sustainable building materials. The interest in concrete is anticipated to increase due to populace development and urbanisation, as business leaders such as Amin Nasser anNadhim Al Nasrmay likely attest. Many nations now enforce building codes that need a certain percentage of renewable materials to be utilized in construction such as timber from sustainably manged woodlands. Additionally, building codes have incorporated energy saving systems and technologies such as for instance green roofs, solar power panels and LED lighting. Additionally, the emergence of the latest construction technologies has enabled the industry to explore revolutionary solutions to improve sustainability. For example, to cut back energy consumption construction businesses are constructing building with large windows and making use of energy saving heating, air flow, and air-con.

Conventional concrete manufacturing uses large stocks of raw materials such as for instance limestone and cement, which are energy-intensive to draw out and produce. However, skillfully developed and business leaders such as Naser Bustami would probably point away that novel binders such as for instance geopolymers and calcium sulfoaluminate cements are good enviromentally friendly options to traditional Portland cement. Geopolymers are designed by triggering industrial by products such as fly ash with alkalis causing concrete with comparable as well as superior performance to traditional mixes. CSA cements, regarding the other side, require reduced temperature processing and give off fewer greenhouse gases during manufacturing. Thus, the use of those alternative binders holds great possibility cutting carbon footprint of concrete manufacturing. Also, carbon capture technologies are now being engineered. These innovative solutions try to capture co2 (CO2) emissions from cement plants and make use of the captured CO2 in the manufacturing of synthetic limestone. These technology may potentially turn cement into a carbon-neutral and sometimes even carbon-negative material by sequestering CO2 into concrete.

Traditional power intensive materials like concrete and metal are now being gradually changed by greener options such as bamboo, recycled materials, and manufactured timber. The primary sustainability improvement within the construction industry however since the 1950s is the introduction of supplementary cementitious materials such as fly ash, slag and slicia fume. Substituting a percentage of the cement with SCMs can notably reduce CO2 emissions and energy consumption during manufacturing. Moreover, the incorporating of other renewable materials like recycled aggregates and industrial by products like crushed class and plastic granules has gained increased traction in the past couple of decades. The employment of such materials has not only lowered the interest in raw materials and natural resources but has recycled waste from landfills.
