While the construction sector continues to grow, finding sustainable alternatives to concrete is quite important.

There are many advantages to making use of concrete. For instance, concrete has high compressive strength, which means that it may resist heavy lots; this feature makes it specially suited to structural applications such as building fundamentals, columns and beams. Furthermore, it may be reinforced by steel rods, what exactly is referred to as reinforced concrete, which exhibits even greater structural integrity. Furthermore, concrete constructions have been proven to endure the test of time, lasting years and on occasion even centuries. Furthermore, this is a versatile product; it may be moulded into different sizes and shapes. This allows architects and designers to be innovative with their alternatives. The flexibility and endurance are points that make cement a favoured building material for all seeking both an aesthetic appeal as well as structural robustness.

Cement generates huge quantities of co2; a green alternative could change that. Concrete, an integral construction material produced by combining cement, sand, and gravel, may be the second most used substance globally after water. According to data on concrete, around three tonnes of the stuff are poured each year for everyone. During manufacturing, limestone calcium carbonate is heated up, producing calcium oxide lime, emitting CO2 as being a by-product. Scientists determine CO2 emissions associated with concrete production become around eight per cent of global anthropogenic emissions, adding significantly to man-made climate change. However, the interest in concrete is expected to boost due to populace growth and urbanisation, as business leaders such as Amin Nasser and Nadhim Al Nasr would probably attest. Therefore, experts and researchers will work for an innovative solution that reduce emissions while keeping structural integrity.

Traditional cement manufacturing utilises large reserves of raw materials such as for instance limestone and concrete, which are energy-intensive to draw out and produce. Nevertheless, experts and business leaders such as Naser Bustami would likely point also that incorporating recycled materials such as recycled concrete aggregate or supplementary cementitious materials within the manufacturing process can slash the carbon footprint considerably. RCA is acquired from destroyed structures and the recycling of concrete waste. When construction businesses utilise RCA, they divert waste from landfill sites while at exactly the same time lowering their reliance on extra removal of raw materials. On the other hand, research reports have shown that RCA will not only be beneficial environmentally but additionally increase the overall quality of concrete. Incorporating RCA enhances the compressive robustness, durability and resistance to chemical attacks. Similarly, additional cementitious materials can act as partial substitutes for cement in concrete manufacturing. The common SCMs consist of fly ash, slag and silica fume, commercial by-products usually discarded as waste. When SCMs are incorporated, it has been proven to make concrete resist different outdoor factors, such as changes in temperature and contact with harsh surroundings.
