The Environmental Impacts of Industrialization | EcoMENA

The Impact of Industrialization. There are four primary impact points when it comes to industrialization — air, water, soil and habitat. The biggest problem is air pollution, caused by the smoke and emissions generated by burning fossil fuels. The United State’s EPA regulates more than 80 different toxins that can be found in industrial

Cement and Concrete Sustainability - PCA

Long life- Concrete structures are long-lived, such as pavements that have an average service life of 30-50 years.; Low life-cycle cost - Concrete consumes minimum materials, energy and other resources for construction, and requires little to no maintenance throughout its service life.; Safety and reliability - Concrete does not rust, rot or burn. . Concrete pavements are less susceptible to

Environmental Impact of Polymer-Fiber Reinforced Concrete

The environmental impact and mechanical behaviour of fibre reinforced concrete (FRC) depends largely on the interactions between the fibres and the brittle concrete matrix: physical and chemical adhesion; friction; and mechanical anchorage induced by complex fibre geometry or by deformations or other treatments on the fibre surface. Surface treatments of the synthetic (mostly polypropylene

Life cycle assessment and embodied carbon

Environmental impacts in one category can be caused by many different emissions and therefore characterisation factors are used to combine the impact of different substances. A good example of this, which is also relevant to embodied carbon assessments, is the impact category of global warming potential (GWP).

Portland cement and the environment - Concrete

Portland cement and the environment. Portland cement is manufactured by heating limestone or chalk with clay in a rotary kiln to a high temperature (about 1450°C) to produce hard nodules of clinker that are then ground with a little gypsum in a ball mill. The firing process consumes significant quantities of fuel, usually coal or petroleum coke.

How can we reduce concrete's hefty carbon footprint? | Ensia

The Canadian company CarbonCure Technologies has developed a process that injects waste CO 2 into a typical concrete production process, effectively replacing a small amount of cement with CO 2 without compromising the concrete's strength or integrity. Once in the mix, the CO 2 changes into calcium carbonate, the chemical equivalent of the limestone used in the production of conventional cement.
