The advantages of reducing the transport of aggressive agents through the concrete cover, either through the use of cements with lower carbon footprint, incorporating supplementary cementitious materials (SCM) or using high performance concrete (HPC) to increase its density, are proven technologies to extend the service-life of concrete structures.
Use of coarse recycled concrete aggregates and vitrified MSW ash in eco-concrete design
Concrete industry is responsible for 8% of CO2 emissions (primarily related to cement production) and for about 20 billion tons of natural aggregate consumption.
