Q2. Explain in simple terms why a secondary aggregate obtained from a manufactured source (such as GGBS or china clay waste) is likely to be less problematic to use in a concrete mix than a secondary aggregate that has been obtained from a recycled source?

Answer #1

The utillization of GGBS or clay waste as an aggregate of concrete mixture will improve the economic value of the concrete due to the brighter color and high aesthetic level of the products. Many construction and development activities today consume large amounts of concrete. The amount of construction waste is also increasing because of the demolition process. Much of this waste can be recycled to produce new products and increase the sustainability of construction projects.As recycled waste and concrete materials recycled in the natural aggregate in concrete because of their hard and strong physical properties. To ensure more better condition it is better to use the secondary aggregate from the manufactured sources. So it will be very easy for the manufactures for using the secondary aggregate obtained from manufactured source concrete mix than the secondary aggregate.
