Evaluation of Chloride Ion Attack in Self-Compacting Concrete Using Recycled Construction and Demolition Waste Aggregates

Buildings
Construction and demolition waste (CDW) destined for recycling companies has great potential for use in civil construction, since it gives rise to recycled aggregates of different particle sizes that can be used in concrete.

Porous Pavers: Effects of the Recycled Aggregate Size on Drainage Properties

MATEC Web of Conferences, 2014
Pervious pavers allow water to percolate through the pavement surface. One of its functions is to reduce runoff. This research studies the possible usage of recycled aggregates as the main base material for pervious pavers.

Impact of the Content Variation of the Different Recycled Wastes to the Properties of Concrete Paving Block

MATEC Web of Conferences, 2018
Recycled concrete aggregates have been widely studied and used in concrete products nowadays. However, other recycled wastes, such as glass, have not been involved too much in recycled aggregate concrete studies.
