Resumen
Civil construction has great representation in the consumption of natural
resources, involving industries that manufacture the materials needed to carry
out works, it is also responsible for a large portion of solid waste generation.
The inappropriate disposal of waste generated in the construction and
demolition is one of the factors that are discussed in conferences and meetings
in various regions of Brazil and the world. In the face of this situation arise
policies of construction and demolition waste management (RCD) aimed at
recycling and reducing the generation of this waste. Due to the heterogeneity of
this material it is necessary to characterize the recycled aggregates for the
study of possible applications. The objective of this work is to identify possible
applications for aggregates of RCD following the requirements of the standards.
Tests were carried out on two samples (RCD1 and RCD2), both of them
aggregates recycled by a plant installed in Rio Grande do Norte. The results
showed that the samples do not apply as aggregates to structural or nonstructural
concrete because they do not meet the requirement of abrasion wear,
presenting a result of more than 50% of worn material, but these aggregates
can be applied in paving works, against interior flooring of housing units, pipe
fastening and other commonly used applications. Applications in mortars need
to carry out specific tests for approval in the requirements required by standard.
