The conclusion is that currently in Chile although the existence of recycled aggregate use is known this is not the case on a technical level for professionals in the sector

Recycled aggregate concrete RAC is an alternative to using natural aggregate NA in concrete Recycled concrete aggregate RCA are aggregates obtained by recycling clean concrete waste where content of other building waste must be very low – below few per cent

Recycled aggregate was made by crushing the waste concrete of laboratory test cubes and precast concrete columns Three types of concrete mixtures were tested concrete made entirely with natural aggregate NAC as a control

Introduction Recycled aggregate is produced by crushing concrete and sometimes asphalt to reclaim the aggregate Recycled aggregate can be used for many purposes The primary market is road base For information on recycling asphalt pavement into new asphalt pavement See Asphalt Pavement Recycling

The utilization of recycled aggregate is particularly very promising as 75 per cent of concrete is made of aggregates In that case the aggregates considered are slag power plant wastes recycled concrete mining and quarrying wastes waste glass incinerator residue red mud burnt clay sawdust combustor ash and foundry sand

To obtain good quality concrete using recycled aggregate it is necessary to follow the minimum requirements defined by the respective Building Standards Acceptable properties of aggregates are an elemental base for concrete quality however adequate

These can be either primary aggregates extracted from the ground in quarries or secondary aggregates recycled from construction waste Aggregates are an essential material in building and repairing things such as roads railways and homes The following pages provide an introduction to aggregates alongside a geological summary of the primary aggregate sources across Herefordshire and Worcestershire Different organisations may define aggregates
