best practice guide for the use of recycled aggregates in new concrete

Tests show promise for recycled aggregate use in New life for concrete BRANZ Build

However recycled aggregates have some different properties that need to be accounted for when producing recycled aggregates concrete The objective of this experiment was to study the possibility of using recycled aggregates produced from high quality concrete rejects in concrete structures designed according to common engineering practice and using current calculation procedurThe use of concrete aggregates and waste aggregates is likely to increase in ready mix concrete The best practice guide is a resource for concrete specifications and New Zealand standards for concrete aggregate supply NZS and concrete supply NZS
