Title: Long-term Strength and Serviceability of paving constructed with Pre-mix Recycled Aggregate Concrete
Appears on pages(s):
Abstract:This paper discusses laboratory and field serviceability evaluation of recycled premixed concrete (RC) and conventional concrete (NC) used in construction of recreational facilities. The trials involved production and construction with recycled concrete made with 100% replacement of virgin coarse aggregate with recycled concrete aggregate (RCA). Two recreational facilities were
investigated. The compressive strength of recycled concrete after 7years falls within 10% of the conventional concrete with the overall system serviceability remaining satisfactory for all facilities. Initial workability and placement of both RC and NC were found to be comparable. For standard cured specimens, higher drying shrinkage values, approx 25% are observed for RC with and without polypropylene fibres. However, corresponding in-situ NC and RC shrinkage measurements are comparable.
