ASSESSMENT OF THE E-MODULUS OF RECYCLING CONCRETE WITH DIFFERENT REPLACEMENT RATE
Boekbijdrage - Boekhoofdstuk Conferentiebijdrage
Most aggregates used in concrete are from natural origin, obtained from quarries or dredged
from the river- or sea-bed. Natural aggregates are finite in quantity and their exploitation isn’t
without effect on fauna and flora. Therefore the demand for recycling aggregates has been
increasing for a couple of years. These recycled aggregates are being used in combination
with natural aggregates. Currently, the largest part of recycled aggregates are used in rather low
rated applications such as road-foundations and parking lots. Yet, the Flemish government
urges to use recycled concrete aggregates with a higher added value as in structural concrete.
In order to be able to do so, the properties and the behaviour of recycling concrete should be
well known. One of the most important properties to be known in relation to the dimensioning
of construction elements made of recycling concrete is undoubtingly the Elastic Modulus or
Modulus of Young.
This paper discusses the results of an investigation on the influence of the replacement
rate of natural aggregates by recycled concrete aggregates on the Modulus of Elasticity of
recycling concrete. The results were formulated in empirical formulas and were also
compared with results from previous investigations done by other researchers.
