Abstract
The amount of construction and demolition waste has increased
considerably over the last few years. Crushing concrete to produce
coarse aggregate for the production of new concrete is one common
means for achieving a more environment-friendly concrete. This
experimental study demonstrates the mechanical properties of concrete
containing recycled concrete aggregate (RCA) subjected to different fire
durations. In the experimental work, the fresh concrete properties (slump < br />test) and the hardened concrete properties, (compressive strength,
splitting tensile strength, flexural strength and modulus of elasticity)
were carried out. A total of thirty concrete mixes with different cement
contents (300, 350, and 400 Kg/m3) at w/c ratio (0.5) were made and the
percentage of substitution of natural concrete coarse aggregate by the
recycled concrete coarse aggregate subjected to fire durations (1,2 and 3
hours) at fire temperature (600ºC) was (0%, 25%, 50% and 100%). In
the process of mixing, equal consistence among all concrete mixes was
achieved. The obtained results indicate that the recycled coarse
aggregate subjected to fire can successfully be used for making
structural concrete.
