Paper Details

In this study recycled coarse aggregates obtained by crushed concrete were used for concrete production.Four different recycled aggregate concretes were produced; made with 0%, 25%, 50% and 100% of recycled coarseaggregates, respectively. The mix proportions of the four concretes were designed in order to achieve the samecompressive strengths. Recycled aggregates were used in wet condition, but not saturated, to control their fresh concreteproperties, effective w/c ratio and lower strength variability. The necessity to produce recycled aggregate concrete withlow–medium compressive strength was verified due to the requirement of the volume of cement. The influence of theorder of materials used in concrete production (made with recycled aggregates) with respect to improving its splittingtensile strength was analysed. The lower modulus of elasticity of recycled coarse aggregate concretes with respect toconventional concretes was measured verifying the numeral models proposed by several researchers.
