A method for recycling concrete waste includes the steps of: a) heating the concrete waste to provide a measure of fragility to the concrete waste; b) milling and sieving the heated concrete waste to separate coarse aggregate from the concrete waste; and c) milling and sieving a remaining portion of the concrete waste remaining after separation of the coarse aggregate to separate the remaining portion of the concrete waste into a cement-containing fraction and fine aggregate.
