Concretes produced with recycled aggregates are the subject of several papers recently published in the technical literature. Substitution of natural aggregates can be one of possibilities to take care of landfills and increase of CO2 emissions into the atmosphere in Latvia. Recycled aggregate is a valuable resource; value-added consumption of recycled aggregate, as replacement for virgin aggregate in concrete, can yield significant energy and environmental benefits. In present study recycled aggregates from concrete specimens with known mix composition and Portland cement partial substitution have performed good mechanical strength results and higher permeability. The general application of fluorescent waste glass and bottom wood ash CAW and reduced cement volume can be solution for structural concrete element production in concern to reduce the amount of waste disposed and preserve natural resources, as also to reduce CO2 into the atmosphere.
