The journal Construction and Building Materials has published findings of a German Universität der Bundeswehr München investigation into the recycling of infra-lightweight concrete (ILC) into aggregates (or RLCAs) to produce a new building material called recycled ILC (RILC) that has properties comparable to the original material.
Researchers manually and mechanically processed large ILC elements, categorizing the resulting RLCAs by particle size before conducting compressive strength tests after a curing period of 28 days.
By this method, they found that RILC made from RLCAs demonstrated similar strength, elasticity, and thermal conductivity as the original ILC, despite a 31.6% increase in dry density. Perhaps more importantly, the RLCAs showed a “significant” CO₂ absorption potential equaling about 30% of the greenhouse gas emissions of the original ILC.
