Zastosowanie betonów lekkich do konstrukcji budowlanych, w szczególności do sprężonych płyt stropowych

Today's race for innovation and new solutions require from engineers to create new design solutions. One of these innovate solutions could be the using of lightweight concrete for structures subjected to high loads. Lightweight concrete despite smaller and above all worse aggregates have very good mechanical properties. Much less dead weight could lead to significant savings in the amount of reinforcement or massiveness of supports and foundations. The work has shown the possibility of using lightweight concrete for prestressed structures, based on a review of studies of lightweight concrete and numerical calculations.
