ABSTRACT:
A method of manufacturing a lightweight building element comprises providing a lightweight aggregate of particles having diameters in the range of 2 mm to 20 mm, mixing the particles together to produce graduated particle size distribution of the mixture, adding a quicksetting binder to the mixture in a predetermined amount sufficiently small so that free spaces are produced between the particles after setting and drying, allowing the binder to set and dry to form a porous body of particles bound together by the binder and having free spaces between the particles, introducing expanding plastic into the free spaces, and expanding the plastic in situ to form a cellular plastic structure completely filling the free spaces.
