Lava lightweight concrete, developed by the company Burkhard Schuller Baustoffservice, is a mix of volcanic rock: e.g., of zeolite, pumice and lava. Volcanic rock can be used without additional energy input, since quarrying takes place gently and without blasting. This ancient material can be used as eco-friendly insulation in buildings, and its warm coloring and sound-insulating properties positively affect the wellbeing of occupants. Apart from its long service life, this mineral construction material can be reused following demolition of the building.
Instead of heavy aggregate, a very light, mineral aggregate with high thermal insulation is used in lava lightweight concrete. The binder matrix can be lightly foamed to increase the insulating effect further and to reduce the weight. Foaming has the effect that around 20 % of the concrete volume can consist of artificial air voids.
