FIELD: chemistry.
SUBSTANCE: invention relates to production of artificial coarse porous aggregates. The method of making claydite gravel involves preparing a ceramic mixture, moulding gravel, applying a 0.3-0.7 mm thick layer of volcanic ash onto the surface of moulded gravel, drying the gravel to moisture content of not more than 7%, firing and cooling.
EFFECT: high strength of adhesion of the aggregate with hardened cement paste.
