FIELD: construction.
SUBSTANCE: invention relates to production of construction materials and specifically to production of expanded-clay concrete on activated ceramsite gravel. Method for preparation of expanded-clay concrete involves soaking granules claydite gravel in aqueous saturated solution of calcium hydroxide Ca(OH)2, putting some applications of granules claydite gravel on screen for draining solution until state of drop, treatment applications of granules jets of compressed carbon dioxide CO2 alternating with treatment of jets of water vapour to produce on their outer surfaces of active shells from calcium hydroxide Ca(OH)2 and calcium carbonate CaCO3, mixing cement, activated granules claydite gravel, construction sand and water saturated solution of calcium hydroxide Ca(OH)2, vibro forming of ceramsite-concrete mix in molds, inner surfaces of which is saturated with aqueous solution of calcium hydroxide are Ca(OH)2.
EFFECT: technical result is production of more uniform strength of expanded-clay concrete.
