OBTAINING HIGH STRENGTH POROUS AGGREGATES FOR CONCRETE

POLUCHENIE VYSOKOPROCHNYKH PORISTYKH ZAPOLNITELEJ DLYA BETONA

Following a brief explanation of the low strengths obtained for expanded clays, the authors describe a heating technique at 1450 or even 1500 deg C, with fusion of the raw clay, followed by rapid freezing causing re-crystallization. After pulverising, the addition of additives and humidification the material is granulated, then expanded between 1000 and 1100 deg C in a rotary furnace or a fluidified bed. The process is still experimental. (TRRL)
