METHOD OF HEAT TREATMENT OF POLYSTYRENE CONCRETE PRODUCTS AND STRUCTURES Russian patent published in 1999 - IPC

Abstract RU 2136635 C1

FIELD: building industry. SUBSTANCE: method is carried out by direct electroheating of mixture at voltage of 36-42 V and maximum temperature rise of 18- 25 deg/h at isothermal temperature using modifiers to decrease electrical resistance to form uniform temperature field. Method makes it possible to reduce specific energy consumption by 15-20% and improve strength characteristics of final products by 17-30% by making temperature field more homogeneous within concrete body during heat treatment procedure. EFFECT: more efficient heat treatment method. 2 cl, 1 dwg, 2 tbl
