A composition of exo-thermal cement terrazzo having electro-conductivity and the producing method thereof

摘要

PURPOSE: An electric conductivity heat generation cement terrazzo composition is provided to ensure electric conductivity, heat generation temperature control, stability and durability. CONSTITUTION: An electric conductivity heat generation cement terrazzo composition contains 18-25 weight% of cement, 3-10 weight% of graphite-containing material with 0.15-5mm of particle size; 5-30 weight% of additive containing silica fume or fly ash; 65-70 weight% of dolomite or calcite; and 5-10 weight% of alkali silicate having 2.0-3.0 mole ratio of lithium oxide and silicon dioxide.
