摘要：
Cold ramming paste was successfully synthesized used electro-calcined anthracite (ECA) and artificial graphite as aggregate and phenol-formaldehyde (PF) resin as binder. Synthesized paste was measured by electrical resistivity, compressive strength, Infrared Spectrum (IR) and Thermo Gravimetry (TG), etc. The results show that the synthesized paste has some excellent physical properties such as low electrical resistivity and high compressive strength, all of which can meet industry requirements. Thermal decomposition and condensation of the paste can be divided into four stages by TG. Finally, it is found that the synthesized cold ramming paste is an ecofriendly material by the toxicity measurement of gas phase escaping from the heated paste.
