In order to study the effects of rubber particles,sulphoaluminate cement(SAC)and ordinary portland cement(OPC)on the mechanical properties of the restorative materials,the fluidity,compressive strength,flexural strength,percentage of strength increase and flexural ratio of the restorative materials are ana-lyzed with the cement content and rubber content as variables.The results show that the initial fluidity and 20min fluidity of the new repair material are increased by adding OPC,while the initial fluidity and 20min fluidi-ty of the new repair material are decreased by adding rubber.With the increase of OPC and rubber content,the compressive strength and flexural strength of the new repair materials show a decreasing trend,but the toughness is improved.
