- Abstract:
- This paper is intended to analyze the influence of dosages of asphalt emulsion on the mechanicalperformance of cement mortar.Different mass percentages of asphalt emulsion and cement (AE/C) were ap-plied to make asphalt emulsion cement mortar. The compressive strength and flexural strength of asphalt emul-sion cement mortar were tested. Finally,mechanism of asphalt emulsion on mechanical performance of cementmortar was analyzed by scanning the microscopic structures using scanning electron microscope ( SEM). Theresults show that when the content of asphalt emulsion is more than 5 %,compressive strength of the mortardecreases significantly while the flexural strength increases. When AE/C comprises 10% , the mortar showsthe greatest toughness. Asphalt emulsion dosage is a main factor that affects the mechanical performance of ce-ment mortar. When the thickness of asphalt film is larger than the length of hydrated calcium silicate ( C -s -H),cement hydration products neither grow through the asphalt membrane nor form a continuous networkstructure，which leads to lower toughness of the cement mortar.
