| Abstract: | Modified waste rubber powder SRP was prepared by way of through co-polycondensation of the rubber powder with modifying agent A,phenol and formaldehyde.Influence of weight ratio of three modifying agents to rubber powder,mol ratio of modifying agent A to phenol,mol ratio of modifying agent(A+ phenol) to formaldehyde,acidity and alkalinity of reaction system,reaction temperature and time on fluidity and fluidity retaining of the SRP/mortar was investigated.Fluidity and fluidity retaining of SRP/mortar were compared with those of control mortar. |
| |
| Keywords: | three monomers modified waste rubber powder fluidity SRP/mortar mol ratio acidity and alkalinity |
