Abstract
The invention discloses a method for preparing cement mortar from waste rubber and bone meal. According to the method, the waste rubber is subjected to grafting modification by adopting dicumyl peroxide, so that the sclerotium toughness and the ductility of the cement mortar can be improved; therefore, the breaking strength of the mortar can be enhanced. By the full use of the commixing of waste rubber resources, the bone meal, hydroxyethyl cellulose and dispersion emulsion, the dispersivity of the cement mortar is improved.
Description
Technical field
