| Abstract: | The rejected polyester drinking bottle can be used to prepare low cost recovery unsaturated polyester after alcoholysis and condensation polymerization, which can be used to prepare earlier strengthened polymer modified cement mortar. Its earlier bending strength and earlier adhesion strength with common cement trial block are greatly higher than those of common cement mortar. This method also has the following advantages, such as make use of reject material, good to environment and lower cost. |
