Performance of polymer modified concrete incorporating polyvinyl acetate waste

Generation of waste latex paint (WLP) from the manufacturing process of binder paint products is increasing globally due to the increasing need for aesthetical features in association with rapid industrialisation and urbanisation. The volume of waste generated in the form of solids and effluents fro...

description Generation of waste latex paint (WLP) from the manufacturing process of binder paint products is increasing globally due to the increasing need for aesthetical features in association with rapid industrialisation and urbanisation.
