Recycling Waste Latex Paint in Concrete
Project managed by the University of Western Ontario, in London,
Project
Management Ontario.
Objectives
To determine if WLP used as partial replacement for mixing water can
improve some key properties of concrete to create added value.
Project
Summary
WLP is used as partial replacement for mixing water in concrete and the
resulting properties of the concrete are studied. This project is intended
to identify and quantify the benefits of using WLP in concrete, to identify
the optimum applications of WLP in concrete, to demonstrate the
consistency of the result of using WLP and to measure the effect of using
WLP against recognized standards of testing concrete performance. The
results of this project are expected to show not only the benefits of using
WLP in concrete, but to give confidence to the concrete supply industry
regarding the effect of WLP in relation to recognized concrete
performance standards.
The project takes place over 2 years, 2005 and 2006.
Timeline
Resources
Project funded by Product Care Association, Materials and
Manufacturing Ontario, and the Natural Science and Engineering
Research Council of Canada.
Performance The project will measure:
Measures
 the early age properties of WLP concrete mixtures
 durability of hardened concrete incorporating WLP
 chemical resistance of WLP modified concrete
 outdoor exposure using experimental concrete blocks and slabs
against ASTM standards.
Correlation
to the
Dialogue
This is a market development project under “non-paint” uses. A positive
outcome could lead to a demand for WLP for concrete manufacture,
giving value to what is now a waste material. This could create a local
option for disposal of WLP not requiring subsequent processing, within a
reasonable distance of almost any geographic location.
