Abstract:
Microfibers have been shown to significantly improve the resistance to freezing and thawing and salt-scaling of cement pastes and mortars. This improvement has been attributed to the ability of the fibers to either stop or slow crack propagation. In this article, the durability of concrete containing pulp and paper industry by-products consisting of wood cellulose fibers and papermaking fillers is investigated. This by-product may be a source of microfibers that could be “greener” and more cost-effective than any other fibers available to the concrete industry.
