A Study on the Durability of Epoxy-Modified Mortars and Concretes without Hardener |
| Abstract |
The purpose of this study is to evaluate the durability of epoxy-modified mortars and concretes have been widely used as finish and repair materials in the construction industry. In the production of conventional epoxy-modified mortars and concretes, the use of any hardener is indispensable. However, there is the fact that even without any hardener, the hardening process of epoxy resin can proceed by the action of hydroxides in cement mortars and concretes. The epoxy-modified mortars and concretes are prepared with various polymer-cement ratios and teted for Cl ion penetration, carbonation, chemical resistance and abrasion. As a result, the epoxy-modified mortars and concretes without the hardener have an excellent durability compared with those of with the hardener at low polymer-cement of 10% or less. |
