Chapter 7. Conclusions and Recommendations for Future Work

Previous | Table of Contents | Next


This report has reviewed the basics of ASR, summarized past research and field applications of lithium compounds in concrete construction, and presented revised recommendations for using lithium in new concrete and as a post-treatment for existing structures. Some of the main findings and conclusions from this report are:


As the availability of high-quality, low-reactivity aggregates continues to dwindle, the use of alternative means of controlling ASR certainly will become even more important. Given the past successes of using lithium compounds to inhibit expansion, both in the laboratory and in the field, the future of using lithium in concrete construction appears bright. However, there are several technical and practical issues that deserve further investigation:
