DURABILITY AND ENVIRONMENTAL IMPACT OF CEMENT MORTAR LININGS
Report No FR0473

Nov 1994

SUMMARY

I BENEFITS

The results of this work provide a detailed understanding for the users and applicators of cement mortar linings for corrosion protection of iron water mains. It supplies information that can aid rehabilitation planning decisions and assist users in meeting regulatory requirements. The tests developed for assessing performance of cement mortar linings, provide a basis for a type test, forming part of an appropriate standard or specification.

II OBJECTIVES

The objective of this programme of work is to provide guidance on the use of cement mortar linings in relation to their durability, effect on water quality and disposal of associated effluents.

III CONCLUSIONS

Laboratory test rigs provide the basis for reliable testing of the effects of cement mortar linings on water quality.

IV RECOMMENDATIONS

The detailed recommendations at the end of each section of this report for use of cement linings and disposal of the associated effluent should be adopted by users and contractors.

V RESUME

Findings of the first two years of the project are summarised and the work of the final year is detailed. Guidelines and research findings are provided in the areas of:
