Abstract

This report provides a comprehensive account of the data and observations gained from the research work carried out at the Department of Civil Engineering, Glasgow University on this 4-month contract funded by Technip UK Ltd from December 1st, 2009 to March 31st, 2010. The principal objective of the project was to determine by experiment which, if any, of a group of chemical additives were effective in accelerating the regain of strength of a marine clay following gross disturbance/remoulding by injection of water (and consequent increase in water content). The results of the test programme suggest that dosing with Calcium Hydroxide yields very promising results, and these results are presented at length. Other results are reported in the appendices and only briefly discussed herein.<p></p> Towards the end of the contract, further testing of the effect of the Calcium Hydroxide additive was undertaken at lower water contents than originally specified. In addition, some long-term tests (up to one year), which fall outside the scope of the contract, are currently being undertaken to establish whether the observed strength gain is permanent.<p></p>
