<p>PCT No. PCT/GB92/02345 Sec. 371 Date Sep. 8, 1994 Sec. 102(e) Date Sep. 8, 1994 PCT Filed Dec. 17, 1992 PCT Pub. No. WO93/12052 PCT Pub. Date Jun. 24, 1993This invention relates to a method of inhibiting alkali-silica or alkali-aggregate reactions (AAR/ASR) in concrete structures by introducing lithium compounds or the like in conjunction with conventional techniques for the treatment of steel reinforcement corrosion. It is also proposed to provide lithium compounds in repair concretes, grouts or mortars and use the difference in concentration between the article under repair and the repair material to introduce the lithium ions into the concrete under repair, once again inhibiting AAR/ASR reactions.</p> |
