Abstract
The paper presents a review of the research conducted by the author on the repair and rehabilitation of damaged tubular joints of offshore platforms using Ferrocement jackets and a specially developed high-performance grout (HPG). The repaired joint was tested under axial brace compression loading and found to be of its original strength. This research was the application of Ferrocement for curvilinear structures for repair. The author wanted to make use of the material for the construction of structures in straight and flat form. With this objective in mind experimental investigation was conducted on the hollow cored Ferrocement floor panel of size 900 mm 600 mm. This unit was precast with cement mortar 1:2 and cured for 7 days by immersion in a pond of water because only cement mortar is used in its production. Then it was arranged in a loading frame and tested under gradually increasing static loading till failure. The ultimate load sustained by the panel was 85 kN. With a factor of safety of 2, the intensity of the design load works out to 78.7 kNm2. The value recommended by the relevant guidelines is 2 kNm2. By this consideration, the hollow cored slab is safer for the people to live in. The paper presents the details of the experimental programme and the conclusions drawn therefrom.
