Service life prediction and fibre reinforced cementitious composites

En Ph.D.-afhandling på engelsk der behandler emnet
levetidsbestemmelse af fiberarmerede cementbaserede kompositmaterialer.
Fordele og ulemper beskrives. Afhandlingen har som formål at belyse anvendeligheden af en systematisk CIB/RILEM metode. Metoden er diskuteret generelt i SBI Report 221: "Service life prediction and cementitious composites".

The present Ph.D. thesis addresses the service life concept on the fibre reinforced cementitious composites. The advantages and problems of adding fibre to a cementitious matrix and the influence on service life are described. 

In SBI Report 221, Service life prediction and cementitious composites, the factors affecting the pure cementitious composite are described. Different sizes and types of fibre reinforced cementitious composites have been chosen to illustrate different ageing and deterioration mechanisms. Some ageing mechanisms can be accelerated and others cannot which is demonstrated in a test programme. Moisture, micro structural and mechanical properties were measured before, during and after ageing, with the purpose of giving a detailed "picture" of the materials during ageing.
