Abstract


Although there are many research studies about plaster strengthened with glass fibre E in Spain, there are no publications which advise the users (plasterers, manufacturers of prefabricated blocks or suspended ceilings, etc) about the most appropriated types of fibre E in respect to its dispersebility degree in the matrix, its lengths, the percentage, or even the type of strengthening, etc. The study of the use of this strengthener is to achieve an improvement in the mechanical behaviour of plaster as well as better conditions in the paste workability.
The company Vetrotex, with the technical personnel and together with the Department of Architectural Constructions and their control (E. U. A. T. M.) have started a serious research on plaster strengthened with E fibre.
Conclusions shown in this first article are about the influence of the dispersebility degree of glass fibres in the mechanical behaviour of the compound as well as its workability.
The degree of dispersibility of the fibres in the matrix is closely related to the type of covering used in the production of the strengthening fibres.
