Lime composite reinforced with organic fibres
Drdácký, Miloš ; Michoinová, D.
Paper presents selected results of research into a complex influence of addition of natural fibres (horse and goat hair), natural fibrous particles (saw dust) and modern polypropylene fibres on some material characteristics of lime mortars. There are presented recommendations for use of such mortars in conservation practice.

Fibre reinforced mixtures for restoration and safeguaerding of monuments
Drdácký, Miloš ; Michoinová, D. ; Procházka, P.
Scientific recommendations for receipt and technology procedures of preparation of mixtures with required remedy characteristics, namely with a higher resistance against occurrence of macro cracks and propagation of micro cracks. Based on mathematical modelling of composite materials with inorganic (brittle) matrix and natural as well as man made polymeric fibres, an optimum cross section shape of the fibre has been determined. Characteristics of samples made from resulting mixtures have been experimentally tested from the point of view of mechanical behaviour including fracture characteristics and long term stability at cyclic changes of environment and climatic loading. The natural fibrous materials involved horse and goat hair, saw dust and husk, the man made polypropylene fibres.
