From reinforcement to retardation: The dual role of plant-based fibres in lime-based plasters

Original language description

Lime plasters have relatively low strength, and it is appropriate to look for a suitable admixture to extend their strength and consequently also their durability. Natural fibres appear to be promising materials to meet all the ecological, economic and availability requirements. This paper investigates the performance of two representatives of natural fibres of plant origin (wood and rapeseed) in combination with lime-based plasters. It was proven, that attention should be paid especially to the kind of plaster to which these fibres were added. The same fibres exhibited distinct interactions with pure lime, hydraulic lime, and especially with pozzolana-lime-based plasters. In the case of the first two mentioned matrices, wood and rapeseed fibres caused an improvement in mechanical strength, while in the case of pozzolana lime, significant retardation and deterioration of the pozzolanic reaction was observed. It has been shown that these natural fibres decompose in an alkaline environment of slaked lime, leach saccharides and simultaneously bind calcium ions. As a result, they reduce the degree of pozzolanic reaction by half. To better understand this incompatibility, the effect of the fibres on the plaster structure was investigated in more detail by porosimetry, scanning electron microscopy and phase composition analysis. Based on these analyses, the natural fibres with plant origin were found to be incompatible with pozzolana lime-based plasters.
