Abstract EN
The objectives of the present work were to evaluate the chemical compatibility between coir (Cocos nucifera L.) and cement and to study treatment methods to improve this compatibility.
In the inhibition test, cement hydration temperature evolution was measured in the absence and presence of untreated and treated coir fibres (cold water, hot water and NaOH), besides the addition of 4% of CaCl2.
The chemical characterization of untreated and treated coir fibres was done by determining the content of extractives, lignin, and holocellulose.
The inhibition test graded the untreated fibre as “extreme inhibition,” ratifying the need to provide it a treatment.
Treatments done on coir fibres affected positively the compatibility between cement and fibre, reducing the inhibition.
The treatments reduced the lignin coir fibres’ and extractives proportion, whose variation was significantly correlated with the reduction of the inhibitory index.
These results indicate a possibility for future incorporation of these fibres into the production of mineral composites.
