Ageing behaviour of cellulose fibre cement composites in natural weathering and accelerated tests

Akers, S.A.S. / Studinka, J.B.

AbstractThe ageing behaviour of two types (naturally cured and autoclaved) of cellulose fibre reinforced cement products have been evaluated independently and compared. Two accelerated ageing test methods have been studied and direct comparisons drawn with ageing in natural weathering. In essence it has been found that the accelerated ageing test method in a CO2 rich environment appears to simulate the ageing mechanism found in natural weathering, and can be used successfully for durability studies concerned with cellulose fibre products. The ageing behaviour of the products studied may be summarised as an increase in flexural strength and E-modulus of the composite with age. It is suggested that this change in mechanical property development may be a result of, amongst others, carbonation of the matrix, increase in the interfacial bond and change in the reinforcing potential of the cellulose fibres with age.
