| Abstract | This study is aimed at investigating the feasibility of
using randomly distributed short sisal fiber reinforced cement
mortar composite as low cost roofing material for tropical
countries. The fiber content and compacting or casting pressure
were the main parameters varied in _ order to obtain the optimum
material. Bending, impact resistance, water absorption, water
tightness, shrinkage, fire resistance and exposure tests were
performed in accordance with the relevant ASTM standard and
Industrial Product Standard where available.
Test results showed that a composite with a fiber length of
25 mm . , a fiber content of 2 % and casting pressure of 0.12 MPa
was considered to be the optimum composite. The bending
resistance and deflection at ultimate load obtained for sisal
fiber
roofing
roofing sheets are less than that of asbestos
sheets. The sisal fiber roofing sheets
corrugated
exhibit
impervious, fire resistance properties and possess adequate
durability in the short term. On a material cost basis, the
composite can be considered a low cost alternative to corrugated
galvanized iron and asbestos cement sheeting. |
