Fiber cement flat sheets are a type of building material crafted from a mix of inorganic hydraulic or calcium silicate binders, formed through a chemical reaction of calcareous and siliceous elements, bolstered by synthetic fibers, both organic and inorganic.
These sheets are designed for outdoor applications, enduring direct exposure to sunlight, rain, and snow. They can be purchased with or without coatings.
Intended for indoor use or outdoor spaces shielded from direct weather conditions.
These sheets come in lengths up to 3000 mm and widths up to 1240 mm.
Typically available in thicknesses ranging from 3 to 9 mm, with preferred options being 3, 4, 4.5, 5, 6, and 9 mm.
This test evaluates the sheet’s resistance to bending forces. Results must meet specified modulus of rupture values, as outlined. The mean modulus of rupture under wet conditions must be at least 50% of the mean modulus of rupture under equilibrium conditions.
Ensures sheets resist water penetration. Moisture traces are permissible, but water droplets should not form on the underside.
Determines if sheets can withstand freeze-thaw cycles without significant damage. The average ratio after 50 cycles should not fall below 0.75.
Evaluates the sheet’s reaction to warm water exposure, with the limit (L) needing to exceed 0.75.
Assesses the sheet’s performance when subjected to cycles of soaking and drying, with the limit (L) again needing to exceed 0.75.
Tests the sheet’s durability under simulated heat and rain onditions, ensuring no visible defects that could impact performance.
