The term cement originates from the Latin word caementum, which refers to chopped stone. Cement describes a substance which will react chemically with water and develop into a material as hard as stone. In fibre cement there is a fibre reinforcement, which contributes to making the fibre-cement material even stronger.
Plant fibers are a promising area but they are subjected to degradation in the alkaline environment and elevated temperatures during cement hydration. [3] [4] In international literature, FRCMs are also called textile-reinforced concrete (TRC), textile reinforced mortars (TRM), fabric-reinforced mortar (FRM), or inorganic matrix-grid composites ...
LC (plant-based) fibers and particles can degrade in a cement matrix [22] [23] Blends of both steel and polymeric fibers are often used in construction projects in order to combine the benefits of both products; structural improvements provided by steel fibers and the resistance to explosive spalling and plastic shrinkage improvements provided ...
This occurrence is hindered by the presence of fiber bridging, a property that most HPFRCCs are specifically designed to possess. Fiber bridging is the act of several fibers exerting a force across the width of a crack in an attempt to prevent the crack from developing further. This capability is what gives bendable concrete its ductile properties.
Cement bonded particle boards have treated wood flakes as reinforcement, whereas cement fibre boards have cellulose fibre, which is a plant extract as reinforcement. Cement acts as binder in both the cases. The fire resistance properties of cement bonded blue particle boards and cement fibre boards are the same. In terms of load-bearing ...
