“…This happens because of intrinsic quality of natural fibre that can improve the tensile strength but not the compressive strength. Chakartnarodom et al [23] asserted that the bond strength between fibre and matrix does affect the composite behaviour. It was proven as the Modulus of Rupture and Modulus of Elasticity have increased compared to plain cemboard.…”

“…Furthermore, steel frame with thicker fibre cemboard panel showed a higher lateral load carrying capacity which is around 4.5 times greater than steel frame with mortar [33]. This is caused by an additional bond strength from the presence of fibre compared to plain mortar [34]. On the other hand, fibre cemboard panel is relatively weak in resisting bending [14].…”

The fabrication of precast slab can be made from wide range of material either neat concrete, foamed concrete or even composite. Until recently, a new interest has been discovered. Instead of wet concrete mixing process in plant, the precast slab can be substituted with fibre cement board or commonly referred as cemboard that meets the specific load requirements with minimum thickness. However, cemboard panel is preferable for lightweight floor system due to its physical strength limitation. Its thickness that relatively small around 15 mm to 25 mm contribute to the drawback and subsequently prohibited the application of cemboard panel as heavyweight floor system. Small specimens are prepared to determine the optimum orientation of bolts and type of bond by analysing the bearing resistance and bond-slip behaviour. It was found that the bearing capacity is governed by polyurethane glue. Meanwhile, the bond-slip behaviour is effectively controlled by the steel bolt. If the steel bolt is solely used as bond mechanism, the bearing capacity will rely on its quantity and capacity and increasing the quantity of steel bolt will eventually lead to the higher value of bearing resistance.

“…Generally, the raw materials for manufacturing the fiber-cement composites are Portland cement, silica sand, fibers, additives, and water. These raw materials are mixed and molded into the green sheets by a process such as filter pressing, Hatschek process, Magnani process, injection molding, extrusion, mold casting, flow-on process, and roll forming [2][3][4]. Regularly, the additives are used in fiber-cement composites for reducing the amount of water for the forming process and/or improving the properties of the finished products.…”

The aim of this work was to reduce the water absorption of the fiber-cement composites, which is also known as fiber-cement products, by the crystal modification of cement matrix using the additives including polyurethane-based corn starchâ€“lithium perchlorate (LiClO4), and acrylic resin emulsion-based chitosan-silicate hybrid compound. To prepare the samples, the mixtures consisting Portland cement Type I, sand, cellulose fibers from pine trees, gypsum, and additive were mixed with water. The percentages of additive in the mixtures before mixing with water were 0.03 to 0.17 wt%. The green sheets of samples were formed by filter-pressing method, air cured for 1 day, and then autoclaved at 8 bars and 140Â°C for 12 h. The experimental results indicated that the water absorption of the samples was reduced when polyurethane-based corn starchâ€“lithium perchlorate (LiClO4) was used as the additive due to the crystallization of the small crystals within cement matrix, while their mechanical properties including modulus of rupture (MOR) and modulus of elasticity (MOE) of the samples using this additive conform industrial standard.

“…The 28-days strength by normal curing for FRCC sheets could be achieved after autoclave curing. Even though the FRCC cured by the autoclave has desirable properties, this requires a high capital investment for the machines and the energy used during the operation [12][13][14][15][16][17].…”

Fiber-reinforced cement composites (FRCC) are widely used in the construction of houses and commercial buildings in many countries such as the United States, the United Kingdom, the European countries, and the Asian countries such as China, India, and Thailand. Conventionally, the FRCC is manufactured from Portland cement, silica sand, and cellulose fiber using the so-called autoclaved curing under a designate hydrothermal condition to accelerate the hydration reaction resulting in superior properties. However, the autoclave-curing process needs a huge investment and generates highly environmental impact specially greenhouse gases due to its heavy energy consumption. Hence, this research aims to develop the FRCC with lowering embodied energy via the energy-free moisture curing process. The use of different crystal modifiers (CM) including synthetic tobermorite, alumino-silicate complex, and modified lithium compound in addition of the usual FRCC composition to drive the hydration kinetic and then properties achieved were characterized by the relevance of higher heat of hydration. Moreover, scanning electron microscope (SEM) were used to reveal the favorable effects of appropriate CM through the microstructure. The results approved that the FRCC with qualified mechanical performance and densified microstructure was successfully produced by using the appropriate moisture curing condition and CM. Additionally, using alumino-silicate complex as CM at 3% of cement weight produced FRCC with the highest modulus of elasticity of 9,067 ± 492 MPa, and the lowest % water absorption of 27.42 ± 1.65 %.
