“…CSIP's facings are made of composite materials which make it considerably stronger, immune to biological corrosion and more durable to weather conditions. Such desirable improvements, in comparison to traditional SIPs, make CSIPs a very attractive alternative with a broader field of applications [16][17][18][19][20][21]. Increased strength of this type of sandwich makes it a viable option even in bridge structures [22][23][24].…”

Abstract. Sandwich panels are readily used in civil engineering due to their high strength to weight ratio and the ease and speed of assembly. The idea of a sandwich section is to combine thin and durable facings with a light-weight core and the choice of materials used allows obtaining the desired behaviour. Panels in consideration consist of MgO (magnesium oxide) board facings and expanded polystyrene core and are characterized by immunity to biological corrosion, a high thermal insulation and a relatively low impact on environment. Customizing the range of panels to meet market needs requires frequent size changes, leading to different failure modes, which are identified in a series of costly full-scale laboratory tests. A nonlinear numerical model was created with a use of a commercial ABAQUS code and a user-defined procedure, which is able to reproduce observed failure mechanisms; its parameters were established on the basis of small-scale tests and numerical experiments. The model was validated by a comparison with the results of the full-scale bending and compression tests. The results obtained were in satisfactory agreement with the test data.

“…It consists of insulating polymer foam sandwiched by two layers of structural skins. Two layers of skins can be metal sheet, plywood sheet, magnesia cement board [1], thermoplastic laminate [2], fiber cement sheet and oriented strand board [3] etc. The foam can be either Extended Polystyrene (EPS), extruded polystyrene foam (XPS) or polyurethane foam (PU), etc.…”

“…There are many different types of composite sandwich panels that can be constructed, but one of the stronger types of sandwich panels is a panel made of a polystyrene/cement core that is sandwiched between thin cement sheet facings [10]. The structural properties of sandwich panels constructed of polystyrene/cement cores and thin cement sheet facings are relatively unknown [11]. Therefore, there are a number of questions that could be asked such as how the stress acts within the panel under loads?…”

Sandwich panels are made of two materials that are relatively weak in their separated state, but are improved when they are constructed together in a sandwich panel. Sandwich panels can be used for almost any section of a building including roofs, walls and floors. These building components are regularly required to provide insulation properties, weatherproofing properties and durability in addition to providing structural load bearing characteristics. Polystyrene/cement mixed cores and thin cement sheet facings sandwich panels are Australian products made of cement-polystyrene beaded mixture encapsulated between two thick cement board sheets. The structural properties of sandwich panels constructed of polystyrene/cement cores and thin cement sheet facings are relatively unknown. Therefore, in this study, to understand the mechanical behaviour and properties of those sandwich panels, a series of experimental tests have been performed and the outcomes have been explained and discussed. Based on the results of this study, values for modulus of elasticity and ultimate strength of the sandwich panels in dry and saturated conditions have been determined and proposed for practical applications.
