“…As for rock and ordinary concrete, the slope of the secant between point A and point B should be chosen as the testing elastic modulus. The testing results of σ A /σ max and σ B /σ max are listed in table 3. As the testing result shows that the σ A /σ max and σ B /σ max of AAC is about 30%, 80% respectively, the value of latter is 10% higher than that of normal concrete, namely the AAC elastic modulus calculated value should take stress extreme value of 30% -80% is reasonable.…”

“…Therefore, AAC has been widely used as building cladding, vibration isolation filling material. The AAC and its properties of material mechanics are the research achievements of rich manufactured goods [1][2][3][4][5] . But the strain rate effect of AAC study is less, the whole process of the nature of investigation under dynamic loading condition is the lack of adequate experimental data.…”

A total of 60 cylindrical specimens with density of 425 kg/m 3 , 525 kg/m 3 , and 625 kg/m 3 , subjected to uniaxial compression were tested, under four different strain rates ranging from 10-5 /s to 10-2 /s. 15 specimens designed and casted on the same condition were tested for every set of case. The mean and standard variation values of the uniaxial compressive stress-strain curves, as well as the statistical characteristic values of compressive stress and peak strain of concrete with different strength under different strain rates, were obtained through experiments. The results indicate that the strain rate has a significant influence on the stress-strain mean value curves.

“…In order to reduce the effects of thermal mass transfer in PCSP, many research works have taken the option of using alternative materials that have low thermal conductivity such as carbon fibre reinforced polymer (CFRP) [39][40][41], Basalt fibre reinforced polymer (BFRP) [23,42,43], and Glass fibre reinforced polymer (GFRP) [44][45][46][47][48][49][50][51]. Theoretically, the structural behaviour and thermal performance of fibre reinforced polymers depends on their chemical composition.…”

Precast concrete sandwich panels (PCSP) are energy efficient building system that is achieved through an insulation layer created between the concrete wythes. The insulation layer is usually of low bearing strength material making it more applicable for non-structural building systems. Hence, shear connectors are introduced to improve its structural capacity, which subsequently degrades it thermal performance by serving as thermal bridges across the panel. This article review researches of alternative materials and methods used to improve the thermal efficiency as well as reduced the strength loss due to insulation in PCSP. The alternative materials are basalt fibre reinforced polymer (BFRP), carbon fibre reinforced polymer (CFRP), glass fibre reinforced polymer (GFRP), and foam concrete which are selected due to their low thermal conductivity for use in shear connection. While thermal path method has been used to prevent the effect of thermal bridges. Although, some of these materials have successfully achieved the desirable behaviours, however, several undesirable properties such as brittleness, bond slip, the sudden crushing of the panel system, and FRP failure below its ultimate strength were observed. Hence, the practicality of the alternative materials is still questionable despite its higher cost compared to the conventional steel and concrete used in the PCSP system.

“…Therefore, in nonlinear range the contribution of AAC in compressive forces is considered none. [8] So the equilibrium equation becomes V= V frp (4) Shear provided by CFRP is 26981.9. Shear provided by BFRP is 22752.6.…”

Abstract. The structural behavior of fiber-reinforced polymer (FRP) reinforced autoclaved aerated concrete (AAC) panels has been investigated. Four FRP/AAC panels and two non FRP AAC panels were prepared for testing. The panels were tested under four-point bending test to investigate their strength and displacement of mid-span responses using a bending pressure testing machine. Experimental results showed that FRP laminates increased the bearing capacity of AAC panels. A theoretical analysis was conducted to predict the strength of the FRP/AAC member, and the results found were in good accordance with the experimental results.
