“…The extruded panels satisfied all performance requirements related to fire resistance. Abdellahi and Hejazi [22] used WSP to fabricate cementitious composite panels reinforced with glass and polypropylene (PP) fibers. Experimental results showed that the use of WSP increases both flexural and compressive strength.…”

In this study, the influence of 3D fabric on the flexural behavior of cementitious composites has been investigated. Three 3D fabric samples were produced with different spacer yarn orientation angles of 65°, 55°, and 47°. The cementitious matrix was fabricated by cement and waste stone powder. After casting of all samples, flexural test was carried out on all specimens. Results showed that cementitious sample reinforced by 3D fabric with less spacer yarn orientation angle proposed the highest flexural strength among all samples (reinforced and unreinforced samples). Moreover, finite element method was used to predict the flexural behavior of textile reinforced concrete. Finite element method results showed good agreement with the experimental data. Consequently, the maximum spacer yarn stress derived by finite element analysis was used to calculate the efficiency reinforcement factor for all the textile reinforced concrete samples.

Thermal behavior such as heat transfer is an important parameter for construction composites. Three-dimensional textile reinforced concrete (TRC) is one of the construction composites which is recently being used in the building industry. Therefore, in this study, the thermal behavior of three different TRC samples was investigated by a heat transfer test using an infrared method. The cementitious matrix was reinforced by 3D fabric with three different spacer yarn orientation angles. The cementitious matrix was fabricated by cement and waste stone powder. The TRC sample was put on the hot plate of the heat transfer apparatus and the temperature variations of the top surface of the sample were obtained. According to the test results, increasing the orientation angle of spacer yarns leads to a decrease in the thermal conductivity of the TRC sample and reduces heat transfer. On the other hand, a theoretical model was used to calculate the thermal conductivity and resistance coefficients of sandwich samples. Furthermore, a 3D finite element model was used to predict the heat transfer of TRC specimens. A unit cell of the TRC model was created in Abaqus software and finite element (FE) analysis was carried on a created model. Thermal conductivity and thermal resistance of samples according to FE results were calculated and compared with experimental results. FE results showed good agreement with the experimental data.

“…Concrete is one of the cement products used in many parts of construction, such as buildings, bridges, tunnels, and roads. Studies show that the cement industry demands a vast amount of energy and also releases a large amount of carbon dioxide into the atmosphere-up to 13,500 tons per year, which is 7% of greenhouse gas emissions annually produced and causes additional environmental pollution [1,2]. erefore, many scholars are currently devoted to the study of cement alternative materials.…”

Concrete materials are an important part of global structure, and their fire resistance directly affects the safety of buildings and tunnels. In this study, basalt fiber was used to reinforce concrete with high content of stone powder in order to enhance its high-temperature performance. The mechanical properties and ultrasonic characteristics at different temperatures were studied using the cube compressive strength test and nonlinear ultrasonic test. The results indicated that the addition of basalt fiber in specimens improved their compressive strength; however, this strength did not continuously increase with increases in the fiber length and fiber content, and the optimal values for fiber length and fiber content were determined to be 12 mm and 1 kg/m3 at 600°C, respectively. With increases in temperature, the unconfined compressive strength increased first and then decreased. When the temperature was 400°C, the unconfined compressive strength of the specimens reached their highest values and then decreased. When the temperature was 400°C and 600°C, the strength of the stone powder concrete with fiber was higher than that without fiber, which shows that fiber can improve the mechanical properties of concrete at high temperatures. Based on the Box-Behnken design (BBD) method, the unconfined compressive strength response regression model of basalt fiber-reinforced concrete with high content of stone powder, which follows parameters including fiber content, fiber length, and temperature at high-temperature environments, was established, and it was found that the interaction of fiber content, fiber length, and the temperature was significant based on multifactor interaction analysis. The analysis of ultrasonic signals based on the S transform showed that, with increases in temperature, the amplitudes of the acoustic response signals, the corresponding frequency spectrum, and the time-frequency spectrum were clearly reduced. At the same temperature, the amplitudes of the acoustic response signals of different concrete testing blocks did not change much and remained at the same level.
