Use of piezoelectric materials in cement based composites

With the increasing use of piezoelectric materials in many different fields, there is a need for more comprehensive research and examination. This trend towards piezoelectric materials has turned the attention to the field of civil engineering. The development of cement-based piezoelectric materials is encouraged to enable more efficient use of piezoelectric materials. By adding barium titanate to the mortar samples produced within the scope of this study, it is aimed to improve the strength and durability properties of the mortars and to contribute to the development of the building material field. In addition, as a result of this study, it will be presented as a solution proposal to the rapid development of many fields, especially building materials, and energy need problems in the next generation, by improving the properties of piezoelectric materials, which have an important place in renewable energy, and reducing their costs. The study will be beneficial both in the use of a new material in the construction sector, in the development of a product that is extremely important in terms of environment and technology use, and in the use of the product. In the study, samples were produced by adding 0.25, 0.5, 0.75 and 1 percent barium titanate to the mortars by weight of cement. Ultrasound transmission velocity, bending strength, compressive strength, water absorption, electrical resistance, electromagnetic shielding tests and SEM analysis were performed on the produced mortar samples. As a result of this study, it was observed that the flexural strength and ultrasound transmission velocity values increased up to the 0.25% doped BT2 sample and then decreased. According to the results of the water absorption test, barium titanate increased the water absorption capacity. It was concluded that with the increase in barium titanate usage rates, the electrical resistivity values increased and thus the conductivity decreased.
