Availability of nano additives in cementitious composites

Technological developments in recent years have given the opportunity to examine materials in the smallest dimensions and have created significant effects in the field of building materials. Thanks to nano technology, nano-featured binder materials have improved many properties of cement-based materials such as workability, strength and durability, allowing them to be used for different purposes. By adding tungsten carbide to the mortar samples produced within the scope of this study, it is aimed to obtain the necessary scientific data for the application, especially to improve the strength and durability properties of the mortars, and to contribute to the development of many areas such as construction materials. In the study, samples were produced by adding 0.25, 0.5, 0.75 and 1 percent tungsten carbide to the mortars by weight of cement. Ultrasound transmission velocity, flexural strength, compressive strength, water absorption, electromagnetic shielding tests and SEM analysis were carried out on the produced mortar samples. As a result of this study, flexural strength values increased with increasing tungsten carbide ratio. The addition of tungsten carbide also increased the ultrasound transmission rate.
