Abstract

Concrete is one of the most widely used materials in construction, and the reason for that is its hardness, durability and high resistance. Pores are usually filled with fluid. So far, nanostructures with regular and irregular shapes have been made from different materials, which in total form one of the most diverse categories of materials. In this regard, 30 samples were made and tested for compressive strength testing and 30 samples for tensile testing. The amount of nanosilica and nanoclay in three different ratios of 0.25, 0.50, and 0.75 of cement weight has been added to the concrete mixture. The obtained results show an increase in the compressive and tensile strength of concrete due to the addition of nanosilica and nanoclay
