Advanced technological knowledge, highly influences the achievement of the strong, sturdy and good quality of construction targets. Nanotechnology becomes a massive concern to the scientists around the world in conducting various research and engineering the adjustment of material, size, managing the chemical composition and controlling the interactions between particles. One of them is a nano scale research which is widely applied to nanocomposite materials. The nano-sized particles have a very high interaction surface. The more particles interact, the stronger bond of the material. It makes the bonds between the particles get stronger and the mechanical properties of the material increase. However, the addition of nanoparticles does not always improve its mechanical properties.
*Author for correspondenceThere are certain limitations when adding the nano material, the strength actually decreases. Epoxy resin is defined as a low molecular pre-polymer containing more than one epoxide group. Epoxy resin is an epoxy oligomer, which can form a three-dimensional network of thermosetting materials when it reacts to hardeners [1]. Epoxy is resistant to heat, it has higher mechanical strength and has good corrosion resistance [2]. Epoxy can be used as a material for repairing and connecting the rifts of concrete structures, the plaster layers in brittle concrete structures, and the water proof [3]. Epoxy reacts very easily with hardener when it is mixed, there is a change from initially liquid to solid. With the addition of nanocalcium, epoxy resin and hardener can increase the thermal stability of the material [4]. Epoxy resin is often used as a mixture for glass fiber, carbon, hybrid, and boron graphite. Epoxy resin has several advantages than the polyester resin, such as lower density, higher modulus of elasticity,
