The Effect of Graphene Powder on High Strength Concrete Prepared with Fly Ash

Considering the increase in the price of concrete raw materials, especially cement, and the damage caused by its production to nature and the resulting pollution, it is the duty of engineers and administrators to seek the most optimal materials with long service life in concrete structures. In this regard, considering the topic of the thesis, we were trying to produce high-strength concrete to increase the service life of the structure in the first stage and in the next stage to test the use of recycled materials from coal-fired power plants that are buried as waste in nature. In this research, we have used ۵% fly ash, and to increase the strength of the concrete, graphene has also been used in ۰.۵, ۱, ۱.۵, and ۲%. Due to the laboratory nature of the samples, we have used standard silica sand and lubricant. To conduct compressive strength tests, water absorption, and carbonation in ۷, ۲۸, and ۹۰ days, ۱۸۰ ۱۰-centimeter cubic samples were prepared and the required tests were performed on them.
