This paper presents an experimental investigation on the slump and physical properties of concrete reinforced with GO nanosheets at additions from 0.00% to 0.08% by weight of cement and a water–cement ratio of 0.5. The study demonstrates that the addition of GO nanosheets improves the compressive strength, flexural …
The properties of cement can be divided into two categories, the first being the physical properties of cement, and the second being the chemical properties of cement. The cement performance mainly depends on its composition, raw materials, and the attention paid during the combustion and grinding process.
