Different dosage fly ash were added in concrete to reduce the amount of cement in order to reduce the heat of hydration of concrete and improve the concrete's tensile strength or ultimate tensile deformation. Mechanical tests of differ-ent fly ash concrete were carried. The test results showed that the fly ash on the properties of fresh concrete had a good im-provement effect.
