Abstract The measures of steam curing and early-strengthening agents to promote the precast components to reach the
target strength quickly can bring different degrees of damage to the concrete. Based on this, the new nanomaterial
CSH-the hydration product of cement effectively solves these measures’ disadvantages, such as excessive energy
consumption, thermal stress damage, and the introduction of external ions. In this paper, the effect of CSH on the
early strength of precast fly ash concrete components was investigated in terms of setting time, workability, and
mechanical properties and analyzed at the microscopic level using hydration temperature, XRD, and SEM. The
