1 Introduction</h5> Cement composite has been used as a construction material because it is advantageous economically and has excellent mechanical properties, such as compressive strength, durability, and rigidity. However, it has the disadvantages of relatively low tensile, flexural, and impact strength, and it exhibits brittleness and low energy-absorption capacity [3–6] .</P>The evaporation of water from cement composites while they are in a plastic state, along with the water loss that accompanies hydration, can result in a volume reduction of over 1% of the absolute volume in dried cement [6,18] . When the rate of water loss exceeds 0.5 kg/m 2 /h, especially from very young cement composites, tensile stresses can arise from external or internal restraints  . As a result, plastic shrinkage cracking may occur at the point at which the tensile stress exceeds the cracking strength of the cement composites [3,4,18] . In the case of the plastic shrinkage cracks, which can occur in the early hardening of cement composite, cracks destroy the surface area of the composite, making the penetration of external deteriorating material easier, which decreases durability. One of the methods for preventing plastic shrinkage cracks is to introduce curing, which can prevent water
