    摘要：将高吸水聚合物型内养护剂应用于C30和C60混凝土中，研究了内养护剂用量、养护条件对混凝土抗裂性能和强度的影响。结果表明：内养护剂掺量为0.1%时，对低水胶比的C60高强混凝土效果明显，可显著提高混凝土的力学性能；明显提升混凝土的抗开裂性能。

    Abstract：By applying the high water absorbing polymer type curing agent to the concrete with strength grade of C30 and C60，this paper studied the effect of curing agent amount，curing condition on the crack resistance and strength. The experimental results show when the optimum dosage of the inner curing agent is 0.1%，the effect to the C60 high strength concrete with low water-binder ratio is obvious，which can significantly improve the mechanical properties of concrete. And cracking resistance performance of concrete can also be improved significantly.
