摘要：高性能混凝土由于其低水胶比和高胶凝材料用量，易产生收缩开裂现象。采用内养护可以改善混凝土内部的湿度场，提高混凝土内部的含湿量，从而有效地控制混凝土收缩裂缝的产生。本文阐述了国内外内养护技术的现状，分析了内养护技术的作用机理，以及内养护材料的选择，总结了饱水轻集料（LWA）和超强吸水剂（SAP）两类内养护材料对混凝土性能的影响。 Abstract：High performance concrete is easy to happened to lead to the early shrinkage-cracking due to its low W/C and the high content of cementitious materials. The inner curing(IC) can improve the internal humidity of concrete, which can effectively solve the problem of early shrinkage-cracking. In this paper, the current research situations of IC technologies are discussed，and the mechanism of the inner curing, as well as the materials selection, are analyzed. The effect of water-saturated lightweight aggregate(LWA) and super-absorbent polymer (SAP) on the performances of concrete are summarized based on review of many relevant literatures.

Abstract：High performance concrete is easy to happened to lead to the early shrinkage-cracking due to its low W/C and the high content of cementitious materials. The inner curing(IC) can improve the internal humidity of concrete, which can effectively solve the problem of early shrinkage-cracking. In this paper, the current research situations of IC technologies are discussed，and the mechanism of the inner curing, as well as the materials selection, are analyzed. The effect of water-saturated lightweight aggregate(LWA) and super-absorbent polymer (SAP) on the performances of concrete are summarized based on review of many relevant literatures.
