摘要
硫铝酸钙-氧化钙-硫酸钙复合膨胀剂是目前应用较为广泛的混凝土膨胀剂,氧化镁膨胀剂是新型混凝土膨胀剂。本文着重介绍了这两种混凝土膨胀剂在不同水化条件下的产物种类、形貌和特性的研究现状,并在此基础上提出在膨胀剂作用机理方面未来的研究方向。
The C_4A_3S|-CaSO_4-CaO expansive agent is widely used for shrinkage compensating in construction nowadays,while the MgO expansive agent is relatively new. The morphologies and performances of hydration products of these two types of expansive agent were reviewed in this paper. Based on the review,The further research directions of the reaction mechanism of expansive agents were proposed.
