水泥石的膨胀行为与应力匹配

采用膨胀自动测定仪和电阻应变仪测定了水泥石的膨胀率和膨胀应力，研究了游离氧化钼在不同温度条件下对水泥石膨胀行为的影响规律，发现水泥石的膨胀行为实质上反映了其内部的应力匹配，它不仅与膨胀组分的含量和活性有关，以取决于水泥石自身的结构的粘聚应力。

Expansion Behavior and Stress Match of Hardened Cement Pastes

The expansion ratio and expansion stress of hardened cementpaste(hcp) are determined by expansion measurer with automatograph and straingauge. The effects of free lime on the expansion behavior of hcp were studiedunder various temperatures. It is found that the expansion behavior of hcp reflectsits inner stress match. It relates not only to the content and reactivity ofexpansion constituent, but also to the cohesive stress of hcp.
