配合比的主要参数对掺MgO水泥基材料压蒸膨胀变形的影响
Influence of mix factor on autoclave-treated expansibility of cement-based materials mixed with magnesium oxide
摘要
Abstract
This paper presents test results of autoclave-treated expansibilities of cement paste,cement mortar and mortar in concrete with light-burned magnesium oxide.Based on these results,the influences of mix factors on autoclave-treated expansibility are analyzed.Results show that for cement-based materials the expansibility is increasing with decreasing of water/cement ratio or increasing of magnesium oxide,while for mortar in concrete,it is decreasing with fly ash content increasing and it depends on cementation material/ sand ratio.This work provides a basis for farther study on the exploitation of concrete materials mixed with magnesium oxide.关键词
