碱—碳酸盐骨料反应及膨胀机理和抑制效果探讨

A study on Alkali-Carbonate Aggregate Reaction

本文根据宝珠寺水电工程人工骨料料场粘土质白云岩夹层岩样碱一碳酸盐反应的试验鉴定结果，结合有关资料对其膨胀机理提出了探讨性意见。并综合评述了抑制碱一碳酸盐骨料反应的措施。

Based on experimental results of aggregate materials sampled ftom artificial aggregate plantin Baozhusi hydropower station,some aggregate material,such as dolomite with clay,was of alkali-carbonate reaction. Referring to exporimental results in the existing literatures,the mechanism ofexpansion was inveeti gated and the meastures for controlling alkali-carbonate reaction were also suggested in this paper.
