采用天然碱活性石灰质骨料,按照快速砂浆棒法(ASTM C1260),研究了天然沸石分别与粉煤灰、矿渣和硅灰的复合对碱-硅酸反应(ASR)的影响。结果显示,沸石与其他矿物质掺合料的复合对ASR的抑制效果与沸石的品质及其他矿物质掺合料的品质有关。
The effect of the combination of natural zeolite with fly ash, slag and silica fume on the alkali-silicic acid reaction (ASR) was investigated using a trona active limestone aggregate according to the rapid mortar bar method (ASTM C1260). The results show that the combination of zeolite and other mineral admixtures has an inhibitory effect on ASR that is related to the quality of the zeolite and the quality of other mineral admixtures.
