critical hardening
解釋
臨界淬火-
The harmonic factor raises with the growth of volume percentage of hardening particles no mater what detecting direction is. but it is not a linear variation course. the harmonic factor mounts up slowly under the critical value but increases rapidly while exceeds the critical value
在正、逆向檢測時,隨著強化粒子體積百分數的增加,在有效頻帶范圍內諧波系數同時單調增加,但其變化是非線性的,即在臨界值以下,諧波系數的變化趨于平緩,而超過臨界值以後,隨著強化相粒子體積百分數的增加,諧波系數快速增加。 -
Calcium - enriched fly ash debases the numerical value of critical strength of frozen injury and improves the microstructure because of its form effect, activity, tiny aggregate effect and self - hardening property. so it is feasible to make it an important component of minus - temperature concrete
因為增鈣粉煤灰具有形態效應、活性效應、微集料效應和自凝性、自硬性等優勢,它改善了混凝土的微觀結構,降低了負溫混凝土的抗凍臨界強度,所以增鈣粉煤灰可以作為負溫混凝土的摻合料。
