熟石灰粉就是氢氧化钙（qīng yǎng huà gài）它的基本用途是用于制漂白粉，硬水软化剂，改良土壤酸性，自来水消毒澄清剂及建筑工业等。
纤维素醚和熟石灰粉都能改善砂浆的泌水，考虑到砂浆的流动性和强度，选择熟石灰的掺量2%；
HPMC and hydrated lime powder could improve the bleeding, taking into account the fluidity and strength choose the content of hydrated lime is 2%.
然而，矿粉结合料比为1.5时，由于添加熟石灰后试件太硬无法拌和，因此沥青胶浆的工程性质无法测试。
However, engineering properties for hydrated lime asphalt mastics at 1.5 dust to binder ratio, couldn't be tested because the specimens were too stiff to mix at this ratio.
