Hydration regulation type expansion chamotte and preparation method thereof
The invention discloses a hydration regulation type expansion chamotte and a preparation method thereof; the hydration regulation type expansion chamotte comprises 65-80 parts of limestone, 5-15 partsof gypsum, 2-5 parts of iron slag, 4-15 parts of alumina, and 7-20 parts of non-metallic oxide or non-metallic oxide composite metal oxide; the preparation method provided by the invention is simpleand easy to implement, and the cost is low. The obtained expanding agent chamotte is high in expansion energy, keeps continuous expansion for 1-14 days under the curing condition of 40-60 DEG C, is matched with the temperature drop shrinkage stage and the drying shrinkage stage of concrete at the same time, and has no later delayed expansion, so that the expansion hydration has adjustable and controllable performance; the preparation process is simple, green and environment-friendly, and the purposes of reducing the early temperature of concrete and drying shrinkage cracks can be better achieved.
本发明公开了一种水化调控型膨胀熟料及其制备方法，该熟料包括石灰石65～80份、石膏5～15份、铁渣2～5份、矾土4～15份，还包括7～20份非金属氧化物或非金属氧化物复合金属氧化物，本发明提供的水化调控型膨胀熟料，制备方法简单易行，所得膨胀剂熟料的膨胀能高，并且在40～60℃养护条件下，在1～14天保持持续膨胀，与混凝土的温降收缩、干燥收缩阶段同时间匹配，并且无后期延迟膨胀，使膨胀水化具有可调控性能；制备工艺简单，且绿色环保，可以更好地达到减少混凝土早期温度、干燥收缩裂缝的目的。
