Modified aggregate, preparation method thereof and concrete applying modified aggregate
The invention relates to the field of concrete, in particular to modified aggregate, a preparation method thereof and concrete applying the modified aggregate. The modified aggregate comprises aggregate and an ionic liquid-like phase change energy storage modifier, and the ionic liquid-like phase change energy storage modifier is located in pores in the surface of the aggregate; and the ionic liquid-like phase change energy storage modifier comprises an ionic liquid-like material with a phase change temperature range of 20-38 DEG C. The preparation method comprises the following steps: dipping: dipping the aggregate in a liquid ionic liquid-like phase change energy storage modifier to enable the ionic liquid-like phase change energy storage modifier to enter gaps of the aggregate, taking out the aggregate, and cooling the aggregate to a saturated surface dry state; slurry wrapping: wrapping the surface of the aggregate in the saturated surface dry state with cement-based slurry, forming a layer of shell, and preparing the modified aggregate. Concrete prepared from the modified aggregate has good heat preservation and energy storage effects, and a concrete product prepared from the modified aggregate has good strength.
本发明涉及混凝土领域，尤其是一种改性骨料及制备方法和应用其的混凝土。改性骨料是包括骨料与类离子液体相变储能改性剂，所述类离子液体相变储能改性剂位于骨料表面的孔隙中；所述类离子液体相变储能改性剂包含相变温度范围为20‑38℃的类离子液体。在制备时，包括以下步骤：浸渍：将骨料浸没在液体状的类离子液体相变储能改性剂中，以使类离子液体相变储能改性剂进入骨料的空隙中，取出后冷却至饱和面干状态；裹浆：将呈饱和面干状态的骨料表面包裹水泥基浆体，形成一层外壳，制得改性骨料。使用该改性骨料制得的混凝土具有较好的保温储能效果，且其制得的混凝土制品的强度较好。
