Temperature control type concrete expanding agent
The invention discloses a temperature control type concrete expanding agent, which comprises an expanding and compacting component and a temperature control component, wherein the expansion compactioncomponent is composed of hydration regulation type calcium oxide calcium sulphoaluminate expansion clinker, gypsum and silica fume; the raw materials of the hydration regulation type calcium oxide calcium sulphoaluminate expansion clinker consist of limestone, gypsum, iron slag, alumina and non-metallic oxide or a compound of the non-metallic oxide and metal oxide. The temperature control component comprises an inhibiting component and an adjusting component, which achieve a synergistic effect to adjust internal hydration heat, temperature peaks and temperature peak appearing time of cement paste and concrete. According to the expanding agent, the expanding reaction rate can be reasonably regulated and controlled at normal temperature and 40-60 DEG C, the hydration reaction rate of a cement-based material is reduced and delayed, and the cracking phenomenon of a concrete structure due to overlarge temperature stress is reduced.
本发明公开一种温控型混凝土膨胀剂，包括膨胀密实组分和温控组分；膨胀密实组分由水化调控型氧化钙‑硫铝酸钙膨胀熟料、石膏、硅灰组成；所述的水化调控型氧化钙‑硫铝酸钙膨胀熟料的生料由石灰石、石膏、铁渣、矾土，以及非金属氧化物或非金属氧化物和金属氧化物的复合物组成；温控组分包括抑制组分和调节组分，两者协同作用调节水泥净浆、混凝土的内部水化热、温峰和温峰出现的时间。本发明提供的膨胀剂，不仅在常温下，还能在40～60℃下对膨胀反应速率进行合理调控，降低、延缓水泥基材料的水化反应速率，降低混凝土构筑物因温度应力过大的开裂现象。
