Alumina-silicon carbide-carbonaceous cement-free castable suitable for winter construction
The invention relates to an aluminum oxide-silicon carbide-carbonaceous cement-free castable suitable for construction in winter. The technical scheme is as follows: the castable comprises the following components in percentage by weight: 58-62wt% of dense corundum particles; 6-10 wt% of silicon carbide particles; 2-3 wt% of spherical asphalt; 4-10 wt% of alumina micro powder; 4 to 5 wt% of silicon dioxide micro powder; 7-10 wt% of silicon carbide powder; 1 to 1.5 wt% of silicon powder; 0.1-0.15 wt% of polyacrylic acid; 6-9 wt% of dense corundum fine powder; 0.04-0.1 wt% of water-soluble fibers; and 0.2-0.3 wt% of caustic-burned magnesia powder. During construction, when the environment temperature and the water temperature are both lower than 15 DEG C, after construction is completed, a pouring body is cured at 33-38 DEG C until the pouring body is completely cured. The concrete has the advantages of being small in water adding amount, short in setting time and high in construction site safety, is good in compactness, free of cement, high in thermal strength and good in various technical indexes, and particularly completely meets the requirements of construction in winter.
本发明涉及一种适用于冬季施工的氧化铝‑碳化硅‑碳质无水泥浇注料。其技术方案是：所述浇注料各组分及其含量是：致密刚玉颗粒为58～62wt％；碳化硅颗粒为6～10wt％；球状沥青为2～3wt％；氧化铝微粉为4～10wt％；二氧化硅微粉为4～5wt％；碳化硅粉为7～10wt％；硅粉为1～1.5wt％；聚丙烯酸为0.1～0.15wt％；致密刚玉细粉为6～9wt％；水溶性纤维为0.04～0.1wt％；轻烧镁粉为0.2～0.3wt％。施工时环境温度和水温均小于15℃时，施工完毕后，浇注体在33～38℃条件下养护至完全固化。本发明不仅具有加水量小、凝固时间短和施工现场安全性高的特点，且致密性好、无水泥、热态强度高和各项技术指标好，尤其是完全满足冬季施工的要求。
