High-strength light anti-explosion castable
The invention belongs to the technical field of refractory castable, and particularly relates to high-strength light anti-explosion castable. Raw materials of the explosion-proof fiber light aluminum powder concrete comprise explosion-proof fibers and light aluminum powder, and further comprise silicon carbide fine aggregate, silicon carbide powder, silicon carbide micro-powder and a strengthening binding agent group, and the strengthening binding agent group comprises calcium aluminate cement, silicon micro-powder gel and spherical asphalt. Finally, the cast brick cured by the castable has the following characteristics: 1, a solid area is compact, the whole brick is relatively light, and the corrosion resistance and the scouring resistance are outstanding; 2, main materials are all silicon carbide, so that the overall uniformity of thermal expansion performance of the cast brick is ensured, and cracks are not easy to appear in the cast brick in the use process; and 3, three different binding agents of the strengthening binding agent group respectively have binding effects with different characteristics, and finally, the pouring brick has the characteristics of high binding strength and difficulty in abrasion.
本发明属于耐火浇注料技术领域，尤其涉及一种高强度轻质防爆浇注料。本发明的原料组成包括防爆纤维，以及轻质铝粉，还包括碳化硅细骨料、碳化硅粉料、碳化硅微粉料，以及强化结合剂组，强化结合剂组为铝酸钙水泥、硅微粉凝胶，以及球状沥青，最终使得该浇注料固化后的浇注砖具有以下特点：1、实心区域致密、整体相对轻质，耐腐蚀和耐冲刷性能突出；2、主要材料全部为碳化硅，保证浇注砖具有热膨胀性能的整体均一性，使用过程中内部不易出现裂缝；3、强化结合剂组的三种不同结合剂，各自具有不同特点的结合效果，最终保证浇注砖具有结合强度大、不易磨损的特点。
