Abstract

本发明公开了一种耐火混凝土，包括以下重量份的各成分：30‑45份的亚铝酸盐水泥，17‑23份的废砖，11‑15份的铝矾土熟料，17‑23份的铝酸盐水泥，15‑20份的加强纤维，11‑12份的骨料，9‑16份的硅灰，6‑9份的密胺系减水剂和50‑80份的水。混凝土通过加强纤维在其中杂乱无章分布，协助混凝土承担拉应力和传递拉应力，阻止宏观裂缝的扩展，从而提高混凝土抗折强度和韧性；通过骨料和硅灰的加入可以增加混凝土的强度，降低泥土对混凝土的影响，密胺系减水剂能减少水的用量，混凝土耐火效果优异，热稳定性好，废砖来源广泛，价格低廉，节约资源。

Description

一种耐火混凝土
技术领域
本发明涉及一种混凝土，尤其涉及一种耐火混凝土。
背景技术
混凝土是指由胶凝材料将集料胶结成整体的工程复合材料的统称。随着目前我国房地产行业的快速发展，对于混凝土的需求量也越来越大，同时对于混凝土的各种性能也越来越重视，耐火混凝土由此产生，目前市场上所销售的耐火混凝土耐火效果差，混泥土的强度小，易开裂。因此，本发明提出了一种新的技术方案。
发明内容
为解决上述问题，本发明提供一种耐火混凝土，强度大，不易开裂。
一种耐火混凝土，包括以下重量份的各成分：30-45份的亚铝酸盐水泥，17-23份的废砖，11-15份的铝矾土熟料，17-23份的铝酸盐水泥，15-20份的加强纤维，11-12份的骨料，9-16份的硅灰，6-9份的密胺系减水剂和50-80份的水。
所述亚铝酸盐水泥的原料为铝矾土和石灰石，将铝矾土与石灰石按照1：1的比例煅烧成熟料，将熟料磨制而得亚铝酸盐水泥。
进一步的，一种耐火混凝土包括以下重量份的各成分：38份的亚铝酸盐水泥，20份的废砖，13份的铝矾土熟料，20份的铝酸盐水泥，18份的加强纤维，11份的骨料，13份的硅灰，8份的密胺系减水剂和65份的水。
本发明的有益效果：混凝土通过加强纤维在其中杂乱无章分布，协助混凝土承担拉应力和传递拉应力,阻止宏观裂缝的扩展,从而提高混凝土抗折强度和韧性；通过骨料和硅灰的加入可以增加混凝土的强度，降低泥土对混凝土的影响，密胺系减水剂能减少水的用量,混凝土耐火效果优异，热稳定性好，废砖来源广泛，价格低廉，节约资源。
