Description

一种速凝剂及其制备方法
技术领域
本发明属于建筑辅助材料技术领域，具体涉及一种速凝剂及其制备方法。
背景技术
速凝剂是加入水泥混凝土中能促进水泥迅速凝结硬化的一种化学添加剂，主要用于对水泥混凝土有速凝要求的场合，如矿井巷道的锚喷支护、薄壁结构、曲向结构、抢险堵漏、紧急修补、矿山竖井、隧道等地下防护工程，其中用于配置锚喷支护的喷射混凝土是速凝剂的主要用途之一。目前速凝剂的主要原料为碱性物质Na2CO3，如速凝剂的典型配方是40%的碳酸钠、40%的铝酸钠和20%的生石灰，该配方虽能满足水泥混凝土速凝的要求，但是该类型的配方：含碱量大，导致混凝土的28天抗压强度下降30-50%，有碱骨料反应破坏的危险，且产生严重的化学污染；吸水性较大，施工后需及时洒水加强养护；干缩率大、抗渗性差、回弹大、材料损失多；对施工人员的皮肤、眼睛产生强烈的刺激腐蚀作用。因此含碱量低又能满足水泥混凝土速凝要求的速凝剂才是市场所需要的。
脱硫石膏渣是电厂的固体废渣，产量非常大，且严重污染环境，因此研究如何二次利用脱硫石膏渣成为电厂发展的瓶颈，也是社会亟待解决的问题。
发明内容
本发明的目的是针对目前速凝剂存在的含碱量高、干缩率大、抗渗性差、回弹大、材料损失多和对工作人员伤害大的技术缺陷，提供一种含碱量低、绿色环保安全的速凝剂及其制备方法。
本发明为解决上述技术问题而采用的技术方案是：
一种速凝剂，其特征在于：它是由下列重量份数的原料组成的：石灰石10～30份、铝矾土18～36份、脱硫石膏渣3～5份、粉煤灰 25～50份、高效减水剂6～15份、激发剂0.05～0.1份。
上述的速凝剂，其特征在于：所述的原料及重量份数为：石灰石20份、铝矾土25份、脱硫石膏渣4份、粉煤灰 35份、高效减水剂10份、激发剂0.075份。
上述的速凝剂，其特征在于：所述高效减水剂为萘磺系高效减水剂，激发剂为十二烷基硫酸钠和甲基纤维素按重量配比1:1混合而成。
上述速凝剂的制备方法，其特征在于：它包括以下步骤：将各种原料烘干，再将石灰石、铝矾土、粉煤灰按照原料配比份数混合，在1000℃—1100℃下进行烧结，再将烧结料与脱硫石膏渣、激发剂按照原料配比份数混合，磨至勃氏比表面积为400-500m2/kg。
与现有技术相比，本发明具有以下有益效果：
1、本发明采用的原料是工业废渣，掺该速凝剂后水泥水化产物中C-S-H凝胶及钙矾石的量较多，水泥石的孔分布较均匀，因此后期强度不但不下降，相反还有一定程度的提高。
2、本发明利用火电厂的脱硫石膏废渣和铝质原料，按照适当的配比经煅烧后磨细，再加入高效减水剂和激发剂配制而成，它与水拌合后，1-5分钟内即迅速生成钙矾石从而在水泥浆中形成网状结构导致速凝，而在后期由于高效减水剂的作用弥补了水泥快凝导致的后期强度低的缺陷，有利于提高混凝土后期强度，由于激发剂的作用提高了混凝土的粘结性和和易性，降低了回弹率，减少了粉尘量，同时提高了混凝土的密实性，使之具有良好的抗渗和抗冻性能。
3、本发明对钢筋无锈蚀作用，对施工人员的皮肤、眼睛无伤害。
4、利用本发明施工简便易行，可以不用模板或只用单面模板，省去了支模浇注和拆模工序，节约了大量的模板材料和制模时间；使砼的输送、浇注和捣固合为一道工序，无需专门的运输和振捣设备，加快了衬砌施工速度；喷射的砼密实度高，强度和抗渗性能较好，可以节约砼；可通过输料软管，在高空或狭小的工作区间向任意方向施作薄壁结构，工作简单、机动、灵活、有着广泛的适应性，衬砌总成本约可降低30%。
5、本发明利用脱硫石膏渣生产速凝剂，既实现了脱硫石膏渣的二次利用，节约了资源，又解决了电厂固体废渣的处理问题，保护了环境。
