Description

钢渣水泥改性增强剂
技术领域
本发明涉及一种水泥化学领域的水泥增强剂，具体涉及一种用于水泥生产过程中添加的钢渣水泥改性增强剂。
背景技术
在以钢渣为原料进行水泥生产的过程中，受钢渣的活性差等因素的制约，传统的钢渣水泥增强技术，一般是采用添加3％到10％，甚至10％以上的大量活性激发剂的办法。这种办法生产的水泥，成本高、副作用大，水化率及有效利用率低、凝结时间长、早期强度低，不能满足正常施工的要求，不能够大量使用。为此，特进行如下发明。
发明内容
本发明所要解决的技术问题是：激发钢渣水泥的活性、改善其综合性能、提高水化率及有效利用率。其核心是提供一种由硫酸铝钾、硫酸铝铵、偏硅酸钠、硫酸亚铁、三聚氰胺树脂等组成的钢渣水泥改性增强剂，适应以钢渣为原料进行高效增强水泥生产的需要。
为解决上述问题，本发明的技术方案是：把硫酸铝钾、硫酸铝铵、偏硅酸钠、硫酸亚铁、三聚氰胺树脂等改性增强物质以一定的比例、一定的程序进行科学配比，充分发挥各类物质的有效特性，形成一种适应以钢渣为原料进行水泥生产的钢渣水泥改性增强剂。在水泥粉磨过程中，加入本发明的钢渣水泥改性增强剂，使生产出的高效增强水泥在实际的应用中，其前期的水化过程能够适时、足量地生成钙矾石、水化硅酸钙、硬硅钙石、白钙沸石、杆沸石、钠沸石、方沸石、水化硫铁酸钙、水化硫铝酸钙等交互相连的骨架结构，在此后的各龄期中，这种交互相连的骨架结构能够持续增强并满足实际应用中的综合要求。
本发明的特点是：添加本发明的钢渣水泥改性增强剂生产的钢渣水泥，在水泥的应用实践中，前期形成的骨架结构所体现的强度及凝结时间等性能，均能达到或超过同等级的通用硅酸盐水泥的性能；二次反应及持续水化形成的贯穿相连的多中心物质，能使钙盐结构不断密实、增强。
早期强度高、凝结时间适中是本发明的另一特点。用本发明的钢渣水泥改性增强剂生产的钢渣水泥，在水泥石及配制的混凝土的和易性、密实性、耐久性、抗渗性、抗缩性、抗蚀性、抗冻融性、抗炭化性等性能方面，均优于同等级通用硅酸盐水泥的性能。
其有益效果是：本发明的钢渣水泥改性增强剂，在生产过程中的只需掺入占水泥生产原材料总量的1％，其性能--价格比低、低碱、无氯、无害、无毒副作用。
通过调整本发明的钢渣水泥改性增强剂的配方比例，能够广泛适用于各类钢渣水泥、矿渣硅酸盐水泥、复合硅酸盐水泥、粉煤灰硅酸盐水泥、火山灰硅酸盐水泥、普通硅酸盐水泥及其它种类的硅酸盐水泥等的生产，掺量仅为水泥生产原材料的1％，能够从根本上激发各类水泥的活性、改善其综合性能、提高水化率及有效利用率，使凝结时间缩短、各龄期强度增强、可满足各种施工条件的要求、综合性能达到或超过通用硅酸盐水泥。
具体实施方式
下面对本发明的使用机理、实施方式做进一步详细的说明。本发明是由具有改性、增强功能的多组分激发改性物质组成，针对钢渣水泥中的原材料--钢渣的化学成分进行充分的化学反应，重点解决水泥应用中的早期凝结时间、强度、以及各龄期的增强改性问题。在钢渣水泥的生产过程中，只需掺入占水泥生产原材料总量的1％的本发明，就能生产出符合要求的高效增强水泥。在这种钢渣水泥的应用早期，通过加速水化、二次反应、消解f-cao等，生成足量的钙矾石、水化硅酸盐、水化硫铁酸钙等，使凝结时间缩短、强度增强，满足各类施工的要求；在水泥应用后，各龄期持续水化，生成相互交织生长的多种钙复盐，混凝土的强度得到增强、密实性增加，综合提高钢渣水泥应用中的各种性能。
