Description

特种高强度水泥
本发明涉及一种建筑结构型材料，尤其是一种特种高强度水泥。
长期以来，建筑使用的水泥为第二族元素化合物的胶凝材料，这种普通硅酸盐水泥石中存在高碱性水化物，即游离氧化钙，安全性差，易龟裂，凝结时间长，施工周期长且标号低。而现用于防水的材料大部分为有机防水材料，它们易老化、耐久性能差，因而抗渗性能差。
本发明目的在于提供一种早强、高强、高抗渗、高抗冻、抗腐蚀、高耐久性，广泛节约能源、充分利用废料的特种高强度水泥。
本发明包括水淬矿渣和灰渣组分(A)、激发剂组分(B)和无机氧化剂缓凝剂组分(C)。组分(A)包括水淬矿渣和粉煤灰、炉渣，水渣根据化学成分含量，三个参数及值域为：
Figure A9711422800031
Figure A9711422800032
Figure A9711422800033
组分(A)中的粉煤灰的含C量＜10％，其余水淬矿渣TiO2和Fe2O3＜3％。组分(B)的主要成分为激发剂Na2SiO2，调整Na2SiO2的模数为M=1～1.5。组分(c)用无机氧化物作缓凝剂，常用量1～3％，根据含量可以调整凝结时间。各组分的百分率如下：
组分(A)为90％以上；
组分(B)为7～8％；
组分(c)为1～3％。
以下用实施例详细说明本发明。
本发明包括水淬矿渣和灰渣组分(A)、激发剂组分(B)和无机氧化物缓凝剂组分(c)。组分(A)包括高炉水淬矿渣和粉煤灰、炉渣，水渣根据化学成份含量，三个参数及值域为：碱性参数Mo≥1.0；活性参数Ma≥0.3；质量参数Mk＞1.65，组分(A)中的粉煤灰的含C量＜10％，其余水淬矿渣Fe2O3＜3％、TiO2＜4％。组分(B)主要成份为激发剂Na2SiO2。组分(A)的高炉水淬矿渣内潜有活性物质，在激发剂Na2SiO2的激发作用下，矿渣分子解体，其共价健和离子健断裂，化学分子重新组合，形成石榴石、方沸石、钠沸石之类的人造石头，结构十分致密，孔隙率低，与集料粘结牢固。本发明组分(c)为无机氧化物的缓凝剂，根据质量要求调整模数，且根据组分(c)的掺量可控制初凝时间。
本发明采用高效复合激发剂激发矿渣中活性物质，化学分子重新组合形成石溜石、方沸石、纳沸石之类的人造石头，结构致密、孔隙率低、高强度、高抗渗。试验表明：一天强度可达30-70MPa，二十八天可达90～110MPa；抗渗试验在4MPa、恒压6小时条件下，渗水深度1～5mm之间；抗冻性能800-1000次循环；水化热140焦/克；耐磨性0.37kg/m2；与钢筋粘结力3.9-6.2MPa；混凝土弹性模量(3.18～4.01)×104MPa；混凝土化学腐蚀在10％ MgSO4溶液中浸泡30天强度还有所增加；混凝土抗折强度4-8MPa；混凝土吸水率4.56～2.20％。综上所述，本发明是一种早强、高强、高抗渗、高抗冻、抗腐蚀、高耐久性，且成本低的水泥，适用于防水工程，公路修补及特殊工程、地下渗水和海底隧道工程、军事工程、固化有毒物质等项目。
