Abstract

涉及一种可渗透的建筑组合物，可用于维修以延长混凝土、钢筋混凝土和砖石结构的工作寿命，其包含水泥、砂、增塑剂、防锈剂、硝酸钙颗粒、双重造粒过磷酸钙、硝酸钠、浓缩无氯钾肥、苏打灰和工业氯化钙。该组合物具有良好的性能，可用于制造具有高电阻、耐水性和耐久性的固体产品。

Description

可渗透的建筑用组合物 技术领域
本发明涉及一种建筑材料，用于设置为多孔矿物基质上的防水、防冻和耐磨涂层，以恢复建筑结构的使用寿命。
背景技术
国内外已知的高效复合水泥推荐用于老旧混凝土和加工混凝土维护的“调整”和“处理”。在这样的组合物中，一般含有水泥、砂和活性组分，并含有聚合物添加剂，限于不低于5℃的使用温度。
本质上最接近的本发明方案的已知组合物包含波特兰水泥、硅砂和反应部分。这种设置可获得高轻度、防水、抗冻的具有短凝结时间的保护层，对老旧混凝土良好的粘结性和对腐蚀介质的高耐性。
上述已知组合物的缺点是由于其含有纯化合物形式的添加剂的事实，在其生产中附加的额外限制使该方案并不是很有竞争力。
发明内容
本发明的目的在于通过无机肥料替换纯化合物而改变所述组合物，并降低成本。
本发明的技术问题通过在反应部分中除了砂和水泥外引入附加化合物(化学活性部分)来解决：硝酸钙颗粒、双造粒过磷酸钙、硝酸钠、浓缩无氯钾肥、苏打灰和工业氯化钙、塑化剂和防锈剂，按以下组分的重量％计：硝酸钙颗粒0.5-0.95、双造粒过磷酸钙0.03-0.15、硝酸钠0.16-0.5、浓缩无氯钾肥0.05-0.3、苏打灰0.19-0.6、工业氯化钙0.05-0.3、塑化剂为0.01-0.1、防锈剂为0.01-0.1、 水泥为25-40、和砂为74-57。组合物各组分的定量偏差不妨碍解决所述问题。
该组合物的化学活性部分、以及常规对照样品具有多官能效应并在水合混合物中积极影响所述组合物的结构。由于本发明的固化剂是形成增长数量的初始的水泥来实现的组合物，这是形成进一步的结晶中心的先决条件，由此进一步加强在硬化初期强化框架。此外，通过高度表面张力膜加入的增塑剂组合物，有利于粘结剂颗粒的分散，继而导致熟料矿物与水和溶解的化学活性部分组分的接触区域的扩大，并因此加快水泥水化产物的胶体粒子的凝聚，加速硬化过程和快速凝聚强度。引入化学活性部分的防锈剂和缓蚀剂(双造粒过磷酸钙)以修复受到钢筋腐蚀、未在金属表面上附加的处理的结构。化学活性部分的其他组分提升技术方案的离子强度，以加快水泥水化过程。
除了防护功能，本发明要求保护的组合物可用于制造管、段、块、砖等形式的人造固体产品，在需要提升耐水性和抗冻性的情况下使用。
具体实施方式
以下实施例仅用于阐述本发明，而本发明的保护范围并非仅仅局限于以下实施例。所述技术领域的普通技术人员依据本发明的公开内容，均可实现本发明的目的。
用于测试本发明要求保护的组合物的样品以以下方式制备。在干状态下混合水泥、砂和化学活性添加剂，随后加入水(水与固体的比率为0.18)。由于本发明要求保护的设置具有多功能作用，用于物理和机械测试的样品制成两种类型：所述组合物单独样品的形式和在混凝土基层(15)上的相同组合物的保护层形式。类似地，制备样品和用于对比结果的对照样品。硬化的样品在带有水闸的腔室中以T＝20±2℃和100％湿度保持28天。在混凝土样品上实施的所述材料组合物以不超过3-5mm层的灌注方法标记为耐水性W2。保护层组合物的硬化在与对比样品相同的条件下实施。
表1中示出所述组合物渗透作用实例。本发明要求保护的组合物(表2)并未产生用于物理和机械特性的对照样品。本发明要求保护的组合物的优点是其成本较对照样品低三倍，由此更具竞争力。
