Description

一种修缮文物建筑的混凝土配方体系及其使用方法 技术领域
本发明涉及文物修复技术领域，尤其涉及一种修缮文物建筑的混凝土配方体系及其使用方法。
背景技术
文物建筑的修缮一般要求按“原材料、原工艺”修缮以及保持“文化重要性”，尽可能采用文物建筑原来的老旧材料。文物建筑的混凝土材料，是一种多配方、多原材料经过混合、煅烧、化合而成的建筑材料，一般包含砂浆或灰泥，很难找到老旧材料，因此对于混凝土材料类的文物建筑，在修缮时应尽可能采用与老旧材料的和易性、耐久性、力学性能、化学性能等较接近的修缮材料，以还原老旧材料的配方。现有技术中，混凝土材料类的修缮材料在配制时，一般会考虑修缮材料的抗压强度、凝结时间及抗干缩性的问题，但对于混凝土材料的老旧材料还原程度较低，难以达到按“原材料、原工艺”修缮以及保持“文化重要性”的目的。
申请号为201810267192.0，名称为：一种用于修复近代文物建筑装饰的泥灰，公开了包括水、粉煤灰、生石灰、水洗中砂、活性二氧化硅、活性而氧化钙、硅酸、碳酸氢钙和氧化钛的泥灰配方，该配方主要针对含水洗中砂量较多的一类泥灰，而对于含粉煤灰量较多或生石灰量较多的泥灰，则无法进行配制，从而限制该配方的使用。
另一方面，现有技术中对于老旧材料的还原程度较低，一般只是通过一些光谱检测分析或化学分析方法测定出老旧材料中各个化合物成分的含量，采用现有材料进行混合配制，然而，随着时间的推移，同样种类或名称的原材料与现有材料区别较大，例如，以前的水泥熟料与现有的水泥熟料，由于制作工艺不同，导致生产出来的水泥熟料物理性质、化学性质存在一定区别，从而采用现有材料中的水泥熟料无法正真还原为老旧材料中的水泥熟料，因此，仅仅测出老旧材料中各个化合物成分的含量，无法做到老旧材料的还原，从而无法达到按“原材料、原工艺”修缮以及保持“文化重要性”的文物保护目的。
因此，现有技术存在缺陷，需要改进。
发明内容
本发明的目的是克服现有技术的不足，提供一种修缮文物建筑的混凝土配方体系及其使用方法，解决现有技术，无法配制含硅酸盐较多或碳酸盐较多或氢氧化物较多或粉煤灰量较多或生石灰量较多的泥灰(或混凝土)的问题；同时解决无法还原老旧材料的原材料配方，导致无法达到“原材料、原工艺”修复以及保持“文化重要性”的文物保护目的的问题。
