Cementing material, historic building repair mortar and preparation method of historic building repair mortar
The invention relates to the technical field of building materials, in particular to a cementing material, historic building repair mortar prepared from the cementing material and a preparation method of the historic building repair mortar, the historic building repair mortar is composed of the cementing material, aggregate, an additive and water, and the cementing material comprises the following components in parts by weight: 20-150 parts of slag and 250-500 parts of active iron tailings; a preparation method of the active iron tailings comprises the steps that iron tailings are dried and then subjected to first-time grinding, quicklime powder and water are added for second-time grinding, then high-temperature activation is conducted at the temperature of 700-800 DEG C, and the active iron tailings are obtained. According to the preparation method of the historic building repair mortar, provided by the invention, the active iron tailings and the slag are used for preparing the gel material for the historic building repair mortar, so that the bonding performance and the compressive strength of each age of the historic building repair mortar can be improved; the early strength is high, the cohesiveness is good, the erosion resistance is strong, and the durability is good.
本发明涉及建筑材料技术领域，尤其涉及一种胶凝材料，以及使用该凝胶材料制成的古建筑修复砂浆及其制备方法，该古建筑修复砂浆由胶凝材料与骨料、外加剂和水组成，所述凝胶材料包括如下重量份数的组分：矿渣20～150份和活性铁尾砂250～500份；其中，所述活性铁尾砂的制备方法为：将铁尾砂烘干后进行第一次粉磨，加入生石灰粉和水进行第二次粉磨，然后于700～800℃高温活化得所述活性铁尾砂。本发明提供的古建筑修复砂浆的制备方法通过使用活性铁尾砂和矿渣制备用于古建筑修复砂浆的凝胶材料，可以提高古建筑修复砂浆的粘结性能和各龄期抗压强度，通过本申请的制备方法得到的古建筑修复砂浆的浆体稳定，早期强度高、粘结性好，抗侵蚀强，耐久性好。
