Description

一种利用黄土制备太古砖的方法Method for preparing Taikoo brick using loess 技术领域Technical field
本发明涉及古建筑恢复技术领域,特别涉及一种利用黄土制备太古砖的方法。The invention relates to the technical field of ancient building restoration, in particular to a method for preparing ancient bricks by using loess.
背景技术Background technique
众所周知,秦砖汉瓦为青灰色,为古建筑的主要颜色。秦朝以后小窑烧制的砖多为青灰色,我们称之为古砖。但是,在先秦时代,中华民族主要生活在黄河流域,用黄土制成土坯用于建筑,这种土黄色的土坯我们称之为太古砖。As we all know, the Qin brick Han tile is blue-gray, which is the main color of ancient buildings. After the Qin Dynasty, the bricks fired in small kilns were mostly bluish gray, which we call ancient bricks. However, in the pre-Qin era, the Chinese nation mainly lived in the Yellow River Basin, and used clay to make adobe for construction. This kind of adobe was called Taikoo brick.
随着我国对中华民族传统文化的弘扬,一些地方着手建造先秦时代的古镇,需要大量的太古砖。With China's promotion of the traditional culture of the Chinese nation, construction of ancient towns in the pre-Qin period in some places requires a large amount of Swire bricks.
黄土是一种亲水性材料,黄土制成的土坯遇水后会产生崩解,使建筑物破坏。为了解决这一问题,需要在不改变黄土本色的条件下,将黄土改性,由亲水性材料转化为憎水性材料,使太古砖能够经久耐用,以满足建造先秦古镇对建筑材料的要求。Loess is a hydrophilic material. The adobe made of loess will disintegrate when it encounters water, which will destroy the building. In order to solve this problem, the loess needs to be modified without changing the natural color of the loess, from hydrophilic materials to hydrophobic materials, so that the Swire bricks can be durable to meet the requirements of building materials for the construction of ancient towns in the pre-Qin Dynasty.
发明内容Summary of the invention
针对上述技术上存在的不足,本发明提供了一种利用黄土制备太古砖的方法,简单易行,成本低,节能环保,易于推广使用。In view of the above technical deficiencies, the present invention provides a method for preparing Taikoo bricks using loess, which is simple and easy to implement, low in cost, energy-saving and environmentally friendly, and easy to popularize and use.
