Embodiment Construction

[0019] The method of quantitatively measuring the corrosion degree of ancient bricks in a certain site is carried out according to the following steps:

[0020] (1) Take 3 bricks from the site and fully soak them in distilled water until they are saturated. Record the weight of each brick at this time, which are 13.78 g, 45.91 g, and 106.03 g respectively, and then bake them at 105°C for 8 Hour, dry it, and record the weight of each brick, respectively 10.83g, 36.09g, 83.32g

[0021] (2) Calculate the solid content G of each brick, namely:

[0022] G 1 =[P 1 ’ / (P 1 -P 1 ’)]×100%

[0023] =[10.83 / (13.78-10.83)]×100%=367.1%

[0024] G 2 =[P 2 ’ / (P 2 -P 2 ’)]×100%

[0025] =[36.09 / (45.91-36.09)]×100%=367.5%

[0026] G 3 =[P 3 ’ / (P 3 -P 3 ’)]×100%

[0027] =[83.32 / (106.03-83.32)]×100%=366.9%

[0028] Take their average value as G, that is

[0029] G=(1 / 3)×(G 1 +G 2 +G 3 )

[0030] =(1 / 3)×(367.1%+367.5%+366.9%)=367.2%

[0031] (3) Take 3 bricks that have not been corroded and have ...

Abstract

The invention discloses a method to quantitatively measure corrosion degree of an ancient brick, firstly defining solid content, reference brick and corrosion degree for the ancient brick, measuring the weights of the water saturated and dried ancient brick and reference brick respectively, calculating solid contents of the ancient brick and reference brick, subtracting the ratio of the solid content of the ancient brick to that of the reference brick from one to obtain the corrosion degree of the ancient brick. This method has the advantages: convenient and easy to operate without complex instruments and devices, by simply measuring and calculating, and it can objectively and quantitatively evaluate the corrosion degree of the ancient brick, and provides scientific basis for protecting, repairing and reasonably using ancient architectures.

Description

Technical field: [0001] The invention relates to the identification and protection of ancient building materials, and more specifically to the identification and protection of brick materials in ancient buildings. Background technique: [0002] Under certain environmental conditions, bricks in ancient buildings will always undergo different degrees of corrosion over a long period of time. The prior art can only qualitatively describe the degree of corrosion of ancient building bricks, but its disadvantage is that it lacks comparability due to the inability to quantitatively describe the degree of corrosion of ancient building bricks. Summary of the invention: [0003] The purpose of the present invention is to provide a method for quantitatively measuring the corrosion degree of ancient bricks. The method firstly defines the solid content of the bricks, the reference bricks and the corrosion degree of the bricks. After measuring the saturated bricks of the ancient bricks and the...
