Embodiment Construction

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

[0020] (1) Take 3 bricks from the ruins, fully soak them in distilled water to saturation, record the weight of each brick at this time, which are 13.78 grams, 45.91 grams, and 106.03 grams, and then bake them at 105°C for 8 hour, dry it, and record the weight of each brick, which are 10.83 grams, 36.09 grams, and 83.32 grams

[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 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 b...

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 identification and protection of ancient building materials, and more particularly relates to material identification and protection of bricks in ancient buildings. Background technique: [0002] Bricks in ancient buildings, under the action of certain environmental conditions, will always undergo corrosion to varying degrees after a long period of time. The existing technology can only qualitatively describe the corrosion degree of ancient building bricks, and its shortcoming is that it lacks comparability because it cannot quantitatively describe the corrosion degree of ancient building bricks. Invention content: [0003] The purpose of the present invention is: provide a kind of method of quantitative measurement ancient brick corrosion degree, this method at first defines the solid content of brick, reference brick and the corrosion degree of brick, through measuring the saturated brick of ancient brick and reference bri...
