Embodiment Construction

[0014] First, use hot air at 50°C to 80°C for 20 to 30 minutes for the cured concrete samples of cultural relics in the field or in the laboratory to evaporate the water.

[0015] Second, for the cultural relic concrete samples on site, the surface needs to be polished with sandpaper. For laboratory samples, it should be ground to a standard powder.

[0016] Third, use XRF (desktop or portable) equipment or infrared spectrometer to analyze the mineral components of the cured material of cultural relics, and detect CaO, SiO 2 , Al 2 O 3 , Fe 2 O 3 , SO 3 , TiO 2 equal mineral content.

[0017] Fourth, calculate the eigenvalues ​​of mineral component content of cultural relic concrete material samples, including CaO / SiO 2 , CaO / Al 2 O 3 , CaO / Fe 2 O 3 , Al 2 O 3 / Fe 2 O 3 , SiO 2 / Al 2 O 3 , SiO 2 / Fe 2 O 3 , CaO / SO 3 , SiO 2 / SO 3 , CaO / TiO 2 Wait.

[0018] Fifth, according to the age when the cultural relic concrete material samples were produced, in...

Abstract

The invention discloses a reduction method for making a formula of cultural relic building concrete material. By calculating the characteristic value of the mineral component content of the cultural relic building concrete material sample, including CaO / SiO2, CaO / Al2O3, CaO / Fe2O3, Al2O3 / Fe2O3, etc., the The characteristic value of the mineral component content of the sample is compared with the characteristic value of the mineral component content of the reference formula, and the production formula of the cultural relic building concrete material sample is analyzed. The invention can solve the technical problem of formula restoration of highly carbonized building concrete materials, including the technical problem of formula restoration of cultural relic building concrete materials and modern building concrete materials; it can directly restore the cultural relic building site on the basis of not damaging the cultural relic building The formula analysis of concrete materials is carried out to realize the non-destructive archaeology and formula research of the concrete material technology of cultural relics. At the same time, this method can become an auxiliary method for the study of the chemical composition of modern concrete materials.

Description

technical field [0001] This technology is used in the archaeology of cultural relics and building materials, and is used to analyze the production formula of the cured material of cultural relics building concrete materials (or cementitious materials), and it is also suitable for the restoration of the production formula of modern building concrete. Background technique [0002] The problem of restoration of the production formula of cultural heritage building concrete materials, especially the restoration of the production formula of highly carbonized building concrete materials, has always been an unsolved problem. [0003] The technology similar to the present invention is the analysis and determination method of chemical composition of building cementitious material (the cementitious material is the main component of concrete material.) and the use method of related equipment. Existing analytical methods use chemical analysis and spectral analysis methods to analyze the ...
