Embodiment 1

[0025]The invention provides a concrete formula system for repairing cultural relic buildings and a method for using the same. The concrete formula system is composed of a solid phase and a water phase; the solid phase and the water phase are in the range of 1:0.5- 2. Mixing; the solid phase composition is: 27wt%-95wt% of gel matrix, 2wt%-40wt% of active silicon dioxide, and 2wt%-30wt% of active calcium oxide.

[0026] The specific usage method includes the following steps:

[0027] Step 1: Sampling on site to prepare concrete samples for cultural relic buildings;

[0028] Step 2: Use XRF spectrometer and Raman spectrometer to detect the chemical composition and content of cultural relic building concrete samples: make melting and pressing sheets of cultural relic building concrete samples; use XRF spectrometer and Raman spectrometer to perform standard operations to detect the content of cultural relic building concrete samples Melting and pressing, it is detected that the c...

Embodiment 2

[0041] The invention provides a concrete formula system for repairing cultural relics buildings and its use method, and the specific use method includes the following steps:

[0042] Step 1: Sampling on site to prepare concrete samples for cultural relic buildings;

[0043] Step 2: Use XRF spectrometer and Raman spectrometer to detect the chemical composition and content of cultural relic building concrete samples: make melting and pressing sheets of cultural relic building concrete samples; use XRF spectrometer and Raman spectrometer to perform standard operations to detect the content of cultural relic building concrete samples Melting and pressing, it is detected that the cultural relic concrete contains calcium silicate and calcium sulfate; the regression analysis method is used to obtain 40wt% of calcium silicate and 64wt% of calcium sulfate.

[0044] Step 3: Use the titration method to detect the mass percentage of the chemical components magnesium oxide, aluminum oxide,...

Abstract

The invention discloses a concrete formula system for repairing cultural relic buildings and a use method thereof. The method includes: acquiring a first index value, a second index value and a thirdindex value of a cultural relic building concrete sample, and performing comparison with a first index value, a second index value and a third index value in a database of the concrete formula system,and acquiring the raw material components and content of an original cultural relic concrete making formula to prepare a repaired concrete sample; detecting a first index value, a second index valueand a third index value of the repaired concrete sample and performing comparison with the first index value, the second index value and the third index value of the cultural relic building concrete sample; if the result is that the difference of the first index value is not greater than 20%, the difference of the second index value is not greater than 60%, and the difference of the third index value is not greater than 60%, using the repaired concrete sample to repair the cultural relics. The system and method provided by the invention realize reduction of the cultural relic building concretematerial formula, and reach the purposes of repairing according to raw materials and original process and maintaining cultural importance.

Description

technical field [0001] The invention relates to the technical field of restoration of cultural relics, in particular to a concrete formula system for repairing cultural relics buildings and its application method. Background technique [0002] The restoration of cultural relic buildings generally requires repairing according to "raw materials and original craftsmanship" and maintaining "cultural importance", and the original old materials of cultural relic buildings should be used as much as possible. The concrete material of cultural relic buildings is a building material made of multi-formulation and multi-raw materials after mixing, calcining, and compounding. It generally contains mortar or stucco. It is difficult to find old materials. Therefore, for cultural relic buildings of concrete materials, in When repairing, repair materials that are closer to the workability, durability, mechanical properties, and chemical properties of the old materials should be used as much ...
