Method and device for detecting reinforcement effect of stone and stone relic reinforcing agent

Abstract

Relating to the field of stone and stone relic protection, the invention provides a preparation method of a deteriorated rock imitation as well as a method and device for detecting the effect of a stone or stone relic reinforcing agent with the imitation. According to the method of the invention, powdered calcium carbonate and granular calcium carbonate are adopted as the raw materials and are fully mixed with water, and then the mixture is placed in a designed device. Through impact compaction by a hammer of certain quality, the imitation of deteriorated stone can be obtained. The deteriorated stone imitation is reinforced by means of spraying, brushing or direct mixing of the reinforcing agent and other methods, and its compressive strength or surface strength is measured, thus visually and quantitatively representing the reinforcement effect of the reinforcing agent. In order to implement the above method, the invention also provides a detection device. The method of the invention has the advantages of: (1) easily available raw materials; (2) low price; (3) simple operation; (4) visual result; and (5) wide application.

Description

technical field [0001] The invention relates to the field of protection of stone and stone cultural relics, and provides a method for preparing a degraded rock imitation and a method and a device for detecting the effect of a stone or stone cultural relic reinforcing agent using the imitation. Background technique [0002] Large-scale stone carvings, stone carvings, monuments and other stone components, as well as numerous stone monuments, are important cultural heritages of the country and nation, with high historical, artistic and scientific value, but most of them are exposed to the weathering environment of nature , because they are mainly composed of minerals with low erosion resistance, weathering and corrosion are serious. If no effective protection measures are taken for them, the cultural information they carry will disappear. Although the most fundamental measure is to control the external environment, it is impossible to completely remove the influencing factors ...

AI Technical Summary

Problems solved by technology

These protective materials can be divided into surface protection and reinforcement materials according to their functional effects. The surface protection effect can be directly characterized by indicators such as acid resistance, stain resistance, and hydrophobicity, which is very convenient for investigation. Freeze-thaw resistance test or salt crystallization resistance test to characterize, but the test cycle is long, and it is not easy to get results quickly; and after reinforcement, the direct change of stone strength is also difficult to measure, even if it is expressed by testing the mechanical strength of the sample, because The strength of the stone itself is high, so the measurement error is large
