Abstract

The invention relates to a loess relic efflorescence-proof reinforcing agent and a preparation and reinforcing method thereof. The method comprises the following steps: dissolving 5-25g of oxalate and 1-15ml of CB-I reinforcing agent prepared from phosphoric acid in every 1000ml of ethanol, and dissolving 15-150g of CB-II reingorcing agent prepared from barium hydroxide in every 2500ml of carbinol; and utilizing a dual reinforcing method of carrying out microprecipitation and adsorption on the losess relic by the CB-I reingorcing agent and the CB-II reingorcing agent, and utilizing a three-step dripping mode to achieve the reinforcing effect. By adopting the technical scheme of the invention, a loess relic efflorescence-proof reinforcing material and the reinforcing method which are suitable for dry, semi-dry and humid environment conditions of a semihumid area are obtained. The chemical raw materials of the invention are technical pure, and has the advantages of low cost, simple manufacturing process and reinforcing method, and easy operation, thereby having good market development prospect. After being processed by the loess relic efflorescence-proof reinforcing material of the invention according to the reinforcing method, the loess relic shows excellent reinforced effect.

Description

technical field

[0001] The invention relates to the technical field of cultural relics protection materials, in particular to a reinforcement material for protecting loess relics. Background technique

[0002] Earthen ruins are traces of production and life in a specific period left by ancestors, carrying important historical and cultural information, and are of great value to ancient culture research; however, the particularity of soil pan-alkali, weathering, water erosion and biological reproduction caused Huge difficulties in the protection of earthen sites. At present, the diseases of earthen sites are mainly affected by their own composition, structure and environmental factors, which make it difficult for the soil to maintain water balance, and eventually lead to a decrease in bearing capacity after excessive water absorption or desertification of soil due to excessive water loss. Therefore, the development of anti-weathering reinforcement protection materials and rei...
