Embodiment 1
[0063] This embodiment is a kind of anti-weathering reinforcing agent for loess relics and its preparation and reinforcement method. The test site is the non-relic area of Hanguangmen Relics Museum of Tanghuang City Wall in Xi'an City, Shaanxi Province.
[0064] The anti-weather reinforcement material for the loess ruins used in this example contains two types of reinforcements, CB-I and CB-II, among which the reinforcement agent CB-I is an anhydrous solution that dissolves 5 grams of oxalic acid and 1 milliliter of phosphoric acid in every 1000 milliliters of ethanol. Color clear solution; No. CB-Ⅱ reinforcement is a colorless and clear solution that dissolves 15 grams of barium hydroxide in every 2500 milliliters of methanol. The chemical raw materials are all industrial pure.
[0065] When preparing the above-mentioned anti-weather reinforcement agent for loess relics, the following steps are included:
[0066] Step 1: Preparation of No. CB-I reinforcing agent: Dissolve ...
