Abstract
The invention relates to a preparation method of an inorganic gelling material for reinforcing a soil-material culture relic. The preparation method includes following steps: a) mixing limestone, red clay and fly ash together with a mass percentage ratio of the mixing limestone, the red clay and the fly ash together being 60%:30%:10%; b) carrying out a calcinating process in a high-temperature calcinating furnace at 1000 DEG C for two hours; c) performing a natural cooling process to room temperature, carrying out a grinding process in a ball mill and a sieving process through a 100 meshes screen for a subsequent process; d) mixing a finely grinded gelling material with slit sieved through a 5 meshes screen with stirring uniformly, wherein mass ratio of the slit to the gelling material powder is 2:1, stirring and moistening the mixed powdery material with water for 15 minutes with a water-cement ratio being 0.20, and then covering the mixed powdery material by a plastic film for six hours. The calcinated gelling material has a porosity reaching 43% and an average compressive strength being not less than 1.90 MPa, and is basically intact when being soaked for 200 hours. Problem of durability of a reinforced soil ruin which is subjected to crack and collapse is solved and the gelling material makes a contribution to protection of the soil-material culture relic.
Description
Technical field
The present invention relates to a kind of method of firing material of construction, is a kind of preparation method of the inorganic coagulation material of reinforcing soil property historical relic specifically.
Background technology
China's soil property historical relic is widely distributed, and abundant species, as the earth construction sites such as Great Wall, beacon flint, pass, ancient city and ancient wall, painted sculptures etc.As an extremely fragile class cultural relic entity, carrying a large amount of precious historical informations, containing China's successive dynasties politics, economy, art, building, the very important image data of scientific and technological aspects, it is the sample in kind of Ancient Times in China civilization, it is the material carrier of national culture succession, there is influence and the cohesive force of national unity and cultural identity, the Tourism Resource that Ye Shi China high-quality state-owned assets and the present age are extremely precious.
Be subject to the impact of physical environment factors, the geology disease such as the earth construction sites such as Great Wall, Gucheng, beacon flint, pass produce serious weathering, crack, cave in, also there is the diseases such as ground battle hollowing, crisp alkali, cracking, big area come off in ancient wall, painted sculptures, historical relic is caused to very large destruction, some or even destructive.Protection reinforcement material for soil property historical relic must have close physics-chem characteristic and mechanical property with the ruins soil body, so just can have good compatibility, protects reinforcement material and the good combination of historical relic body.Meanwhile, protection reinforcement material calculus body must possess good weathering resistance, i.e. resistance to environment factors, as the impact on its stability such as water, humiture variation, freeze thawing, wind erosion, weathering, have the gentle hardware features of hydraulic.
Summary of the invention
