Embodiment 1

[0020] The clam shells were roasted in a roasting furnace at 1000°C for 2 hours, cooled naturally to ambient temperature after being released from the oven, and then crushed to 150 mesh to obtain hydraulic oyster ash for repairing and protecting stone cultural relics.

[0021] Mix 150-mesh hydraulic oyster ash for repairing and protecting stone cultural relics with 100-mesh quartz sand at a mass ratio of 1:1 to obtain a cementitious material.

[0022] When in use, according to the ratio of cementitious material: water mass ratio of 100:50, stir evenly to make slurry material.

Embodiment 2

[0024] The clam shells were baked in a 1060°C roaster for 2 hours, cooled naturally to ambient temperature after being released from the furnace, and then crushed to 150 mesh to obtain hydraulic oyster ash for repairing and protecting stone cultural relics. Others are the same as in Example 1.

Embodiment 3

[0026] The clam shells were roasted in a roasting furnace at 1100°C for 2 hours, cooled naturally to ambient temperature after being released from the furnace, and then crushed to 150 mesh to obtain hydraulic oyster ash for repairing and protecting stone cultural relics. Others are the same as in Example 1.

Abstract

The invention relates to a material for reinforcing and repairing stone ruins, and in particular to hydraulic oyster ash for repairing and protecting stone ruins. The hydraulic oyster ash for repairing and protecting stone ruins is obtained by roasting clam shells in a roasting furnace at 1000-1100 DEG C, discharging, then naturally cooling to an environmental temperature, and then crushing to 150 meshes. The hydraulic oyster ash for repairing and protecting stone ruins disclosed by the invention is mainly used for a cementing material for repairing brick stone ruins; the cementing material is obtained by uniformly mixing 150-mesh hydraulic oyster ash for repairing and protecting stone ruins with 100-mesh quartz sand in a mass ratio of 1:1; during use, a slurry material is prepared by uniformly proportioning and stirring the cementing material with water in a mass ratio of 100:50. The chemical composition, mineral constituents and physical mechanical properties of the hydraulic oyster ash for repairing and protecting stone ruins disclosed by the invention are basically similar to those of hydraulic lime NHL-2 for repairing stone ruins, which is introduced in the field of historical relics of China from Germany in recent years, can be used for solving the problems of strength, durability and weather resistance of the reinforced brick stone ruins, and a novel material which is firmly combined with brick stone is provided for repairing damaged brick stone relics.

Description

technical field [0001] The invention relates to a material for strengthening and repairing stone relics, in particular to hydraulic oyster ash for repairing and protecting stone relics. Background technique [0002] my country's masonry cultural relics are widely distributed and rich in types, such as the Great Wall, tombs, grottoes, petroglyphs, stone carvings, bricks, etc. As an extremely fragile type of cultural relic entity, it carries a large amount of precious historical information, and contains extremely important image materials in the past dynasties of politics, economy, art, architecture, technology, etc. It is a physical specimen of ancient Chinese civilization and a national cultural heritage. It has the appeal and cohesion of national unity and cultural identity, and it is also a high-quality state-owned asset in my country and an extremely precious cultural tourism resource in the contemporary era. [0003] Affected by many factors in the natural environment, ...
