Infusion and binding material composition

Abstract

The invention relates to an infusion and binding material composition containing the following components in proportion by weight: 20%-60% of natural hydraulic lime, 35%-78% of aggregates, 0-2% of polymer latex powder, 0.01%-2% of water reducers and 0.01%-2% of water-retention thickeners. 20%-50% of water is added in per 100 kg of materials mixed by the formula for uniformly stirring, and then the material composition can be used. The invention can satisfy the special requirements for infusing, binding and reinforcing brick and stone materials in historical buildings, positions infused and bound by adopting the infusion and binding material composition have similar performance to bricks and stones in the constructed positions, and the infusion and binding material composition has the advantages of environmental protection, safe solidified material, excellent binding force, good weather resistance and self-cure performance.

Description

technical field The present invention generally relates to the protection and restoration of cultural relics or historical buildings, and more specifically relates to a perfusion bonding restoration material composition for masonry cultural relics and historical buildings. Background technique Masonry cultural relics (including petroglyphs, stone or clay sculptures, inscriptions, etc.) and historical buildings are an important part of Chinese cultural heritage, but under the influence of various natural factors and human activities, they often appear aging, void, etc. Drums, peeling, breakage, breakage and missing phenomena require constant maintenance, repair and protection. In these protection projects, suitable protective materials are required for bonding fractured components, filling hollow and damaged parts, and strengthening the structure of cultural relics. In the process of repairing these historical buildings or cultural relics, the bonding and reinforcement of m...
