Embodiment Construction

[0026] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0027] The main solution of the embodiment of the present invention is: the lime mortar is prepared from hydraulic lime, blast furnace slag, aluminate cement, aggregate, additives and water, and the hydraulic lime mortar is used as a dry-hanging masonry wall joint filling material, Improve the elastic properties and durability of materials, and reduce the resource and environmental problems caused by blast furnace slag to a certain extent. Specifically, S75 grade granulated blast furnace slag can be stimulated by natural hydraulic lime, which has hydraulic gel properties, accelerates the development of early strength of mortar, refines the internal void structure of mortar, improves the strength of mortar, and reduces the natural water volume of the same volume. The amount of hard lime reduces environmental poll...

Abstract

The invention discloses lime mortar for dry-hanging masonry wall joint filling and a preparation method thereof.The lime mortar is prepared from hydraulic lime, blast furnace slag, aluminate cement, aggregate, an additive and water, the hydraulic lime mortar serves as a dry-hanging masonry wall joint filling material, the elastic property and durability of the material are improved, and the dry-hanging masonry wall joint filling material is suitable for being used as a dry-hanging masonry wall joint filling material. The resource and environment problems caused by the blast furnace slag are alleviated to a certain extent; the expanded aluminate cement is slightly expanded in volume and is adaptive to structural deformation, and the additive improves the breaking strength and compressive strength of the mortar, so that the mortar can better play a role in caulking.

Description

technical field [0001] The invention relates to the technical field of dry-hanging masonry walls, in particular to a lime mortar used for caulking dry-hanging masonry walls and a preparation method thereof. Background technique [0002] At present, the dry-hanging masonry walls are mostly made of weather-resistant adhesive and cement-based mortar as joint filling materials. The weather-resistant adhesive is elastic, so that the dry-hanging masonry and the main structure can be deformed cooperatively. It is mostly used in stone curtain walls and ceramic board curtain walls; As a caulking material for the wet sticking process of wall tiles. However, the weathering adhesive has low durability and low moisture permeability, and large-scale use will increase the cost and affect the performance of the wall. The high strength of cement-based mortar is easy to cause damage to the masonry body, and it deteriorates in water and has poor water permeability, resulting in the problem of...
