Abstract

The present application relates to a slow-release building mortar and a preparation method thereof, which are mainly prepared from the following components in the following proportions by weight: The disadvantage of performance is mainly through the interaction of clay-loaded hydrotalcite and diatomite modified wollastonite, as well as the combination of each preferred component and its dosage ratio, which not only has good strength properties, but also has excellent late-stage strength properties (that is, sustained release). good sex).

Description

technical field [0001] The application relates to a slow-release construction mortar and a preparation method thereof, which are applied in the field of construction mortar production. Background technique [0002] Building mortar is a mortar that bonds masonry block materials (such as bricks, stones, blocks, etc.) Compressive strength is often used as the most important indicator to measure its technical performance. The workability of mortar refers to whether the mortar is easy to spread into a uniform and continuous thin layer on the surface of masonry and other surfaces, and is closely bonded to the base layer. Workability includes both fluidity and water retention. The main factors affecting the fluidity of mortar are: the type and amount of cementitious materials, the amount of water, and the type, particle shape, thickness and gradation of fine aggregates. In addition, it is also related to the variety and dosage of mixed materials and additives. The existing mort...
