Abstract

The invention discloses a brick making mortar which comprises the following components in percentage by mass: combined cement, casting waste sand, yellow sand, fly ash, slag powder, attapulgite, crushed calcite, cellulose ether, redispersible polymers and polysiloxane powder. Compared with the prior art, the addition proportion of the combined cement is properly added into the brick making mortar, and the casting waste slag and attapulgite are used instead of part of yellow sand, thereby relieving the problem of reduced supply of yellow sand and lowering the manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a mortar for making bricks. Background technique [0002] Dry powder mortar refers to a granular or powdery mixture of dried and screened aggregates, inorganic gelling materials and additives in a certain proportion. The additives are water-retaining agents, thickeners, polymers, etc. It is transported to the construction site in bags or in bulk, and can be used directly after adding water and mixing. Compared with traditional on-site mixing mortar, dry powder mortar has the following advantages: high quality, rich variety, good construction performance, convenient use, green environmental protection, economy, etc. Among them, the aggregate used in dry powder mortar is mainly natural yellow sand, which has a large demand, but yellow sand is a non-renewable resource, and its price is also soaring. With the protection of natural rivers in the country, the exp...
