Problems solved by technology
Since the mortar materials are purchased separately, the element content of the main materials is not measured before use, resulting in unstable mortar quality; materials are transported in bulk, causing dust pollution on the construction site and during transportation; materials are unpacked, weighed, and mixed in proportion at the construction site. There are many uncertain factors, and the workers will inevitably measure inaccurately, which will also affect the construction quality.

The present invention discloses one kind of mortar powder for building and its preparation process. The mortar powder is especially suitable for use in mortar for laying wall at normal temperature and low temperature and plastering. It consists of 32.5-grade Portland cement or slag cement 49.5-59.5 wt%, slaked lime 39.5-49.5 wt%, and admixture 1-5 wt%. The mortar powder is used in producing mortar through simple operation, and has convenient use and capacity of ensuring high and stable construction quality.
Description
technical field [0001] The invention relates to a dry powder mortar for construction and a preparation method thereof, which is particularly suitable for the mortar used for building and plastering walls at normal temperature and low temperature. Background technique [0002] Construction mortar is used in construction works. Since the mortar materials are purchased separately, the element content of the main materials is not measured before use, resulting in unstable mortar quality; materials are transported in bulk, causing dust pollution on the construction site and during transportation; materials are unpacked, weighed, and mixed in proportion at the construction site. There are many uncertain factors, and it is inevitable for workers to measure inaccurately, which also affects the construction quality. Contents of the invention [0003] A prepared dry powder mortar is provided for direct use on the construction site. [0004] Its ratio and preparation method are as ...
