Background

Mortar is a building material with wide application in building engineering. Cement is generally applied to construction works by concrete and mortar, and is used in much smaller amount than concrete because mortar is generally used as an auxiliary material for surface treatment or bonding of masonry and the like. The ready-mixed mortar refers to a commercial mortar produced by mixing and blending in a professional factory, and is different from a field stirring mortar. Due to the problems associated with the on-site preparation of mortar, coupled with the rise in labor costs, ready-mixed mortar has come to be shipped and is being produced and used in large quantities in european countries as early as the fifties of the 20 th century. According to the national standard (GB/T25181-2010) of premixed mortar, the premixed mortar refers to wet-mixed mortar or dry-mixed mortar produced by professional manufacturers. The wet-mixed mortar is a mixture of cement, fine aggregate, mineral admixture, additive and water which are metered and mixed in a mixing station according to a certain proportion, transported to a using place and used within a specified time. The dry-mixed mortar is a mixture of cement, dry aggregate or powder, additive and other components determined according to performance, which is obtained by metering and mixing in a professional production plant according to a certain proportion, and water or matched components are added in a use place according to a specified proportion and are mixed for use. Therefore, ready-mixed mortar is produced in professional mortar plants including mixing plants and dry-mixed mortar plants. However, professional mortar plants require large equipment investment, high cost and high operation cost, and a miniature mobile mortar station is a brand new concept and can greatly promote the popularization and application of the ready-mixed mortar.
