(1) Similarities
①They are all produced and supplied by professional manufacturers.
② There are professional and technical personnel to carry out mortar mix ratio design, formula preparation and mortar quality control, which fundamentally ensures the quality of mortar.
(2) Differences
①The mortar state has different storage time. Wet-mix mortar is a wet-mix mixture made by mixing all components including water. It can be used directly at the construction site, but it needs to be used before the mortar solidifies, and the maximum storage time does not exceed 24 hours; dry-mix mortar It is a dry mixture of dry materials mixed evenly, and is supplied in bulk or bagged form. The mortar needs to be mixed with sand or supporting liquid at the construction site before use. Dry-mix mortar has a longer storage period, usually 3 or 6 months.
②The production equipment is different. At present, wet-mix mortar is mostly produced by concrete mixing stations, while dry-mix mortar caps are produced by specialized mixing equipment.
③Different varieties. Since wet-mix mortar is produced in the form of wet mixing, it is not suitable for producing mortar with higher viscosity. Therefore, there are fewer varieties of mortar. Currently, there are only mortar varieties such as masonry, plastering, and ground. Dry-mix mortar produces dry materials. , is not restricted by the production method, so there are many varieties of mortar, but the variety of raw materials is much more than that of wet mix mortar, and it is much more complex.
④The processing methods of sand are different. The sand used in wet-mix mortar does not need to be dried, while the sand used in dry-mix mortar needs to be dried.
⑤The transportation equipment is different. Wet-mixed mortar must be transported by a mixer truck to ensure that the mortar does not stratify or segregate during transportation; bulk dry-mixed mortar must be transported by tanker trucks, and bagged dry-mixed mortar must be transported by truck. </p
