Dry-mixed mortar is one of the emerging dry-mixed materials in the building materials industry. Dry-mixed mortar refers to that produced by a professional manufacturer. , Mixtures of cement, which is the main binder, and fine aggregates, mineral admixtures, reinforcing materials and admixtures, which are processed by dry sieving, are mixed in a certain proportion. So how about the mix ratio of dry mortar ?
What is the proportion of dry mortar?
First, we will introduce the proportion of masonry mortar. First, let's briefly understand what is a masonry mortar. Masonry mortar is a powder used for the masonry of a wall, and is an indispensable material for the construction of masonry buildings. Under normal circumstances, the preparation of masonry mortar is relatively simple and requires less materials. The required materials mainly include cement, white ash and sand, as well as fresh water. The white ash is mainly used as aggregate. The specific ratio can be 1:0.5:0.8:3 by volume, if there are special requirements, you can Properly change the ratio, but the fluctuation of the ratio cannot exceed 0.1.
Secondly, we must introduce to everyone the ratio of plastering mortar. Plastering mortar is also an important type of dry-mixed mortar and is commonly used as a painter's head for painting. The standard ratio is 32.5Mpa cement, lime, medium sand, and water in accordance with the volume ratio of 1.5:2:3:5 to the formulation.
Finally, we introduce the proportion of ground mortar. The ground mortar is the mortar used for the initial treatment of the ground. The specific ratio needs to be in accordance with the cement, perlite, 107 glue, sand, and water volume ratio of about 1:2:0.5: The ratio of 2:4 is used for preparation. The mortar prepared according to this standard is used for ground treatment and has a good effect.
What are the advantages of dry mortar?
The quality of dry-mixed mortar is better than on-site mixing mortar, which can significantly reduce engineering maintenance costs. The quality of the mortar mixed on site at the site does not meet the requirements, and it is easy to rework or repair it in the short term, which costs more. It is predicted that after 50 years of use, the total cost of the initial construction and period maintenance of the plastering construction with dry-mix mortar is only 1/20 of the conventional plastering mortar.
Complete product range to meet a variety of different project requirements. Dry mortar manufacturers can design formulations based on different matrix materials and functional requirements, such as aerated concrete blocks, lime sand bricks, ceramsite concrete hollow blocks, fly ash bricks, etc. Highly water-retaining masonry and plastering mortars for material design; self-leveling floor mortars for high surface flatness requirements. Can also meet a variety of functional requirements, such as insulation, impermeability, grouting, repair, decoration and so on. According to incomplete statistics, there are more than 50 kinds of dry mortars.
Dry-mixed mortar is made by adding water (or supporting liquid) at the site, so it can be controlled flexibly according to the progress of construction and the amount of use. It is not subject to time restrictions and is easy to use. Mortar transportation is more convenient and can be transported together, with less restrictions on traffic conditions. Dry mortar storage period is long. The storage period of bagged ordinary dry mortar is 3 months, the storage period of bagged special dry mortar is 6 months, and the storage period of bulk dry mortar is 3 months. Bulk dry mortar should be stored in a special closed silo.
