1. What is dry mortar?
Dry mortar originated in Austria and Finland.
In 1958, a Finnish company began to develop dry mortar products for thin layer mortar.
But since 2005, it has become popular in the world.
Why is that?
As a new “green” building material, dry mortar has the characteristics of high quality, low cost, safety, and environmental protection
It not only improves the utilization rate of cement but also reduces the amount of cement used and reduces the construction cost.
It has the function of replacing traditional mortar additives, so the dry mortar equipment plays a key role in the industry.
In order to encourage the promotion and application of dry mortar admixtures, countries around the world have issued policy regulations.
In order to reduce pollution, countries began to make it mandatory for construction sites to use dry mortar.
That means you can’t buy sand and cement separately,
And can only buy an independent package of dry mortar and dry mortar production equipment for mortar production.
The demand for dry mortar should be more than 2 billion tons, but the actual output of dry mortar is only 64 million tons.
In addition, according to the 2007 Cement Industry Analysis and Investment Consulting Report,
With the acceleration of industrialization and urbanization in various countries and the steady implementation of new rural construction,
In the next 20 years, cement and other basic raw materials for construction projects will maintain high demand.
This means that there is a huge gap in the market in this industry!
Bring you a huge profit!
Okay, so now to get back to business,
Dry mortar refers to the dry sifted treatment of aggregate (such as quartz sand), inorganic cementite materials (such as cement), and additives (such as a polymer) according to a certain proportion of physical mixing and into a granular or powder.
Material shipped to the site in bags or bulk, mixed with water, and ready for immediate use.
Also known as mortar dry powder, dry mix, dry mix powder, some building adhesives also belong to this category.
Dry mortar plays the role of bonding, liner, protection, and decoration with a thin layer in the construction industry, which is widely used in construction and decoration engineering.
1.1 Raw material composition of dry mortar
Dry mortar generally USES inorganic adhesive, such as ordinary Portland cement, high aluminum cement, special cement, gypsum, anhydrous stone
The amount of inorganic cementitious materials generally accounts for 20% ~ 40% of dry mortar;
Most fine aggregates are quartz sand (fine sand), the fineness modulus is usually 1.6~2.2, and the dosage is large.
Generally, pretreatment, such as drying and screening, is needed to ensure that its particle size and quality meet the requirements of the formula;
Sometimes fly ash and slag powder are added as admixtures.
Organic viscose general amount is very small, in 1% ~ 3% or so, but the effect is huge.
Common ones are as follows:
- 1, coagulant, use it to obtain the expected setting time.
- 2. Retarder, mainly used in gypsum mortar and gypsum-based joint filler.
- 3, air entrapment agent, through the physical action of introducing microbubbles in the mortar, reduce the density of mortar, better construction.
- 4. Fiber, divided into long fiber and short fiber. Long fibers are mainly used for reinforcement and reinforcement; Short fiber is used to influence the performance and water requirement of mortar.
- 5, defoamer, dry mortar production line is mainly used to reduce the air content in mortar. The main use of inorganic carrier hydrocarbons, polyethylene glycol and other additives as pigments, thickeners, plasticizers.
- 6, hydrophobic agent, can prevent water infiltration into the mortar, mortar can still remain open for steam diffusion.
Dry mortar Often according to the requirements of the product formula to choose, to improve the mortar workability, stratification, strength, shrinkage and frost resistance, and other indicators.

- 2. Immature technology.
- 3. Mortar varieties are not abundant.
- 4. Big investment.
Although dry mortar meets all kinds of resistance in the process of popularization and use,
But the historical inevitability of replacing traditional mortar is hard to change.
Large and medium-sized cities in various countries have also shown great interest in the use of dry mortar,
The extensive media propaganda and the scientific and technological progress made by numerous scientific and technological workers will create favorable conditions for the development of dry mortar.
Like the development of commercial concrete, it will usher in a brilliant spring.
1.3 You should know: dry mixed mortar production process
The dry mixed mortar production process mainly includes: aggregate pretreatment, raw material lifting and storage, batching measurement, mixing and stirring, finished product packaging storage, or bulk.
- 1, the aggregate
Sand aggregate is mainly quartz sand, river sand, broken limestone, and so on.
The impurity content and particle size distribution must be tested before use. The sand containing impurities must be washed and dried. Its final humidity must be less than 0.5%.
Dry, dry river sand, coarse sand.0 mm) with good fluidity, the shape of sand particles is round Angle and the stacking Angle is small.
In addition to the final product itself, these characteristics also have an important impact on the selection and design of dryer and sieve.
- 2. Cementing materials and fillers
Cementing materials and fillers followed.
The function of cementing material is to stick the particles in the sand together and produce a certain strength after solidification.
The cementing materials listed above mainly include cement, gypsum, lime, etc.
The use of different cementing materials will directly affect the properties of the finished product such as waterproofing, shrinkage, strength, etc.
Therefore, the quality must be inspected in the factory to ensure consistency with the formulation requirements in the laboratory.
White cement also requires a color test.
- 3. Lightweight aggregate
There are also lightweight aggregates such as expanded perlite, foamed EPS particles, vermiculite, foamed microbeads, etc.
Their characteristics are bulk density, heat transfer coefficient, particle size, strength, water absorption, and so on.
These properties make the measurement more complex, such as the need for additional volume measurement.
The requirements and dynamic parameters of the mixer are also different.
For example, the expansion of perlite is fragile, in the process to avoid as much as possible redundant links, mixing time is not easy too long.
When using foaming EPS particles, pay attention to the shape and size distribution of the particles, and select appropriate packaging to avoid segregation.
- 4. Chemical additives
Solid powder and liquid. Liquid additives must be added in a spraying manner.
Additives are measured in trace amounts and are usually mixed in a ratio of one to ten million.
So it is very important to measure and stir accurately.
In addition to the properties mentioned above, the use of additives must take temperature into account.
It should be used within the operating temperature range given by the additive supplier, including storage and transportation.
The fluidity of additives is poor, and the working temperature.
1.4 What are the advantages of dry mixed mortar

2. Dry mortar production equipment
Ok, after introducing the dry mortar, let’s learn about the equipment to produce the dry mortar
(Although the number of words is a bit much, But I think I am more tired than you, haha, I believe you will learn a lot!)
Again, let’s start with the history of dry mortar equipment first.
The dry mixing mortar equipment was developed by a Finnish company in 1958.
At present, more and more dry mixed mortar equipment is promoted in the world. In Europe, about 50 million tons of dry mixed mortar is produced every year, of which Germany accounts for one quarter.
In developing countries, the dry mixed mortar will be more and more popular in future development.
Now the rural construction, dry mixed mortar, real stone paint, and other materials will be more and more demand,
The development of the dry mixed mortar equipment industry is also getting better and better.
