Organic mortar is a new type of environmentally friendly building material, and its main feature is the mortar that uses organic gelling materials as binders. Mortar has attracted more and more attention because it not only has good construction performance but also can reduce environmental pollution.

Advantages of Organic Mortar
The gelling agents of mortar mainly include methylcellulose, hydroxypropyl methylcellulose, carboxymethyl cellulose, etc. After these gelling agents are mixed with water, they can form a stable colloidal solution, which can firmly bind sand, stones, and other particles together. Compared with traditional cement mortar, mortar has the following advantages:
Good environmental performance
The mortar uses an organic gelling agent, which does not contain harmful substances, will not produce any pollution during the construction process, and will not cause harm to the environment. Compared with traditional cement mortar, it is more environmentally friendly and can better protect the environment.
High compressive strength
Under the correct use method, the compressive strength of mortar is equivalent to that of traditional cement mortar. At the same time, it also has good water resistance and durability and can maintain stable performance in harsh natural environments.
Compared with traditional cement mortar, the construction method of organic mortar is easier. Due to the good adhesion and fluidity of organic mortar, it can automatically eliminate air bubbles and reduce the appearance of hollows, so construction is easier.
The preparation process of mortar is relatively simple and can be completed in a short period. In addition, the raw material cost of mortar is relatively low, so the cost is also relatively low.
In short, mortar has the advantages of good environmental performance, high compressive strength, convenient construction, and low cost. Therefore, in the construction industry, mortar has been more and more widely used.
Characteristics of organic mortar
Organic mortar can effectively resist chemical corrosion because it uses an organic gelling agent, which can resist the erosion of chemicals such as acids and alkalis. Therefore, mortar has been widely used in the construction of chemical, food, pharmaceutical, and other industries.
Good crack resistance
Due to the good stretchability of mortar, it can relieve the stress caused by temperature changes or deformation of the building itself, so it has good crack resistance. This is also the reason why mortar is used in some construction projects that require anti-seismic and anti-crack.
Wide range of applications
Organic mortar is not only suitable for the construction industry but also can be widely used in water conservancy, transportation, geology, environmental protection, and other fields. For example, mortar can be used in water conservancy projects such as seepage prevention, plugging, and reinforcement; it can also be used in traffic projects such as road repair and bridge reinforcement; it can be used in geological projects such as tunnel support and basement waterproofing; it can also be used in chemical wastewater. Treatment, sewage treatment, and other environmental protection projects.
Limitations of Organic Mortars
Low compressive strength
Compared with cement mortar, the compressive strength of organic mortar is lower, generally only tens to hundreds of kilopascals, so it may not be suitable for some occasions that require higher structural strength.
Long hardening time
Because the gelling mechanism of organic mortar is different from that of cement, its hardening time is usually longer, and it generally takes 3-7 days to meet the use requirements. This will have a certain impact on the construction progress, and the construction party needs to make sufficient time arrangements in advance.
The cost of raw materials for organic mortar is relatively high, and its production process is relatively complicated, so its price is generally high. This is one of the reasons why organic mortars are not widely used in some low-cost projects.
Environmental protection issues
The organic gelling agent used in organic mortar may contain some harmful substances, which will have a certain impact on the environment. Therefore, it is necessary to pay attention to environmental protection and safe production during the use of organic mortar.
To sum up, although organic mortar has many advantages, there are still some limitations and disadvantages. Therefore, in the specific application, it is necessary to choose according to the actual situation, weigh its advantages and disadvantages, and choose the most suitable material to meet the engineering needs. At the same time, the continuous advancement of science and technology is also expected to further improve and perfect the performance and quality of organic mortar, and increase its scope of application and application value.
