Concrete and Cement Mortar: Improved Chemical Admixture Systems

Innovative Chemical Admixture Solutions for Cement and Concrete

Improved chemical admixture systems that are added to concrete and cement mortar include a variety of materials. Specifically, they aim to enhance the performance and improve the mechanical and physical properties of construction materials. Furthermore, these materials are added to concrete and cement mortar during production or operation to improve their properties. Additionally, these additives can be in the form of auxiliary materials or chemically active materials. Therefore, they are considered an essential part of modern construction technology. In this article, we will discuss the definition of concrete and cement mortar. Moreover, we will also mention the most important chemical admixture systems that improve them.

Definition of Concrete and Cement Mortar

Concrete and cement mortar are basic construction materials used in the field of construction and civil engineering to build various structures and foundations. Here is a definition of each:
1- Concrete:
Concrete is an artificial material composed primarily of a mixture of cement, aggregate and water, which is mixed and poured into different shapes before it hardens and becomes strong. Concrete is made up of cement (binding material), aggregate (filling material), water (to activate the hardening process) and additional materials such as additives to improve physical or mechanical properties.

Concrete is a versatile material and is used in the construction of buildings, bridges, sidewalks, roads and other structural structures.
2- Cement mortar:
Cement mortar is a material commonly used to connect tiles, cover surfaces or to bind building units such as blocks or bricks. Cement mortar is basically a mixture of cement, sand and water, where cement acts as a binding agent that binds the sand particles together to form a strong and durable material. Other materials such as chemical property enhancers or fibers can also be added to increase the strength or resistance of the mortar.

Concrete Strength Enhancement Systems

These systems include a wide range of chemical additives that improve the performance of concrete. They enhance the hydraulic hardening reactions in concrete, increasing its ultimate strength and durability. These chemical additives may include silicates, and non-metallic materials such as pesticides.

2. Shrinkage Reduction Systems
   These systems are used to reduce the thermal and plastic shrinkage of concrete. They improve the distribution of moisture in the concrete, which reduces its shrinkage and thus the occurrence of cracks. The additives used in these systems include shrinkage reducing materials such as polymers and fiberglass.
3. Concrete Corrosion Resistance Enhancement Systems
   These systems aim to protect concrete structures from chemical and electrical corrosion. Chemical additives are used to form a protective layer on the surface of the concrete that resists corrosion. The additives used may include corrosion inhibitors such as chemical-resistant polymers.
4. Performance Enhancement Systems for Harsh Environment
   These systems rely on additives that make concrete resistant to harsh environmental factors such as chemical and biological corrosion, oxidation, freezing and thawing, and others. Materials resistant to harsh environmental factors such as cured polymers are used. 5. Flowability Enhancement Systems

These systems include additives that enhance the concrete’s ability to flow and form without losing its mechanical properties, making it easier to pour and reducing the need for training. The additives used include molding inhibitors and flow aids.

Flexibility and Durability Enhancement Systems

These systems include additives that make concrete more flexible and durable, increasing its ability to withstand external deformations and stresses. They include crack inhibitors and fiber-reinforced materials.

Finally, concrete and cement mortar are essential in the field of construction and civil engineering and are widely used in the construction of various structures due to their strength and durability. Chemical additives are carefully used to improve their capabilities. These chemical systems are constantly evolving with technological advancements and are available in various types to meet different needs in the field of construction and construction. Therefore, they must be selected according to the technical specifications specified for each application, and they must be selected based on the concrete needs and specific construction conditions.
