Natural Pozzolans Cement

In place of pure Portland cement, which is frequently used in building materials including concrete, masonry blocks, masonry mortar, bricks, and other construction units, pozzolans can be combined with lime (or Portland cement) to create mixed cements.
In civil projects, mass concrete, regulated low-strength materials, grout, mortar, precast and prestressed parts, structural concrete, and concrete pipelines are among the materials that use natural pozzolans.

Applications of Natural Pozzolans in Concrete

1. Concrete Structure

Natural pozzolans are used to concrete constructions either by adding natural pozzolan at a certain rate or by substituting cement with other elements.
The natural pozzolans improve the plastic qualities of concrete, making the mixture more cohesive and workable, which lessens segregation and helps with consolidation. They also decrease permeability and increase durability.

2. Prestressed and Precast Concrete Components

Precast and prestressed concrete elements gain sufficient durability and strong early strength thanks to the presence of natural pozzolans. These are necessary requirements when using precast and prestressed concrete elements in the construction of buildings, parking garages, and bridges.
The early strength is high, which facilitates formwork removal early. However, constructions exposed to moderate to severe environments require a high level of durability.
Precast and prestressed concrete structures are typically classified as being in the moderate to severe exposure category. elevated responsiveness A natural pozzolan called metakaolin is used in the production of prestressed and precast concrete components

3. Large-scale concrete

Large dams are now constructed with concrete that contains natural pozzolans.
It lessens the heat of hydration, which lessens the thermal pressures that might lead to cracking in concrete. the leader of the dehydration effort.
It also reduces the possibility of alkali-silica reaction expansion and increases sulfate resistance.

4. Pipes Made of Concrete

There are several advantages to using a natural pozzolan for making concrete pipes. It uses less cement while maintaining the workability required for pipe fabrication.
The natural pozzolans reduce permeability and increase pipe density made of concrete.
Ultimately, there is less chance of hairline crack development because natural pozzolans reduce the heat hydration of concrete.

5. Masonry Units Made of Concrete

Concrete masonry units are made from natural pozzolans. It increases the concrete’s fluidity and cohesiveness, which aids in the compaction of the material needed to make masonry units. The growth of efflorescence on concrete brick units is reduced when natural pozzolans weaken the durability of concrete.

6. Managed Low-strength Substances

Instead of using compacted soil, a mixture of natural pozzolan, Portland cement, water, and fine aggregate is used to create regulated low-strength fill material. Compaction is not required to attain the required strength, density, and load-bearing capability.
The regulated low-strength materials are primarily used to replace compacted granular materials in situations where installation and subsequent settling may present challenges.
Furthermore, the regulated low strength materials have been utilized for culvert backfill, floor fills, pipe bedding, foundation sub-base, paving sub-base, sewage lines, abandoned tank filling, and manholes.

7. Mortar and grout

Natural pozzolans are used in grouts for a variety of purposes, including increased sulfate resistance, decreased permeability, decreased heat of hydration, improved workability, and reduced permeability.
The inherent pozzolans in mortar may have an impact on other important characteristics like as setting time and binding strength.
