MINERAL POZZOLAN
for CEMENT + CONRETE
İncal Buildin is a high-quality natural zeolite carefully selected and processed to serve as a top-tier supplementary cementitious material (SCM) pozzolan in cement and concrete production. This premium-grade pozzolan offers numerous benefits for sustainable construction practices, contributing to reduced environmental impact while enhancing the strength, durability, and chemical resistance of cementitious materials.
Pozzolan Properties of Buildin
Pozzolans are natural or artificial materials rich in silica and alumina that react with lime and water during cement hydration, forming calcium silicate and calcium aluminate hydrates. İncal Buildin contains predominantly active silicon oxide (SiO2) and aluminum oxide (Al2O3), with additional ferric oxide (Fe2O3) and other oxides. The active SiO2 content of pozzolans is crucial for effective pozzolanic performance, and zeolite boasts an active SiO2 content ranging from 44% to 54%.
Effect of Active SiO2 Content
on Activity + Strength
The high reactivity of zeolite is demonstrated through Frattini tests, where it achieves close to 100% effective hydroxide binding (Ca(OH)2). This indicates that a significant portion of the lime produced during cement hydration reacts with the pozzolan, leading to increased strength and performance of the cementitious materials. The active SiO2 content of İncal Buildin ensures superior strength and durability of concrete structures.
Advantages of Buildin Application
Cost Savings in Cement Production
İncal Buildin can be used as a partial substitute for cement in concrete production, resulting in cost savings for cement manufacturers. This cost-efficient approach allows producers to maintain the desired cement grade while reducing production expenses.
Environmental Benefits and Reduced Carbon Footprint
By utilizing İncal Buildin in cement and concrete production, the industry can lower its carbon footprint. The pozzolan's efficient use as a cement replacement reduces the need for clinker production, which is a significant source of greenhouse gas emissions in cement manufacturing.
Enhanced Long-Term Strength
İncal Buildin’s pozzolanic reaction with cementitious compounds leads to a gradual increase in strength over time. This property ensures the long-term durability and structural integrity of concrete, making it an ideal choice for sustainable construction projects.
Improved Tensile Strength and Durability
Incorporating İncal Buildin into concrete mixtures enhances the material's tensile strength and durability. The resulting concrete is more resistant to cracking and structural deterioration, even in harsh environmental conditions.
Increased Resistance to Chemical Attack
The addition of İncal Buildin improves concrete's resistance to chemical attacks, such as exposure to chlorides, acids, nitrates, and sulfates. This is particularly beneficial in environments where concrete structures are susceptible to chemical degradation.
Mitigation of Hydration Heat and Alkaline Reactivity
In massive concrete structures and high-temperature conditions, the inclusion of İncal Buildin effectively reduces the risk of excessive heat during cement hydration. This mitigates the potential damage caused by the alkaline reactivity of certain aggregates, ensuring the long-term performance of the concrete.
Economic + Ecological Savings
in Cement Production
The use of İncal Buildin as a cement substitute offers economic and ecological advantages for cement producers. Its high active SiO2 content allows for effective cement production cost reduction while maintaining the desired cement grade, making it a sustainable and financially viable choice.
Cement Blends with Buildin Addition
Concrete mixtures blended with İncal Buildin exhibit favorable properties when combined with cement. This flexibility in the production process enables adjustments to external environmental factors, such as CO2 allowances or the availability of other supplementary cementitious materials like granulated blast furnace slag.
Properties of Concrete Treated with Buildin
Research on concrete treated with İncal Buildin showcases promising results.
Substituting up to 10% of cement with İncal Buildin increases compressive strength by 15%.
Water absorption is reduced by 2.3 times, leading to improved density and ultrasonic pulse speed of concrete.
Closed porosity increases, enhancing concrete's resistance to freezing and thawing by 3.3 times.
Buildin as an Admixture
for Concrete Production
Zeolite has been classified as a Type II admixture for concrete production following the STN EN 206 + A1 standard, using Portland cement EN 197-1. Its universally valid k-values determine the optimal substitution percentages by weight: k = 1.1 for up to 10%, k = 1.0 from 10.01% to 15%, and k = 0.8 from 15.01% to 20%. The versatility of İncal SCM allows for up to 20% weight substitution of cement, resulting in significant economic and ecological savings.

Concrete Products
İncal Buildin, as a desiccated and ground zeolite concrete additive, significantly enhances the properties of cementitious materials. With its high active SiO2 content, it improves mixture stability and eliminates sulfate corrosion. Its specific surface area is high, while its density is low, making it an ideal blend for optimizing cement production and concrete performance.
Manufacture of Concrete Products
İncal Buildin’s multifunctional role extends to the production of cast floors, roofs, and precast concrete products. By stabilizing the mixture, İncal Buildin facilitates handling, reduces flux, and enhances the cement slurry's sealing properties, making it ideal for challenging applications in aggressive sulfate environments and underground sealing walls.
Buildin in Lightweight Concrete
İncal Buildin can replace fumed silica as a lightweight cement additive, resulting in reduced density, increased compressive strength, and improved thermal insulation. Its use in lightweight aggregate contributes to the preparation of structural lightweight concretes, which are desirable in certain construction applications.
