Concrete has a hard and porous structure and is prone to cracking at many stages of its life, allowing water to enter through pores, capillary cracks and capillary spaces. This adversely affects the life, strength and aging rate of concrete. Crystallized concrete admixture waterproofing technology increases the durability and lifetime of concrete and provides waterproofing. Crystallized concrete admixture, cement-based capillary waterproofing products contain high quality cement, quartz sand and specially formulated additives. In this way, it reduces the permeability of concrete and provides waterproofing. Available in 20 Kg kraft bags.
Why Use Crystallized Concrete Admixture?
Crystallized concrete admixture is a smart concrete system similar to artificial intelligence technology. Retail customers, architects and contractors should insulate their buildings to minimize risk, protect their investments financially and protect their buildings for many years to come. Concrete is believed to be impermeable to water, but structural cracks and fractures, seismic movements such as earthquakes, natural disasters such as erosion, seasonal hot and cold differences can cause concrete to become water permeable. Corrosion in reinforced concrete structures has 3 main effects. These are oxygen, water and iron reinforcement. When you protect any of these, the corrosion environment is prevented. When water enters concrete, the steel reinforcement corrodes and rusts, causing expansion stress, further cracking and deterioration of the concrete. This cycle will continue unless water is prevented from seeping into the concrete. It should not be forgotten that the more impermeable a concrete is, the more resistant it is to factors such as moisture and acid.
Waterproofing applied from outside the concrete is usually applied with geomembranes. However, geomembranes are covered with the surface or ground boundary where they are applied. Membranes are sensitive to mechanical and chemical damage and can fail due to punctures, tears and delamination. In addition, it requires impeccable workmanship and very good protection (great attention should be paid to risks such as shovel tearing while backfilling, reinforcement molders piercing with nails, extinguishing cigarettes on the geomembrane). Concrete waterproofing products are either added directly to the concrete mix or applied to the concrete surface. Once added, the crystals chemically react with water and unhydrated cement particles to form insoluble needle-shaped crystals. These crystals fill capillary pores and microcracks in the concrete to block the pathways for water and waterborne contaminants. If water is reintroduced through an increase in hydrostatic pressure, groundwater rise or through capillary cracks and fractures, the crystals will initiate further crystallization to ensure permanent waterproofing in the concrete, working for an infinite period of time during the life of the concrete.

How Much Crystallized Concrete Admixture Should Be Used?
The amount of crystallized concrete admixtures can vary from company to company. In some companies, there are rates up to 3 percent and 6 percent of the cement ratio. An important point is the amount of kilograms that should be used, which is written in the explanations section, even if 1 percent of the cement ratio is specified. For example, 300 kg of cement is used for C30 concrete, and while 3 kg of crystallized concrete admixture should be used accordingly, application amounts up to 5 kg or even 10 kg are written. The crystallized concrete admixture, which is Santaş smart concrete system, is applied proportionally in the direction of C20, C25, C30 and C35 according to the cement class. The most important feature of our admixtures is that they are used as 1% of the actual cement ratio. Self-repairing crystallhydrates and infinitely working crystals that provide regular formation in contact with water provide lifelong waterproofing.
What are the Benefits of Crystallized Concrete Admixture?
Reduces the cost of waterproofing concrete Saves time in construction programs Reduces maintenance and repair costs Provides waterproofing reliability, comfort and quality control Safe for contact with drinking water Can be applied from negative and positive directions Increases wear and tear durability of concrete Prevents human errors Protects the entire concrete, not the surface like geomembranes. Prevents leakage in cold joints. Increases concrete strength by 10%. Closes fractures and cracks up to 0.5 mm. Resistant to chemicals between pH3 and pH11. Resists up to 15 bar water pressure. Drinking water certified. Prevents freezing of concrete. While dry ground in waterless areas is required for the application of geomembranes, crystallized concrete admixture is suitable for active operation in wet areas. Resistant against sea water.
Where is Crystallized Concrete Admixture Applied?
Parking lots Shopping malls Dams Concrete pools Concrete irrigation channels Concrete silos Concrete bridges and piers Foundation and curtain isolations Basement isolations Elevator shafts Wet areas Tunnels Water tanks Water pools
How is Crystallized Concrete Admixture Applied?
It is applied by mixing into the concrete mixer or in the form of mortar while pouring concrete.
How Does a Smart Concrete System Work?
In freezing and thawing conditions, water moving into the concrete, which is a porous structure, penetrates, turns into ice and expands. This causes the concrete to crack and disintegrate. Thanks to the crystallized concrete admixture of the smart concrete system, these situations are not observed since water cannot penetrate into the concrete.
In cases of reinforcement corrosion, corrosive chemicals from groundwater penetrate into the fractures, cracks and gaps of the concrete and corrode the reinforcement. Rust causes cracking and the tensile strength of the structure decreases. In order to protect our structures, we should use Smart concrete system crystallized concrete admixture.
In cases of chemical attack; acidic and basic chemicals such as chlorine, sulphate and lime water tend to leak into the concrete. The accumulated chemicals react and become stronger and try to crack and break the concrete. However, thanks to the Smart concrete system crystallized concrete admixture, such situations are prevented.
In the case of Chemical Reaction of Aggregate; alkaline paste cement and non-reactive silica crystals in the aggregate create chemical reactions that cause expansion and cracking by disrupting the concrete structure and reducing its strength. However, thanks to the crystallized concrete admixture, which is a smart concrete system, such situations are not seen.
How is Crystallized Additive Activated?
Crystallized admixtures, the smart concrete system, work endlessly by interacting with calcium oxide and aluminum oxide when they encounter water, forming water-insoluble crystalline carbohydrates, needle-headed crystal particles that fill capillary spaces and microcracks in concrete.
How Far Can Smart Concrete System Crystallized Concrete Admixture Go?
The crystallized concrete admixture, which has the ability to close capillary cracks and capillary gaps up to 0.5 mm in concrete, provides waterproofing and protects your structures by penetrating up to 90 cm deep.
