System for durable and
environmentally friendly concrete
Maleki-SlagSil - The future of concrete
Maleki-SlagSil is the result of 4 years of research and development on a new concrete formulation. The result of the tests carried out on paving stones, precast concrete elements and concrete split slabs have led to a unique concrete formulation with outstanding properties:
- Permanently improved acid resistance
- Long-term resistance to salt water
- Improved freeze-thaw and de-icing salt resistance
- Earlier stackability (for paving stones)
- Maintenance of early strength, higher final strength
- Reduce shrinkage and uncontrolled expansion
- Concrete or concrete components free from efflorescence
- Environmentally friendly use of raw materials
What is Maleki-SlagSil?
Maleki-SlagSil is a specially developed binder system that combines granulated blast furnace slag and Maleki silicate activation technology. With the aid of our silicate activator Maleki-SA 200, it is possible to replace cement whilst achieving a number of interesting benefits that were previously not possible on a permanent basis. In this formulation, the cement content in the concrete is replaced 1:1 by granulated blast furnace slag (GGBS). However, the addition of GGBS or other secondary raw materials to mortars and concrete requires extremely precise adjustment to the specific application in order to achieve an optimal result.
Maleki-SlagSil is an important component in mortars and concrete to ensure lasting protection.
Cement-based materials such as concrete contain the strength-giving calcium silicate hydrates (CSH) and portlandite after hardening or hydration. While Portlandite performs important corrosion protection functions for the reinforcement in reinforced concrete, it is also responsible for undesirable concrete corrosion. Acids can dissolve Portlandite to form salts, which appear on the surface as efflorescence. The most efficient protection of the materials described is the conversion of the concrete’s own calcium ions into stable calcium silicate hydrate phases that are permanently resistant to pollutants. The transformation of the molecular structure is achieved by a specially adapted binder system. This effectively reduces the proportion of Portlandite in the end product to a minimum and significantly increases resistance to a wide range of corrosive influences. This effect was demonstrated in cooperation with external testing laboratories using X-ray analysis.
