How to Make Concrete More Sustainable

Concrete is in many ways an ideal building material – locally available, cheap, perfect composite material when combined with steel and highly durable and easy-to-work-with when used with Sika products. However, it is not so perfect ecologically - it is the second most used substance on earth after water consuming many resources. Its most important ingredient, cement, is responsible for roughly 8% of global CO₂ emissions, whereby production is an energy intensive process.

3D Concrete Printing

Cementitious 3D construction printing (3DCP) or 3D concrete printing is a form of additive manufacturing used to fabricate buildings or construction components in completely new shapes not previously possible with traditional concrete formwork.

Waterproof Concrete

Waterproof concrete is an impermeable concrete used for long-lasting, durable watertight construction. To improve the impermeability of the concrete, water-resisting admixtures can be added. Nevertheless, design and construction of a watertight concrete structure is a system approach, and waterproof concrete is only one element of it. Water impermeability is determined by fulfilling requirements to limit water permeability through the concrete itself, the joints, installation parts and cracks.

Sprayed Concrete

Successful sprayed concrete requires the combination of many aspects of modern concrete technology especially concrete admixture chemistry, together with modern materials handling technology. The increasing demands for cost-effectiveness and the protection of health and the environment mean that sprayed concrete has been in continuous development. Thanks to more than one hundred years of experience, expert knowledge and a focus on performance and economy, Sika is able to provide the newest generation of sprayed concrete solutions.

Architectural Concrete

The ability to appreciate concrete as an aesthetically versatile construction material has led Sika to many innovations in architectural concrete. The flexibility of concrete in design enables the designer to create structures not possible with other construction materials. Combining this flexibility with Sika’s over one hundred years of experience and expertise in concrete formulation and optimization allows structures of true architectural value to be realized.

Addressing the Unwanted Impacts of Grinding Aids

Grinding aids and strength enhancers are well known for their ability to increase cement mill productivity, and the mechanical strength of mortar and concrete. However, little information is available on the potential drawbacks of their usage. To close the gap, Sika Services addresses the possible impacts on health and safety and the environment, and on cement properties in production and use.

Progress with Grinding Aids for Vertical Roller Mills

The effect of grinding aids on the comminution of cement is based on the dispersion of fine particles. It is a misunderstanding that grinding aids for vertical roller mills (VRMs) should stabilise the material bed between the rollers and the table by adhesive forces between the particles. Grinding aids reduce the polarity of the cleaved surface and the attraction forces between particles.

Enable Circularity - Make Concrete More Resource Efficient

The linear economy, or one-time use, of concrete in construction leads to a scarcity of resources and more waste at every step in the journey of that concrete material. Whereas the circular economy allows for many benefits. Explore the Sika Sustainability Circle to learn how Sika enables circularity in the concrete lifecycle.

reCO₂ver Concrete Recycling

Sika has succeeded in developing a highly efficient process to separate and reuse components of demolished concrete and increase the recycled aggregates' quality. The old concrete is broken down into individual parts - aggregates, sand, and fine powdered material - in a simple process which also binds a significant amount of CO2.

Performance Enhancer for Portland Limestone Cement (PLC)

The motives to replace clinker with supplementary cementitious materials (SCM) are well known. However, granulated blast furnace slag, natural pozzolanes, qualified fly ash and further SCM have a limited availability; the total potential replacement of the global clinker production is less than 30%. Limestone is increasingly being used as a component in Portland-Limestone cements: Sika offers an additive to enhance grinding and performance.

Sika® Watertight Concrete delivers technologically advanced solutions

First used in the UK more than 60 years ago, the Sika® Watertight Concrete system is as flexible as it ever was. Not only does the system allow for the use of cement replacements (GGBS, PFA), but also a wide range of aggregate types can be used with the system. Due to Sika® Watertight Concrete system’s impressive benefits, it is now the most widely used system of its type in the UK.
