The building materials the TITAN Group provides are not a finished product. They are components for the construction industry. Undoubtedly the full life cycle analysis of TITAN products engages a variety of actors including customers, designers, architects, civil engineers, as well as construction and demolition companies. We closely follow developments in our sector and have embarked on a new effort to meet our aims in this field, so as to facilitate the adoption of best practices leading to sustainable construction.

Three main areas of focus have been defined as priorities at Group level: 

  • Cement qualities and properties affecting concrete 
  • Durability and life-cycle of concrete 
  • Environmentally friendly types of cement and concrete

Our advantage of being a producer of both cement and concrete, may help us bridge the knowledge gap between the two areas. Furthermore, TITAN is seeking to engage with customers and other stakeholders who have a critical role in the accomplishment of such a task.

Indicative projects that the Group Research and Development Department implements include:

Blended cements: The most efficient way to reduce CO2 emissions produced by the cement industry is possibly the replacement of clinker with other substitutes. Blended cements have a long history in Greece, having been used widely for decades. Extensive research is currently undertaken by R&D on new blended cements in order to further reduce their clinker content.

In countries with little or no tradition in blended cements, it is sometimes necessary to change the industry’s perception that high clinker content means high quality cement. Still, we have managed to produce blended cements in FYROM with a 50% clinker replacement rate and slag cement in Egypt, although generally the markets are still oriented towards traditional types of cement. For road construction TITAN offers offer a hydraulic binder with a clinker content of only 25%. 

New concrete products: Our research aims to provide more sophisticated concrete products designed to meet the exact needs of our clients, reducing the use of non-renewable resources and minimizing the environmental impact of construction projects. There are numerous examples of this approach such as the successful use of previous concrete and self-compacting concrete in the RMX plants of TITAN America, which produce concrete with increased water permeability and concrete that reduces labor requirements and eliminates the need for vibration. In the Greek Ready Mix plants lightweight screeds with high air content are used in place of denser mortars that require a larger quantity of raw materials. Other research projects aiming to replace aggregates from quarries with by-products of other industrial processes are also under way.

Pro Ash και EcoTherm:

Differentiating product capacity and branching out best practices

Manufactured from the fly-ash by-product of burning coal, ProAsh is a highly sought-after concrete additive that enhances the characteristics of concrete and reduces the amount of Portland cement required in the production of concrete. One of the primary ingredients in concrete, Portland cement, causes one tonne of CO2 emissions for every ton of Portland cement produced. The United States consumes over 100 million tonnes of Portland cement annually. Separation Technologies’ Big Bend location is capable of producing up to 250,000 tonnes of ProAsh per year, which will create an equal amount of CO2 offsets through the displacement of Portland cement in concrete mixtures.

Separation Technologies’ ProAsh production facility has won preliminary approval from the Chicago Climate Exchange Offsets Committee for carbon dioxide emission offsets at Teco Energy’s Big Bend Power Station. The Chicago Climate Exchange (CCX) has determined that producing ProAsh through Separation Technologies’ patented electrostatic separation process results in the reduction of CO2 output and qualifies for offsets under CCX guidelines.

In addition to ProAsh, Separation Technologies produces Ecotherm, a carbon-rich material that can be used as a substitute for coal and is regarded as a valuable commodity in light of the rising cost of fuel and the need to develop sources of energy while minimizing CO2 footprint.
