Good, Clean Design

TX Active photocatalytic cement was first used in 1996, in the production of the three graceful precast concrete panels that form the “sails” of the landmark Dives in Misericordia Church in Rome, designed by Richard Meier.

Since then, our research, development and improvement efforts have been an intensive, ongoing focus. Early photocatalytic cements were effective in keeping surfaces clean; the levels of photoactivity achievable with TX Active cement is such that it actually abates the organic and inorganic substances responsible for air pollution.

For more than a decade, our technology center has been studying photocatalysis and applying its applications in cementitious materials. Among our findings: cementitious materials represent the ideal solution for spreading photocatalysts widely and evenly over both the horizontal and vertical surfaces of architectural and structural elements.

Photocatalysis : The Power of Light

Photocatalysis is a natural phenomenon in which substances known as photocatalysts accelerate the n processes that occur in nature. This promotes faster decomposition of pollutants and prevents them from accumulating.

Ever-increasing air pollution in urban areas has compelled researchers to take advantage of photocatalysts to abate the noxious substances that contaminate the environment.

Simply by using light energy from the sun, photocatalysts accelerate the formation of strong oxidizing reagents, which result in the decomposition of organic and inorganic pollutants. For over a decade, photocatalysis has been applied to various materials—glass, ceramic, cementitious binders—to obtain a “self-cleaning” effect.

Architecture in a Whole New Light

TX Active cement was originally developed to achieve Richard Meier’s strict design specifications for his Dives in Misericordia Church. The goal was to provide pure, white, eyeopening brilliance with aesthetic qualities that will endure throughout the ensuing decades.

Since then, TX Active has been the cement of choice for many prestigious architectural projects in which the quality of materials and final appearance were equally important in achieving the architect’s original vision. In addition to providing traditional concrete properties, concrete produced with TX Active cement offers “self-cleaning” properties that help retain the structure’s original beauty for years.

Preserving the Environment

TX Active’s photocatalytic properties help protect the environment by abating noxious substances produced by activities such as industry, transportation and residential heating systems. It can be used anywhere cement-based products are used, including:

Horizontal Structures
  • Interlocking concrete pavers
  • Concrete pavements
  • Concrete overlays
  • Concrete roof tiles
  • Concrete sidewalks
  • Pervious concrete

Vertical Structures
  • Architectural precast panels
  • Tilt-up concrete panels
  • Cladding elements
  • Noise barriers for roads and highways
  • Concrete median barriers
