About the Colloidal Silica in Concrete Association
The Colloidal Silica in Concrete Association (CSCA) is dedicated to advancing the understanding and responsible use of colloidal silica in concrete and cementitious materials.
CSCA brings together technical knowledge, industry experience, research, and practical application to help engineers, contractors, producers, agencies, researchers, and material suppliers better understand how colloidal silica can be used to improve concrete performance.
Our goal is to provide credible, technically grounded information that helps move colloidal silica from an emerging technology to a well-understood and effectively specified tool for the concrete industry.
Our Mission
CSCA exists to advance education, research, collaboration, and technical understanding surrounding the use of colloidal silica in concrete.
We work to bridge the gap between research and field application by providing resources that address how colloidal silica works, how it interacts with cementitious systems, and how it can be successfully incorporated into concrete mixtures and construction practices.
What We Do
Education
Develop accessible technical information and educational resources for professionals throughout the concrete industry.
Technical Resources
Provide guidance on colloidal silica fundamentals, mixture design, production, performance, durability, specification, and field application.
Industry Collaboration
Connect researchers, material suppliers, engineers, producers, contractors, agencies, and other industry professionals to encourage knowledge sharing and continued advancement of the technology.
Responsible Adoption
Support informed specification and use of colloidal silica based on sound concrete science, appropriate testing, and demonstrated performance.
Dr. Jon Belkowitz – President
Dr. Jon Belkowitz is a concrete materials researcher, educator, and consultant specializing in cementitious materials, nanotechnology, and the use of colloidal silica in concrete.
His work has focused on understanding how nanoscale materials influence cement hydration, concrete microstructure, mechanical performance, and durability, with an emphasis on translating laboratory research into practical solutions for concrete production and construction.
Jon has worked throughout the United States and internationally on concrete research, materials development, testing, troubleshooting, and technical education. He holds a Master of Materials Science from the University of Denver and a PhD in Mechanical Engineering from Stevens Institute of Technology, where his doctoral research focused on nanotechnology in concrete.
As President of CSCA, Jon works to advance technically sound education, research, and industry understanding surrounding the effective use of colloidal silica in concrete.
Whitney Belkowitz
Whitney Belkowitz is a concrete industry professional with nearly two decades of experience spanning laboratory testing, field applications, concrete research, technical education, and the implementation of emerging concrete technologies. She holds a Bachelor of Science in Civil Engineering from the University of North Dakota.
She began her career in concrete materials in 2007, working in laboratory and field environments evaluating fresh and hardened concrete properties, durability, and material performance. Her work has since expanded to include research, technical communication, industry education, and the practical application of advanced materials in concrete.
Whitney has contributed to research supported by organizations including the National Science Foundation and the U.S. Army Corps of Engineers and has co-authored technical and industry publications addressing concrete materials and performance. Her experience working with researchers, producers, contractors, engineers, and material suppliers provides a practical perspective on moving new technologies from research into real-world concrete applications.
Through CSCA, Whitney works to expand access to credible technical information, strengthen industry collaboration, and support informed adoption of colloidal silica in concrete.
