About us
ConTec
ConTec specializes In concrete technology, in particular in rheology of cement based materials such as cement paste, mortar and concrete. Our goal is to be leading in concrete technology.
We sell vicometers and bring our knowledge to others in the form of lecturing and consulting. Our target group, both for our instruments but also for our service in consulting and lecturing are those in industry, university or research institution who work with problems related to fresh concrete properties and/or others cement based particle suspension such as cement paste, grout, repair materials, mortar, for instance self leveling flooring grout
The Viscometers
ConTec produces and sells coaxial cylinder viscometers in variable sizes or capacity
testing on material sample from 300 ml to 25 liters. The viscometers are fully automated
and computerized viscometers for fresh concrete, mortar and paste. The first viscometer

Dr. Wallevik
Dr. Olafur H. Wallevik has worked with the rheology of concrete and other cement
based particle suspensions since he finished his master thesis on that theme at the
Norwegian Institute of Technology in 1983. In the year 1987 he made the first version
of the BML Viscometer. He received his doctor degree in rheology from the same university
in 1990. His special fields are Rheology of Fresh Concrete, High Performance Concrete,
High Strength Concrete, Self-
Dr. Wallevik is the head of the concrete division at Innovation Center Iceland and the manager of ConTec Ltd.
Dr. Wallevik Rheology course: “Rheology of Coarse Suspensions, such as Cement Paste, Mortar and Concrete”, have been hold in many different countries.
The course is designed for those in industry, university, or research institution, who work with problems related to fresh concrete properties and/or other cement based particle suspensions such as cement paste, grout, repair material, mortar, for instance self leveling flooring grout.
The purpose of the course is to give a broad introduction to the basics in Rheology
of coarse particle suspensions with a main focus on fresh concrete and practical
application of it. Also, to give an introduction to coagulation rate process to
explain the mechanism which controls the workability loss. For more information about
next courses contact us info@contec.is
In additional to the viscometers and the courses we have been bringing our knowledge in to several companies in Europe and USA in the form of consulting. More information
