Method for automatic quality assurance of self compacting concrete210

Purpose and goal

The project directed to gain knowledge on fresh concrete behavior of self compacting concrete in order to develop quality assurance method at site delivery. The targeted goals were: Functiion in laborative environment Documentation of pilot study and litterature study, Specification of criteria, function in full scale. Function of electronic system and system of communication. Report

Expected results and effects

It is important to describe the properties of self compacting concrete, SCC, correctly by a a operator independent method The work has been focused to understand these properties and how they could be documented. The project has shown interesting possibilities to record the properties. The result of the project, i. e. the test method, is operator independent and records the properties in a sufficiently accurate way. A quality assured product increase the reliability of the product. A possibility is to increase the share of SCC up to 50 % of all produced ready mixed concrete.

Planned approach and implementation

Initially, a prototype was developed that however was considered not to be reliable. After analyses and discussions within the project group it was decided to contact external expertise from Iceland. A complete new method was thus developed in laboratory at the projects last half year. The short duration of the work was possible using the long experience of the concrete experts that rapidly understood the challenges of the work and type of activities to solve upcoming problems.
