Full-scale tests for housing

One of the tasks in the Brite EuRam project Self-Compacting Concrete, SCC, treats production system for housing. The aim is to take advantage of the data and experience obtained from the other tasks, which include small or laboratory testing, and use this information in the full-scale tests. Important factors for full-scale tests are the handling and placing of concrete, formwork, surface quality and the effect of steel fibre reinforcement. Other important issues are to study the environmental effects and the economic effect of using self-compacting concrete. Full-scale tests using SCC with and without fibres have been carried out in an office building downtown Norrkoping, Sweden. The total volume of SCC that was cast was approximately 3000 m(3). A thorough follow-up and documentation according to a test program including both walls and floors was made for eight casting (approximately 200 m(3)). Most of the castings obtained good quality. When the results was unsatisfactory the reason seems to be the problem to control the moisture in the aggregate at the concrete plant.
