Abstract [en]

The purpose of this investigation has been to evaluate the effect of quartz filler on concrete strength and microstructure, and to see if it is possible to replace cement with filler without loss of strength. Fillers are materials whose function in concrete is based mainly on size and shape. They can interact with cement in several ways; to improve particle packing and give the fresh concrete other properties, and even to reduce the amount of cement in concrete without loss of strength. Quartz was chosen as filler material, since it is inert and is available both as a by-product and a natural raw material. Different amounts of filler were used in the various experiments, as well as different particle size distributions. The results are positive: fillers can partially replace cement and at the same time improve the properties and the microstructure of the concrete. This research is part of a larger project that aims to find uses for by-products in concrete.
