Abstract

Abstract: This paper deals with the problematics of utilization of continuous hydrostatic weighing to monitor the volume changes in research of new building materials. The aim of this paper is to describe the abilities of continuous hydrostatic weighing and to present the capabilities and results of measurements made using this method. The volume changes in this paper were measured using the laboratory scales connected to computer. The volume changes were studied on the cement-based composites containing up to 40 wt.% of cement substitution by secondary raw material. The high temperature fly ash, packing glass, foundry sand and slag were used as the cement substitution. This research shows that the continuous hydrostatic weighing produces results comparable to other methods for volume change measuring. Therefore, this method can be used for volume change monitoring without using any economically demanding laboratory equipment.
