Efficient mixing of bulk building materials for building structures

Abstrakt

The study presents an analysis of the efficiency of mixing bulk building materials used in binder-based composites. The research focused on evaluating the impact of mixer blade geometry on the homogeneity of the resulting mixture. Comparative experiments were conducted using traditional straight-blade and newly patented spiral-type mixers operating at 366 rpm. The degree of homogenization was assessed through the mass heterogeneity coefficient () for the lightest composite component. Results showed that the innovative mixer design significantly reduced mixing time by approximately 40 seconds and improved the uniformity of the mixture ( < 12 %) compared to conventional mixers. The findings demonstrate that blade geometry plays a critical role in optimizing the mixing process, enhancing material consistency, and reducing air entrainment, which contributes to improved mechanical properties of construction composites.
