Influence of the mechanical activation of raw mixes on the properties of foam glass from sand sludge

This paper reports the results of mechanical activation influence investigations on foam glass properties from sand sludge. Sand sludge is a waste product from crushing and screening plants for sand and gravel production. The results show the mechanical activation efficiency of the raw mix as a structural regulation tool and the properties of foam glass from sand sludge. Mechanical activation of the raw mix for 20 min to a particle size of 50 μm allows the sample to receive granular foam glass with a bulk density of 200 kg/m3, a strength of 0.63 MPa and a water absorption of 1.4%.
