Abstract
Purpose: The aim of this work is to study the physical and mechanical properties of cement brick modified by ultrafine quartz waste filler. Methodology: Mechanical grinding is used to obtain ultrafine particles. Research findings: The effective ratio for ultrafine activated quartz is determined to be 30:70. The use of ultrafine filler based on activated quartz waste allows increasing the density from 2 to 4 % and strength from 20 to 30 % and also reducing its thermal conductivity down to 8 %.Practical implications: A fabrication technique is proposed for cement brick with improved physical and mechanical properties using quartz wastes in the amount of 30 % of the cement volume. Value: A denser structure of cement brick is obtained using a 4 % dry activation, when the volume fraction of quartz waste particles is less than 20 microns in size.
