Powdered bricks have pozzolanic properties and can form an additional CSHphases if they are used as inter-grinding or blending substances within the matrix. Given this, an experimental study was carried out to examine the effect of brick powders, when added to cement, on hydration formation and strength development phases. A range of powder samples were selected to examine their influence on mortar properties. Specimens were also prepared with the fly ash for comparison purposes. Experimental work was conducted to evaluate the effect of the material on the consumption of Ca(OH)2 and properties of mortars containing brick powders in a mixture with cement. Also, a reaction of the powdered bricks with Ca(OH)2 analogous was also establish. The use of fly ash was found to have a positive influence on the concrete properties, such as workability, bleeding and strength development.
In addition to the brick powders, concrete powders of a varying finenesses were tested to examine their influences on mortar properties. The workability and strength development of the mortar containing these powders found to be improved, when compared with corresponding mixes without the powder additives.
