Effect of Firing Temperatures on Physico - Mechanical Properties of Clay Bricks Containing Reeds

Ghazwan Abdulsamad Salman, Shakir Ahmed Salih


This research studies the effect of changing burning temperature on some properties of clay bricks containing reed crumbs. The experimental program includes production of clay bricks by adding (5-25) % by weight of reed crumbs to the clay before burning. The effect of addition of reed crumbs on properties of the produced brick such as dry density, Water absorption, and compressive strength were studied. Results of this research showed that it is possible to produced lightweight clay brick by adding (5-25) % of reed crumbs. Result also showed that a relatively good dry density and compressive strength could be obtained from the produce clay bricks made from addition of 5% reed crumbs. This type of brick led to save environment from huge amounts of agricultural wastes which its burning led to huge environmental pollution. It is discovered that, rising burning temperature from 800°C to 900°C and then to 1000°C causes a slight decrease in compressive strength and bulk densities values of the produced lightweight fired clay bricks containing reed. On the other hand rising burning temperature to the same degree as above causes a slight increase in the values of water absorption of the manufacture lightweight fired clay bricks containing reed. The laboratory experiments showed that lightweight fired clay bricks containing reed crumbs could be manufacture in the same factories of production of ordinary bricks without need to new machines. The steps of manufacturing this kind of bricks were found in this research the same for the ordinary one. The process of manufacture of lightweight clay bricks containing reed showed economical method of producing this kind of bricks.
