Study geotechnical properties for deposits in Dabas region ∕northwest Kirkuk for purpose brick manufacturing

Abstract

In view of the need of Kirkuk Governorate to manufacture bricks from clays, this study relied on the clays of the Anjanah Formation in the Dibs area to study the ability of these clays from a physical point of view to produce building bricks. The granular volume of the models consists mainly of granules of the sizes of clay and silt, and a small percentage of the sizes of sand, which is a silty clay soil, as it showed an increase in the percentage of clay over the components of silt and sand in the studied models, as the percentage of clay reached (49.75%), silt at a rate of (42.5%) and sand (7.75%), The results were classified according to Picard's chart, showing that it is located within the clayey silt field, and this indicates an increase in the ability to form the prepared dough for making bricks. And the results of the specific weight ranged between (2.71 -2.75) at a rate of (2.73). It was projected on the plasticity diagram, where the data of the results of this study showed the validity of these clays in the brick industry.
