Correlation Between the Properties of Iraqi Juss

Abstract

Due to the regular availability of raw materials, local juss is regarded as the primary and significant building material in Iraq (Gypsum). Gypsum has been regarded as a renowned metal since the time of Assyrian and Egyptian. Gypsum was used by the Greeks and Romans to make statues and was also used by the Egyptians to build the pyramids. Juss was considered a bonding material because it is not resistant to water action. Juss appearance is inseparable and synchronous with the appearance of bricks. This study mechanically and physically tested the compressive strength, consistency, setting time, and fineness of the local Juss specimen from Iraq. Every examination result achieved satisfies the Iraqi Juss standard requirements. The specimen under examination has the greatest compressive strength of 11.182 MPa, consistency of 40%, fineness of 1.9%, and setting time of 11.5 minutes.
