Cement Standards and Concrete Standards. ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.These ingredients are mixed with water to create concrete which is used as a primary construction material in buildings.These cement and concrete standards allow laboratories all over the world to test and evaluate concrete mixtures to ensure their strength and safety.hese ingredients are mixed with water to create concrete which is used as a primary construction material in buildings.

Page 2 of 10. The topic of Damascus steel is something that has been on the minds of metallurgists. for centuries. They have exceptional toughness and ability to hold a cutting edge (wear. resistance), which made them ideal for swords. They also had a characteristic pattern on the. surface, known as a âDamask patternâ [1].
Damascus is situated (33 degrees 30' North latitude, 36 degrees 18' East longitude) in the Northwest corner of the Ghuta, a fertile plain about 2,300 ft. above sea level, West of Mt. Hermon.The part of the Ghuta East of the city is called el-Merj, the meadow-land of Damascus.The river Barada (see ASANA) flows through Damascus and waters the plain, through which the Nahr el-Awaj (see PHARPAR) also flows, a few miles South of the city.amascus lies along the main stream of the Barada, almost entirely on its south bank. The city is about a mile long (East to West) and about half a mile broad (North to South).
