تقييم تأثير إضافة غبار الإسمنت على بعض خصائص الإسمنت البورتلاندي

Abstract EN

The cement industry is one of the biggest and most strategic industries in Libya and so as in many other countries around the world.

Many of those countries pay great attention to national prosperity and economic growth, yet make jobs available to people.

However, such industries and so as many others have negative sides, particularly in regard to the environment.

These industries generate emissions such as gases and particles as extraneous products of the cement production process of which the so-called cement dust (CD) is most important.

To take advantage of this extraneous product and to achieve environmental and economic benefit, this study investigates the possibility of CD recycling and blending at (2, 4, 6, & 8) wt.% with Portland Cement, and investigates some tests such as initial and final setting times tests, compressive strength test, expansion test.

The final results proved that blending (6 wt.%) was most appreciable as fitted with the Libyan standard specifications.
