الملخص EN

In this study, the characteristics of compressive resistance of ordinary and produced Iraqi cementwere studied in Umm Qasr laboratories1 The study was conducted using cubic cement forms1 All thesamples prepared for this purpose contain a fixed mixing ratio (1/3) (1 cement / 3 sand) (50) mm perrib and also "using cubic concrete forms and the length of the rib (150) mm and the rate of mixing(1 cement and 1.5 sand and 3 gravel), The study was carried out by adding the polypropylene fibersobtained from the waste collected from the electrical and electronic packaging belts1 The additivewas used in the form of fibers of length 15 cm and thickness (0.1, 0.2, 0.3, 0.4, 0.5 cm) in the mortarpaste starting from the model base and placed The measurements were based on the method oftreatment (dry, wet, water) as well as the number of polypropylene fibers added and five ratios anddifferent thickness of these fibers.

Also, Compression resistance of concrete with the same typeof the waste.

The best results were obtained when adding one fiber and a length of (15) cm and athickness of (014) cm in the case of dry treatment and at the age of seven days1
