دراسة تجريبية مقارنة لتأثير الإضافات الصناعية في مقاومات البيتون

الملخص EN

There are various types of industrial fibers such as: (polypropylene fiber, fiberglass, silica fume powder, etc..).

These fibers are used widely as additives for improving concrete strength.

We study in our research the effect of each of polypropylene fibers, steel fibers, and silica fume powder, on two kinds of concrete mix the first ordinary mix and the second is mix other with Mazar sand.

We found after the studying of mechanical properties for those mixes that a slight improvement on tensile strength of concrete has occurred, an increasing of compression strength of concrete has happened, and the failure style has changed according to the type of additive compared with concrete without additive.
