"Investigation Some Properties of Recycled Reactive Powder Concrete containing Waste Materials"
The purpose of this research is to study some properties of effective powder concrete containing local waste (recycled aggregate) in different proportions (20%, 40%, 60%, 80%) as a partial substitute for regular fine aggregate and super soft glass waste powder in different proportions (10). %, 20%, 30%) As a partial alternative to the silica fume condensate these properties include: operability, density in the fresh state, compression resistance, direct tension resistance, bending resistance, total absorption, density in the rigid state and dehydration contraction.
The results showed that the use of recycled fine aggregate with a small percentage leads to a very small decrease in resistance while the high percentages of recycled fine aggregate led to a very clear decrease in resistance so the best percentage was 40% of the soft recycled aggregate
And it is possible to produce effective powder concrete with compression resistance (140.31 MPA) bending resistance (27.94 MPA and direct tensile resistance (13.21 MPA) at the age of 28 days.
