1. Comprehensive solution for non-waste processing of reinforced concrete constructions and scrap Comprehensive solution for non-waste processing of reinforced concrete constructions and scrap Russia 2016

2. MPR-1500 crusher for advanced non-waste processing MPR-1500 crusher represents an advanced technology on demolition waste processing to give a ready-to-use building material for building and road construction sectors. Processing line MPR-1500 for crushing and sorting pre-casts, bricks and concrete

3. Crushing & screening plant configuration The processing line may be of different configuration depending on client’s technical specifications and operation conditions and may include:  crushing unit(s)  sorting unit(s)  iron separator  conveyor system  control cab

4. MPR-1500 crusher for large-sized concrete  Capacity - 50 cubic m/hour (can be increased to 100 cu m/h)  Pre-casts’ maximum size is of 12.000х1.800х600mm  Power consumption 115kW/380V/50Hz  Metal inclusions and fittings are separated automatically  Crusher works in automatic mode  The whole operational process is managed by a single operator from the cab

5. End product Due to recycling of reinforced concrete and construction debris you get the secondary product of different dimensions:  Gravel of fractions: 1-10 / 5-10 / 10-20 / 20-40 mm  Sand of fractions: 0-0,16 / 0,16-5 mm  Stone flour: Ssp. = 2800-3500 cm2/g

6. Recycled and virgin aggregates testing Component W/C ratio Hardness, s Density, kg/m3 Compressive strength, MPa Recycled aggregates0,425241020,9 Natural aggregates0,415241521,0 As the results show there is an insignificant difference in strength characteristics between recycled and natural aggregates. It’s very reasonable to use recycled reinforced concrete as coarse aggregates for heavy-weightlow-grade concrete, as for example foundation blocks or for roads partial filling. It was agreed to take as samples cubic form stones with 10 cm edge. They were kept and tested in accordance with Russian State Standard 10180-90.

7. Recycled aggregates are used in following industries Graded crushed stone (gravel) Screened sand Manufacture of concrete and reinforced concrete Road construction industry Production of self- compacting concrete M 300-350 Stone flour (fog)

8. Areas of recycled aggregates utilization Fractions 10-70 mm:  As a coarse aggregate in producing Self-Compacting Concrete (SCC)  Producing Concrete Goods: foundation wall blocks, elements of storm water drain, storing wells, etc.  Soil stabilization: slope dressing, embankments, parking areas, etc.  Laying and repairing water supply and water disposal systems  In housebuilding as a foundation mattress  In roadbuilding Fractions 1-10 mm:  As a filler in foamed and gas concrete  Paving flagstone  Kerbs  Stair flights  Fences and crash barriers  Decorating elements  Landscape architecture  As earth replacement for backfilling (foundation pits, etc)
