1. Ultra High Performance Concrete (UHPC)

2. UHPC
It is a high strength, ductile material formulated by combining of cement, silica fume, quartz silica sand , crushed quartz, super plasticizer and metallic fibers

3. Ductile Mix Design No coarse aggregate Cement 710 kg/m3 Silica Fume
Crushed Quartz
Sand
Fibres
Plasticiser
Total Water
No coarse aggregate

4. MATERIALS SIZE Quarts silica sand 0.3 – 0.8mm was used as aggregate.
Cement 1 to 250 micron
Silica fume 0.1 – 1.0 micron

5. Metallic fiber dia 0.18 – 0.25, length 6 – 20mm and 2500 tensile strength

7. Comparing Properties Properties of UHPC
Compressive strengths up to 200 Mpa
Flexural Strengths up to 50 Mpa
Direct tension up to 10 Mpa
Properties of Concrete
