High-strength concrete is specified where reduced weight is important or where architectural considerations call for small support elements. By carrying loads more efficiently than normal-strength concrete, high-strength concrete also reduces the total amount of material placed and lowers the overall cost of the structure. The most common use of high-strength concrete is …
Prestressed concrete is composed of high-strength concrete and high-strength steel. Because of the high strength of these two materials, the resulting structures use much less concrete and steel and are, therefore, more economical. Concrete is an economical material for carrying compressive stresses, but has a very low tensile strength. In a prestressed concrete …
The new test data also includes recent research on steel tubes infilled with ultra-high strength concrete with cylinder compressive strength greater than 90 N/mm 2. The test results are used for comparison with the resistance predicted by EC4 (EN 1994–1–1, 2004) to establish the design guide of using high strength materials for CFST columns. In this database, test specimens …

It can have high strength, low absorption, good resistance to weathering, and resistance to some forms of chemical attack. Many of the physical properties of sound shotcrete are comparable or superior to those of conventional concrete or mortar having the same composition. Improperly applied shotcrete may create conditions much worse than the untreated condition. b. …
strength concrete, the use of high-strength concrete has increased rapidly in the last ten years and it is inevitable that it will come to be used in other areas of construc- tion in the near future. It is widely known that concrete becomes less deformable and more brittle when its compressive strength increases. Some previous tests [5] aimed to study axial and lateral strain with …

The compressive strength of concrete is measured by how much force is required to crush it, this is important in the design of structures. In pavements and other slabs on the ground, the design is usually based on flexural strength, (i.e.; how much force the concrete can withstand in bending before it breaks). In either case, the principal factors affecting strength are the water …
