BS EN 206-1 defines High strength concrete as concrete with a compressive strength class higher than C50/60. High-strength concrete is made by lowering the water-cement (W/C) ratio to 0.35 or lower. Often silica fume is added to prevent the formation of free calcium hydroxide crystals in the cement ...The very high mass of concrete poured into the concrete maintains the stability of the structure against the gravity loads and the horizontal loads applied to them. Vertical as well as horizontal construction joints are provided in the structures of this nature due to the high volume of concrete to be poured.High –strength concrete is occasionally used in the construction of highway bridges.
