The importance of using high strength concrete and high tensile steel was introduced by ___________ Correct Answer Freyssinet

Freyssinet in 1928-1933 has given the importance of using high strength concrete and steel in order to various losses of prestress due to creep and shrinkage and he also developed vibration technique to produce high strength concrete also manufactured double acting jack for stressing high tensile steel wires into the concrete structure.

Permeability in concrete is studied towards providing for, or guarding against, which of the following features? 1. The penetration by materials in solution may adversely affect the durability of concrete; moreover, aggressive liquids 'attack' the concrete. 2. In the case of reinforced concrete, ingress of moisture and air will result in corrosion of steel leading to an increase in the volume of steel, resulting in cracking and swilling of the concrete cover. 3. The moisture penetration depends on permeability and if the concrete can become saturated with water it is less vulnerable to frost action.
