In _____________ floors, the brick arches or cement concrete arches are constructed and these arches rest on the lower flanges of mild steel joists. Correct Answer Jack arch

In Jack arch floors, the joists in turn raised either on wall around beam. The joists are placed at a distance of about 800 mm to 1200 mm Centre to centre. The rise of arches should be 100 mm to 200 mm and the minimum depth of concrete at the Crown should be 150 mm.

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.
