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.
A construction company purchases cement at the rate of Rs. 1,000 per tonne and stores it at Rs. 100 per tonne. It is perceived that in the coming month, the price of cement will rise by Rs. 2,000 per tonne. The company already has 500 tonnes of cement. If the cement usage during a month is 1,000 tonnes, how much cement should the company purchase this month to minimize its expense in the next one?
