Concrete strength. Many factors influence the rate at which the strength of concrete increases after mixing. Some of these are discussed below. First, though a couple of definitions may be useful: The processes of 'setting' and 'hardening' are often confused: Setting is the stiffening of the concrete after it has been placed. A concrete can be 'set' in that it is no longer fluid, but it may

Cost of concrete depends upon the following parameters. 1. Rate of materials (cement, sand, aggregate). 2. Brand of cement. 3. Grade of concrete. 4. Location (it's vary from city to city because rate of materials different in different states & ci

In the mid-1970s, researchers recognized that the "missing link" in the area of corrosion of steel in concrete was the inability to define rate of corrosion nondestructively. Con ventional methods of assessing condition put
