Durability of concrete

Dec 01, 2000· In our area, people are discussing the benefits or disadvantages of finishing exterior concrete containing ground granulated blast furnace (GGBF) slag. One group claims that since slag is finer than portland cement, a finisher brings more fines to the surface after straight edge and floating and thus creates a less durable surface. Another group suggests that the excess fines in a flatwork ...

In such situation, although rural concrete roads are supposed to be of M 30 grade, and the RCC slabs in houses are supposed to be of M 20 grade, the real scinario is terrible. With hand mixing of concrete, and with rodding of concrete in the formwork, no durable concrete can be produced. The result is shorter life - span of concrete structures.
