1 Lab Manual of Concrete Technology

The fineness of cement has an important bearing on the rate of hydration and hence on the rate of gain of strength and also on the rate of evolution of heat. Finer cement offers a greater surface area for hydration and hence faster the development of strength, (Fig. 3). The fineness of grinding has increased over the years.


Cement & Concrete Hazards In Construction

Concrete Burns • Sand contained in fresh concrete is abrasive to bare skin • Portland is an alkaline. Strong bases (ph of 12-13) are just as hazardous as strong acids to the skin but have no initial signs of pain such as a burning sensation. • Drying Portland is hygroscopic – it absorbs water. Portland needs water to harden.
