Details of these various types of concrete, their properties and applications are discussed. Contents:23 Types of Concrete and Their Applications1. Normal Strength Concrete2. Plain

Rate of Development of Strength This is generally faster in GPCCs, as compared to CCs. Reinforced GPCC Beams Load carrying capacity of GPCC beams, are up to about 20% more of CC beams at similar concrete strength levels. Cracking of concrete occurs whenever the tensile strength of the concrete is exceeded.

This is the first Chapter of the Book released by Oxford University Press, New Delhi, recently. Design of Reinforced Concrete Structures is designed to meet the requirements of undergraduate students of civil and structural engineering. This book

• It helps in determining the rate of gain of strength of concrete samples if cubes from the samples are crushed at different periods of time. • The variations in the results obtained at the site, from time to time for a particular grade of concrete can help in determining the quality control exercised and uniformity of concrete produced.

Solar Evaporation MethodThis is the oldest method of salt production. It has been used since salt crystals were first noticed in trapped pools of sea water. Its use is practical only in warm climates where the evaporation rate exceeds the precipitation rate, either annually or for extended periods, and ideally, where there are steady prevailing
