Analysis of total chloride content in concrete

Total chloride content:is the total amount of chloride ion in a sample of concrete, including bound in the solid phases and free chlorides in the pore solution. Free chloride content:is the amount of chloride ion in the pore solution as obtained by squeezing con-crete samples at high pressures.

Wadi gravel – a new concrete aggregate in Qatar: .

In hot desert regions, attention is turning to local sources of aggregate that were previously regarded as 'too difficult' to exploit. This paper describes an investigation of such a deposit in Qatar. The material, known as Wadi gravel, is a gravelly sand of Tertiary age cemented by gypsum. A field survey found the gravel content to be in the range of 10 to 20%.
