The socio-political significance of changes to the vocational education system in Germany

This paper explores the effects on social inequality in Germany of ongoing changes to the employment system and, thus, vocational education. Results based on an examination of the literature indicate that students from increasingly middleclass backgrounds with higher levels of general, rather than vocational, educational attainment are winning the competition for ever-fewer apprenticeships. Progress for women in education is accompanied by relative declines in men’s performance on high school exit examinations and does not translate into success in the employment system. Employers are abandoning the corporate-state organization of vocational education. The paper concludes that school degrees are increasingly important for later career opportunities. As a result, the educational system is increasingly stratified, contributing to social inequality in Germany

Fixing of chloride in concrete using admixtures

In the present investigation a method to reduce chloride in concrete has been attempted by using aluminium oxide as a chemical admixture. Studies were conducted with different amounts of admixture, namely 5 percent, 10 percent and 15 percent by weight of cement. It was concluded that aluminium oxide may effectively reduce the free chloride content in concrete and thereby reduce the risk of reinforced corrosio
