elements complement the hydration chemistry of cement. On hydration, cement produces C-S-H gel and free lime, i.e. Ca(OH)2. The C-S-H gel binds the aggregates together and strengthens the concrete. Water, sulphates and C02 present in the environment attack the free lime causing deterioration of the concrete. A cement technolo

Transport in Kyrgyzstan is severely constrained by the country's alpine topography. Roads have to snake up steep valleys, cross passes of 3,000 m (9,843 ft) altitude and more, and are subject to frequent mud slides and snow avalanches. Winter travel is close to impossible in many of the more remote and high-altitude regions.
