In a rating quarterly compiled by Russian Focus, Katavsky Cement tops the list of leading construction companies by production growth rates.  In the first five months of this year, Katavsky Cement, the oldest cement factory in South Urals, produced more than 191,000t of cement, boosting its output by 450 per cent year-on-year. By comparison, the output for the whole of last year stood at 142,000t.  The magazine points out that after Eurocement holding company affiliates took over late last year, the factory’s production, which had been standing idle since last October, gradually began its upward movement.
