Yamama (Named so by Founders after the historical name of Riyadh area) Cement Company (YCC) is a Saudi shareholding company ranks among the biggest cement producers in the country and one of the pioneers as well. It was founded in 1961 in Riyadh city by H.H. late prince Mohammad Bin Saud Al-Kabir with a capital of SR 25 Million. YCC produces and sells cement to satisfy the country`s need for this strategic material and to initiate heavy industries that utilize local raw materials. Government support combined with wise management decisions played a great role in encouraging Yamama to expand its factory and add new production lines. The production started in 1966 with a humble 300 t/d line. The first extension was as early as 1972 when a line of 800 t/ds was added to raise the total annual production up to 330 thousand TPA (Tons Per Annum). The big jump came six years later in 1978 when two production lines were added 1500 t/d each, thus raising the total capacity up to 1.23 million TPA of clinker. Having four kilns, so far, was not enough to coup with the enormous increase in demand, therefore a fifth kiln was added in (1982) to make the designed capacity go as high as 1.68 million TPA. In 1985 a fourth extension added a 3000 t/d preheating (precalcining) short kiln, abandoning thus, for good, the older technology of long dry kilns. In fact Yamama`s development in designed capacity was accompanied by other developments in manpower, capital, realized profits, management organization and services which made a giant out of that small company born 40 years ago. Yamama Cement produces two types of cement conforming to both local and international standards. Besides the most commonly used Ordinary Portland Cement (OPC or type1).Yamama produces also the Sulfate Resistant Cement (SRC or type 5). It has the capability to produce any other type on demand especially for orders with sufficient quantities. It produces also the paper sacks needed for packing its cement. For this purpose it has its own sacks factory, which produces 30 million sacks per year per one shift.
