Cement manufacturing in Kenya


Cement manufacturing in Kenya is a vital industry that plays a crucial role in the country’s economic development. The Kenyan cement industry is dominated by four major players: Bamburi Cement, ARM Cement, East African Portland Cement Company (EAPCC), and Savannah Cement.

The manufacturing process of cement involves the extraction of raw materials, such as limestone, clay, and gypsum, from quarries and mines. These raw materials are crushed and ground into a fine powder. The powder is then heated in a kiln at very high temperatures, ranging from 1400 to 1500 degrees Celsius, which causes chemical reactions to take place, resulting in the formation of clinker.

The clinker is then cooled and ground into a fine powder, which is mixed with gypsum and other additives to produce different types of cement. The different types of cement produced include Portland cement, Pozzolana cement, and blended cement.

Cement manufacturing in Kenya is a significant contributor to the country’s Gross Domestic Product (GDP) and provides employment opportunities to thousands of Kenyans. The industry also plays a crucial role in the construction sector, as cement is a primary building material used in the construction of buildings, roads, bridges, and other infrastructure projects.
