A binder, or substance that sets, hardens, and adheres to other materials to bind them together, is what construction workers refer to as cement. Cement is typically used to bind sand and gravel (aggregate) rather than on its own. Concrete is made by mixing cement with sand, gravel, and fine aggregate to create mortar for brickwork.
The most utilised substance in existence and the second most consumed resource on Earth is concrete.The majority of cements used in construction are inorganic, frequently lime- or calcium-silicate-based, and can be classified as hydraulic or non-hydraulic depending on their propensity to set in the presence of water (see hydraulic and non-hydraulic lime plaster).
A chemical interaction between the dry materials and the water causes hydraulic cements, such as Portland cement, to set and become adhesive. Mineral hydrates are created as a result of the chemical reaction, which are resistant to chemical attack and not particularly water soluble.
In addition to protecting the hardened material against chemical assault, this enables setting in damp environments or under water. Ancient Romans who utilised volcanic ash (pozzolana) with additional lime discovered the chemical procedure for hydraulic cement (calcium oxide).In wet or submerged environments, non-hydraulic cement (least popular) is not set. Instead, it dries and sets as it reacts with the air’s carbon dioxide. Once it has been set, it is resistant to chemical attack.
The Ethiopia Cement market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Over the past years, Ethiopia’s cement sector has experienced significant expansion. However, issues related to the government’s investment policy could reverse these achievements. Ethiopia is one of the leading cement producers in sub-Saharan Africa, with a capacity of tonnes of cement and an average annual consumption growth . It is rivalled only by South Africa and Nigeria.
In these years Ethiopia saw a surge in cement consumption as a result of the government’s significant investments in transportation, infrastructure, and other areas. Projects include building new railway connections such as the Awash-Kombolcha-Hara-Gebeya, the Mekelle-Hara-Gebeya, and the Addis Ababa-Djibouti.The building of the Great Ethiopian Renaissance Dam, as well as the Gilgel-Gibe III and Genale Dawa hydropower dams, have all attracted significant public investment.
