Products and Services
Diamond Cement is one of the world’s largest building materials companies and operates on five continents. Our products are used for the construction of houses, infrastructure, commercial and industrial facilities, thus meeting the demands of a growing world population for housing and economic development.
Our core activities include the production and distribution of cement and aggregates . Furthermore, Diamond Cement Group offers services such as trading in major African countries.
Cement
Cement is a finely milled mineral powder, usually grey in colour. The most important raw materials for the production of cement are limestone, clay, and marl. Mixed with water, cement serves as an adhesive to bind sand, gravel, and hard rock in concrete. Cement hardens both in the air and under water, and remains in its hardened state once reached.
Cement is usually available in the form of a homogeneous bulk dry good. It’s characteristics are standardised in order to ensure the required stability, reliability, and processability in the application.
Cements are classified according to their early and final strength as well as their composition. In addition to cements that consist of clinker, there are so-called composite cements, in which a portion of the clinker is replaced by alternative raw materials, such as fly ash, ground slag, or limestone. As the production of clinker is energy-intensive and releases large amounts of CO2, the use of alternative raw materials can conserve natural resources and reduce CO2 emissions.
Research and Development
The aim of research and development (R&D) at Diamond Cement is to develop innovative products as well as process improvements and new formulations, in order to minimise the use of energy and CO2 emissions.
Our Research and Development Activities
The innovation work at Diamond Cementt can essentially be divided into five areas of focus:
Products and Applications
The main priority is the development and improvement of binders and concretes with optimised properties and innovative functionalities. In 2020, we focused on reducing CO2 emissions by analysing the life cycle of concrete. Improving the characteristics of cement and concrete is an important lever in terms of both optimising the use of these building materials and reducing the overall CO2 emissions associated with concrete use.
