Concrete has the unique distinction of being the only construction material manufactured on the site. A concrete mixer machine is a device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete. A typical concrete machine mixer uses a revolving drum to mix the components. These machines are too expensive and because of these small scale construction workers use traditional method of mixing concrete. This method of manual mixing takes a lot of time to produce a mixture and also requires large human effort to mix it.

Environmental and Biosystems Engineering  students participated in tree planting event at Ngong forest on Saturday, 23rd April, 2022. The event was organized by Engineering Students Association (ESA) from Faculty of Engineering.

The environmental goal was to explore real-world problems and become a community of environmentally-minded thinkers. By planting more trees, it will contribute to global reforestation efforts, repairing damaged ecosystems and mitigating climate changes.
