II. Materials and Methodology The concrete waste materials were collected from the construction sites at Adama, Oromia region, Ethiopia. A total number of 90 samples were casted to get the HCBs. The concrete waste material was crushed into smaller size and subjected to sun drying for 48 hrs.
This way glass, wood, asbestos, metals, plastics, hazardous materials, etc. can be separated, obtaining the majority of the inert waste fraction, comprising mainly concrete and masonry remains [21], [23]. Such waste materials can be readily processed into Recycled Aggregates (RA) for use in place of Natural Aggregates (NA).
This publication covers the materials used in concrete and the essentials required to design and control concrete mixtures for a wide variety of structures. Figure 1-1. Concrete components: cement, water, coarse aggregate, fine aggregate, supplementary cementing materials, and chemical admixtures. Figure 1-2.
3D concrete is a new and advanced manufacturing paradigm for the construction industry. While the technology is still more expensive than the traditional building fabrication method, the additive manufacturing …
3.3 Ground Granulated Blast Furnace Slag (GGBFS) It is a special type of industrial waste that is obtained from industries where scrap iron is used for the production of steel. This waste normally falls under the category of mineral admixture, which is added to the cement to influence the properties of concrete.
