essential ingredients of concrete are cement, aggregate (sand, gravel) and water. Concrete blocks are produced in a large variety of shapes and sizes. They can be produced manually or with the help of machines. Most commonly used concrete blocks are sized: Length: 40cm (half blocks: 20cm) Height: 20cm Width: 8/10/15/20cm
Hollow Concrete Blocks (HCBs) are manufactured by using coarse aggregate, fine aggregate, cement and water. We have made an attempt to replace conventional materials by concrete waste materials (CWMs) in the manufacture of HCBs. In this present work, we report the manufacture of HCBs by the replacement of coarse aggregates with 10% and …
It includes extraction of fine aggregate from construction and demolition wastes of hollow concrete block (HCB) found in Ethiopia, investigate physical and chemical properties of recycled fine aggregate. Finally, the replacement amount of river sand by recycled fine aggregate in the production of concrete was determined.
Three distinct types of hollow concrete blocks were produced to assess the effectiveness of such blocks in the market. In addition, the experimentally determined thermal resistance was used to calculate the expenses, oil consumption, and CO2 emissions.
In order to produce reinforced concrete and hollow concrete blocks with good quality which satisfy strength and durability requirements, great care have to be taken for their …
