Aug , by analyzing concrete used to build ,yearold roman structures, a team of scientists may have found a longerlasting, greener alternative to modern cement in addition, the production
The materials required for the production of the concrete blocks are aggregates, cement and water the aggregates of various types have been used with varying degree of success and they include crushed stones, gravel, volcanic cinders, foamed slag, furnace clinker, etc
The production of concrete blocks consists of four basic processes mixing, molding, curing, and cubing some manufacturing plants produce only concrete blocks, while others may produce a wide variety of precast concrete products including blocks, flat paver stones, and decorative landscaping pieces such as lawn edging
