Properties of Self-Consolidating Concrete Produced Using Local Algerian Materials Nasr-eddine Bouhamou2, Nadia Belas2, Ahmed Attar1, Belkacem Achour2 and Abdelkader Mebrouki2 Abstract This paper describes an experimental investigation of the effects of the WaterCement ratio on the behaviour of self-consolidating concrete
Aggregates. Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the ...
Reading time 1 minuteCrushed concrete aggregates also called as recycled concrete aggregates are fragments and pieces of concrete buildings which are demolished or rebuild. These crushed concrete are cleaned from dirt and broken to smaller pieces to manufacture aggregate which is termed as recycled aggregate. Crushed concrete aggregate eliminates the need for disposal by
Aggregates are also used in agriculture, manufacturing, and other industries. An indispensable ingredient . Aggregates are an indispensable ingredient in ready-mix concrete, asphalt, and mortar. Accounting for approximately 60 to 75 of ready-mix concretes volume, aggregates strongly influence concretes freshly mixed and hardened properties.
Fig 1 Aggregates used in production of concrete. The aggregates are broadly classified into two types based on the size, namely- fine aggregate and coarse aggregate. In this article, we discuss the properties of the standard aggregates used in the production of concrete as per the American Standards ASTM- C33C33M.
Quality Counts. Make sure that your concrete producer purchases good-quality aggregate as verified by regular aggregate test results in compliance with ASTM C 33, Standard Specifications for Concrete Aggregates. A history of good performance of a local aggregate also provides an indication of how well the material performs in service.
