Concrete Design & Production

Fine aggregate consists of natural sand, manufactured sand, or a combination thereof with particles that are typically smaller than 0.2 inches. Coarse aggregate consists of either (or a combination of) gravel, crushed gravel, crushed stone, air-cooled blast furnace slag, or crushed concrete, with particles generally larger than 0.2 inches.

Concrete Production an overview ScienceDirect Topics

Concrete production is a highly intensive energy-consuming process and presently facing a number of challenges in reducing the carbon footprint and making it more economic. Sustainable technologies in maintaining concrete structures are proving to be a great challenge. Microbially induced carbonate precipitation (MICP) has developed as a novel and sustainable technique in improving the

Abrasion and skid resistance of an aggregate are essential when the aggregate is to be used in concrete constantly subject to abrasion as in heavy-duty floors or pavements. Different minerals in the aggregate wear and polish at different rates. Harder aggregate can be selected in highly abrasive conditions to minimize wear.

Carbon Footprint of Recycled Aggregate Concrete

Aug 30, 2017· Five concrete mixes were produced with a water/cement ratio (w/c) of 0.5 and other five mixes with a w/c of 0.7. Five replacement rates of virgin coarse aggregate by recycled coarse aggregate (%R) were used: 0, 25, 50, 75, and 100%. OPC was used in all mixtures, and its production process was considered independently from the rest of the materials.
