Aggregate & concrete production equipment

Aggregate is the main component of concrete which covers more than two-third parts by volume. Hence cost of the concrete is influenced by its aggregate. The strength of hardened concrete depends upon quality of its ingredients. Cement is the costliest ingredient in concrete and by using quality aggregate it can be economized.

Remediation of Acid Mine Drainage with Recycled …

A study was conducted to evaluate the efficacy of recycled concrete aggregate (RCA) and off-specification fly ash (FA) in remediating acid mine drainage (AMD).

What Are Aggregates and How Are They Used?

Using aggregate materials for concrete reduces production costs and increases the resistance of concrete mixes. Crushed aggregates make up for around 60% to 75% of the volume of concrete.

The Production of Sustainable Concrete with the Use of

The concrete industry is a core element of the building sector, but it has to deal with the increasing attention on the environmental issues related to the production process: increasing energy efficiency and the adoption of alternative fuels or raw materials represent the most relevant solutions. The present work analyses physical, mechanical, and environmental …
