Use of Recycled Aggregates in Construction
Crushed sound and clean waste concrete of at least 95% by weight of concrete with typical total contamination lower than 1% of the bulk mass. Class 1A RCA is a well graded RCA with no more than 0.5% brick content. Partial replacement (30%) for natural aggregate in concrete for sidewalks, kerbs and gutters. Also for structural concrete (with mix

limitations of crushed concrete
Crushed recycled concrete can sometimes be used as the dry aggregate for brand new concrete if it is free of contaminants, though the use of recycled concrete limits strength and is not allowed in many jurisdictions.

Aggregate Crushing Value Test
Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate used in road construction is expressed by numerical index.

Methods of Limiting Temperature of Concrete
The common practice is to limit the temperature difference between the external concrete surface and the core to Celsius 20. However, in some projects, this value is kept at Celsius 25 considering the scale and type of concrete to be used. Further, the temperature gradient is not allowed to exceed Celsius 25 per linear meter.

Strength, Water Absorption and Porosity of Concrete
Results also indicate that the natural aggregate concrete has less compressive strength, less porosity and higher water absorption compared to that of concrete made with crushed aggregate. This is true for 0.4, 0.45, 0.5, and 0.55 water cement ratios.
