On statistical characteristics of the compressive strength of recycled aggregate concrete J. Xiao, J. Li and Ch. Zhang This paper presents a statistical analysis of the compressive strength of recycled aggregate concrete (RAC) with recycled coarse aggregate (RCA) coming from one single source.

This study evaluated the use of recycled concrete as coarse aggregate in new concrete pavements. Recycled concrete aggregate (RCA) produced from demolished pavements in three geographically-dispersed locations in Washington state were used to perform testson aggregate characte ristics, fresh concrete propertiesand hardened concrete properties.

Recycled concrete aggregates produced from all but the poorest quality original concrete can be expected to pass the same tests required of conventional aggregates. Recycled concrete aggregates contain not only the original aggregates, but also hydrated cement paste.

This paper investigates the effect of recycled coarse aggregate incorporation on the relationship between 150 mm cubic and Փ 150 mm cylindrical compressive strength (the reference strength of standards) by comparing data from recycled and natural aggregate concrete compositions in which both cubes and cylinders were tested. A conversion factor from cubic to cylindrical strength is …

Study of recycled concrete aggregate quality and its relationship with recycled concrete compressive strength using database analysis • 3. Materiales de Construcción 66 (323), July–September 2016, e089.

The construction industry consumes enormous quantities of concrete, which subsequently produces large amount of material waste during production and demolishing. As a result, the colossal quantity of concrete rubble is disposed in landfills. This paper, therefore, evaluated the feasibility of reusing waste concrete as recycled aggregate (RA) to produce concrete.

This chapter has been prepared with the hope that its readers will become interested in lightweight concrete (LWC). Therefore, after a brief background of lightweight concrete, different types of LWC will be introduced and then LWC made of lightweight aggregates (LWA) will be specifically discussed. Compressive strength and density of LWC are the main points of interest in this chapter.

The ultimate strength of concrete is related to water/cement ratio and the size, shape, and strength of the aggregate used. Concrete with lower water/cement ratio (down to 0.35) makes a stronger concrete than a higher ratio. Concrete made with smooth pebbles is weaker than that made with rough-surfaced broken rock pieces for example.
