Organic Content Of Construction Aggregate

Characterization of recycled aggregates construction and ...

2011-2-1  Organic matter contentOrganic matter content is harmful to concrete in that it alters its setting and hardening, and thus decreases its adhesion. This leads to problems of low-resistance and durability. According to the EHE-08, the aggregate used in structural concrete should not contain organic matter.

Hence, the classification of a J-aggregate solely based on the observed red-shift can be misleading. Instead, the change of the vibronic pattern, i.e., an increase of the ratio of the intensities of the 0−0 and 0−1 bands can often be used as a reliable criterion for the classification of a classic J-aggregate. 3 Organic Solar Cells
