organic content of construction aggregate

Aggregate Organic Constituents ScienceDirect

2017-1-1  As shown in Fig. 4.1, the main methods for the quantification of organic matter potentially considered as a pollution source are organic carbon content (TOC or DOC) and oxygen demands (BOD and COD).UV absorbance at 254 nm and SUVA (ratio of A254/DOC) are also used as surrogate parameters.These methods are standardised (), but UV spectrophotometry can give useful

Characterizing organic matter of soil aggregate

In some soils, aggregate coatings and walls of biopores differ in the content of clay and organic carbon from that of the aggregate interiors or the soil matrix. The composition of the organic matter on aggregates and on the surfaces of biopores is largely unknown.

The influence of organic matter on aggregate stability

The relationships between aggregate stability, and organic matter content plus some of its component fractions were examined in more detail using 120 soils. Total organic matter, total carbohydrate and humic material extracted by various reagents each gave highly or very highly significant correlations with aggregate stability.

Aggregate Nanostructures of Organic Molecular

2010-10-13  Conjugated organic molecules are interesting materials because of their structures and their electronic, electrical, magnetic, optical, biological, and chemical properties. However, researchers continue to face great challenges in the construction of well-defined organic compounds that aggregate into larger molecular materials such as nanowires, tubes, rods, particles, walls, films, and other

Changes of the organic carbon content and stability of

2018-12-1  Several studies reported that changes in plant composition due to afforestation could greatly influence soil properties, such as pH and organic input, thereby affecting TOC content and soil aggregate stability (Cavagnaro et al., 2016; Ren et al., 2016b). However, changes in TOC content and soil aggregate stability could also be attributed to

What are the Sources of Natural Aggregates?

2021-5-5  Aggregates are the most important constituents in concrete.They give body to the concrete, reduce shrinkage and effect economy. Natural aggregates are inert granular materials such as sand, gravel stone or crushed stone that are used with a binding medium i.e. water, bitumen, portland cement, lime, etc. to form compound materials i.e. asphalt concrete and portland cement concrete.
