Construction of crystalline homo/heteroaggregation at micro/nanometer level from organic π-conjugated systems is of great importance because the controllable morphologies (i.e., size, shape, and dimension) could provide diverse optoelectronic properties for different applications in the electrooptical devices.

amount of air, water, cement, and fine aggregate (that is, the mortar fraction) should be about 50% to 65% by absolute volume (45% to 60% by mass). Rounded aggre-gate, such as gravel, requires slightly lower values, while crushed aggregate requires slightly higher values. Fine aggregate content is usually 35% to 45% by mass or

Micro-texture refers to the small-scale texture of the aggregate surface, which controls the contact between the tire rubber and the pavement surface. Micro-texture is a function of aggregate particle mineralogy, petrology, and source (natural or manufactured), and is affected by the environmental effects and the action of traffic, .

Aggregate aims to publish on a wide variety of topics that focus on the processes of aggregation of atoms, ions, molecules, oligomers, polymers, clusters, particles, gels, hybrids, composites, cells, pathogens, etc. in a broad range of areas such as chemistry, physics, materials, engineering, biology, life science and so forth. Aggregates often behave differently from, and …

Nevertheless, there are several limitations of re-using of recycled concrete aggregate, for instance high porosity, high water absorption rate, micro cracks in the interfacial transition zones. Due to those limitations, the concrete produced with recycled aggregate has low properties than the concrete made with natural aggregates.

1.1 This classification defines aggregate size number desig-nations and standard size ranges for mechanical sieve analyses of coarse aggregate and screenings for use in the construction and maintenance of various types of highways and bridges. 1.2 Units—The values stated in SI units are to be regarded as standard.
