Construction Aggregates 101: What They Are (and Why They
Aggregates are raw materials that are produced from natural sources and extracted from pits and quarries, including gravel, crushed stone, and sand. When used Aggregate, in building and construction, material used for mixing with cement, bitumen, lime, gypsum, or other adhesive to form concrete or Aggregate Construction, Paving, Concrete

Vulnerability assessment of historical building aggregates in
The European building stock consists of a large number of unreinforced masonry structures. Masonry structures proved themselves to be fragile if subjected to horizontal loads, particularly out-of-plane. The complexity of existing structures during an earthquake increases if they are arranged in aggregates. This research deals with the That said, aggregates are quite literally the building blocks of our society. Aggregate production dates back to the Roman Empire, and it has been critical to the growth of our world ever since. Essentially, they are the most basic material used in construction. They provide the foundation for roads, bridges, and buildings, while alsoConstruction Aggregates 101: What They Are (and Why They

Comparative Seismic Assessment Methods for Masonry Building Aggregates
Recent seismic events produced considerable socio-economic losses. An important step for the reduction and mitigation of seismic risk in urban areas with a high population density is the assessment of global vulnerability of clustered buildings. The proposed work aims at appraising the seismic vulnerability of building aggregates within the historical center of This paper focuses on the unidirectional dynamic shake-table test performed on a prototype of a natural stone masonry building aggregate.

Geomaterials as construction aggregates: a state-of-the-art
Concerning the mode of utilization, aggregates are principally used either in a bound state (concrete) or unbound. Aggregates make essential part of the most widely used constructional material—concrete, which is vital for many other purposes in transport-infrastructural, commercial—and residential building, and other building projects.The benchmark here discussed relies on the seismic performance evaluation of two existing traditional masonry building aggregates located in the city of Sora, Central Italy [37], [38]. One of the most common typologies of masonry aggregates in Italian historical centers is the so called row housing typology, consisting of a series of structuralHistorical masonry building aggregates: advanced numerical insight

Seismic Testing of Adjacent Interacting Masonry Structures
In many historical centres in Europe, stone masonry buildings are part of building aggregates, which developed when the layout of the city or village was densified. In these aggregates, adjacent buildings share structural walls to support floors and roofs. Meanwhile, the masonry walls of the façades of adjacent buildings are often connected by dry joints The research on the masonry building aggregates after the L'Aquila and the Emilia-Romagna earthquakes demonstrated that the dynamic behavior of the buildings was influenced positively by the existence of adjacent structures despite their composition of low-quality material (Formisano, 2016).Frontiers Dynamic Behavior of Aggregated Buildings With
