With the development of new cement-based raw materials, foaming agents and fillers used for special applications foam concrete, use concretes has become widespread. Foam concrete is a type that stands out with its lightness, waste potential, controlled low strength, thermal insulation, acoustics performance, durability. The knowledge base still developing this particular building material. This...

The performance requirements of the concrete of containment structures are mainly radiological protection, structural integrity and durability, etc. For this purpose, highperformance heavy density concrete with special attributes can be used. The aggregate of concrete plays an essential role in modifying concrete properties and the physico-mechanical properties of the concrete affect significan...

W characterize the equilibrium behavior in a broad class of competition models in which the competing firms’ market shares are given by an attraction model, and the aggregate sales in the industry depend on the aggregate attraction value according to a general function. Each firm’s revenues and costs are proportional with its expected sales volume, with a cost rate that depends on the firm’s ch...

Lightweight aggregate concrete (LWAC) is an increasingly important material for modern construction. However, although it has several advantages compared with conventional concrete, susceptible to segregation due the low density of incorporated aggregate. The phenomenon can adversely affect mechanical properties LWAC, reducing its compressive strength and durability. In this work, machine learn...
