Fire-Resistant Vermiculite Concrete Composites with Various Silica Components

Abstract

we present the results of studies of vermiculite concrete composites with various silica components such as cinder, tuff sand and volcanic ash for fire protection of building structures. The study shows that introduction of saponified wood resin into the vermiculite concrete mixture improves its rheological properties and reduces the average density of the composite. Portland cement can replace up to 20-25% of the mass of ash, tuff sand and cinder without significant deterioration of the properties of vermiculite concrete. Dispersed basalt fiber reinforcement of cement vermiculite concrete increases the strength and fire-resistant properties of the initial matrix.

Influence of reinforcement parameters on the properties of fibropenotoof concrete

“…To study the influence of the parameters of dispersed reinforcement on the properties of fibrofoam concrete, a composite rotatable plan of the second order of the type of a regular hexagon was used [1][2][3].…”

Fine-grained concrete with combined reinforcement by different types of fibers

“…In the case of distributed fibers their distribution in the matrix is more uniformly and short fibers tend to take random orientation. However, even in these systems, fiber distribution is rarely completely uniform, and random fiber orientation is far from ideal [16][17][18][19][20][21][22][23].…”

Phased evacuation algorithm for high–rise buildings

“…At present, there is a world trend in the high-rise construction development. Such buildings are subject to special requirements for ensuring fire safety, especially in terms of the construction material quality control and the organization of effective evacuation measures [1][2][3][4]. Particular attention is also paid to space-planning solutions [5], the flame effects on the structures operation [6][7][8][9] and the need for additional fire protection [10][11][12][13][14][15].…”
