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.
