The methods of disperse reinforcement of a concrete matrix with the help of fibers make it possible to manufacture structures of complex configuration and solve problems of frost resistance of products.Fiber replaces secondary reinforcement, reducing the volume of use of structural steel reinforcement.Cellular fibrous concrete is characterized by high performance properties, especially increased strength sukin body lotion woolworths in bending and stretching, impact strength and crack resistance.
As a reinforcing component, it is preferable to use mineral fibers or thin basalt fiber.The use of polyamide fiber is allowed, but there are difficulties in forming adhesive contacts between the fiber and the mineral matrix of cellular concrete.A feature of mineral fibers is that flex 4 heartworm test they are high adhesive to the cement matrix.
One of the promising types of dispersed bulk reinforcement of lightweight concrete is the use of expanded vermiculite.Expanded vermiculite can simultaneously be considered as a reinforcing component of a lamellar structure, as a component that reduces the density of the material and its thermal conductivity, as well as improves the fire protection performance.Expanded vermiculite can be used both in piece cladding products and as a part of dry warm and fire retardant plaster mixes.
