POLYMERIC MACROFIBER is a structural synthetic macrofibre intended for bulk reinforcement of concrete. Macrofiber is a modern alternative to steel mesh. Macrofiber is a structural synthetic macrofibre intended to improve the physical and mechanical properties of concrete and shotcrete. Macrofibre is a monofilament with a profiled surface to achieve the best adhesion to concrete and made of a special mixture of polymers. Due to the combination of a large amount of fiber fibers per kilogram of weight, their shape and ability to bond, a significant increase in the strength of concrete and sprayed concrete is achieved.
Macrofiber contributes to the increase in the strength limit for bending, plasticity, fatigue strength and impact resistance of concrete, are resistant to corrosive environments - alkali-resistant and acid-resistant.
We offer for delivery a certified macrofibre according to EN 14889-2: 2006 from 200 kg. (consists of packs of 1.0 kg.) The proposed price from the warehouse of Dnipro - 95,0 UAH. for 1 kg. with VAT, with such technical characteristics:
length of 25mm, 40mm;
-Diam. 0.6 / 1.0 mm,
- tensile strength - 400 MPa,
-module of elasticity - 6500 MPa,
-high resistance to acids and alkalis, low electrical conductivity, temp. melting point is 176 ° C.
The fiber enters directly into the mixer at the production site (stationary mixer or installed on the car). Fibers, together with cement, aggregate, sand and partially gravel, are simultaneously fed to the conveyor belt prior to the addition of water. Do not add the fibers the very first.
When all elements are added, mix at least 5 minutes. at the maximum speed. If the floor is further covered with a synthetic resin coating (topping) and the fibers can appear on the surface, they must first be burned using a burner using a flame.
The recommended consumption in industrial floors, screeds is 2.7-4.7 kg per m3 of concrete.
