1. Cracks in the concrete Cracking is generally the first sign of distress in concrete. Cracking can occur in both hardened and fresh, plastic, concrete as a result of volume changes and repeated loading. The cracks make the concrete and the structure more vulnerable to external effects and can immediately reduce the mechanical resistance of the structure. Cracks reduce the ability […]
4 ways to tell it might be time to implement steel fibers in your concrete
Steel fibers or traditional rebar?
Are steel fibers better than rebar for industrial floor and external concrete paving applications, shotcrete and precast tunnel segments? Generally, fiber concrete is easy to work with and requires less labor force compared to rebar-reinforced concrete. It also saves time and space on site since there won’t be piles of mesh or reinforcement bars stored on-site and no time-consuming fabrication, […]
Steel fibers market
Steel fibers exhibit superior properties of tensile strength, shear strength, crack resistance, durability and corrosion resistance. Thus steel fibers are mainly used in reinforcement of the concrete to overcome the problem of concrete brittleness as well as to provide a better finish. The global steel fiber market is valued at USD 1732.5 million in 2019. The market size will reach […]
SPAJIC® certification
Dear readers, We hope you are all doing well. In today’s topic we would like to go over the new and updated certificates we have got for our products. Let’s begin with EN ISO 9001:2015 certificate. ISO 9001:2015 specifies requirements for a quality management system when an organization: – needs to demonstrate its ability to consistently provide products and services […]
Durability of steel fibers
The reduction of joints, the speed in the placement and the improvements in the performance in concrete have led to the inclusion of steel fibers in the various types of pavement, due to its qualities, a sufficiently proven and attractive solution for the industry. Unlike a commonly reinforced pavement, the pavement reinforced with steel fibers perform a three-dimensional reinforcement function. […]
Steel fibers with hooked ends – ZS/N
Steel fibers with hooked ends are filaments of steel wire (straight fibers with additional hooked ends) for reinforcement of concrete and mortar. For manufacturing steel fibers, we are using wires of different diameters deformed and cut to lengths.Steel fibers with hooked ends reinforcement is widely used as the main and unique reinforcing for industrial concrete floor slabs, shotcrete, prefabricated concrete […]
Advantages of the fiber reinforced concrete
SFRC is generally used to inhibit cracking, improve resistance of impact, to resist dynamic loading and material disintegration. SFRC can be used without any other additional reinforcement in almost all applications where flexural stresses are not overwhelming like beams for instance. Our steel fibers, especially ZS/5 with high performance which they provide are used in tunnel engineering, hydro structures, airport […]
SPAJIC Fortecrete150 – UHPC
Dear readers, we hope you will enjoy this blog post in which we are going to introduce our new product. What is UHPC you may ask? UHPC – Ultra-High Performance Concrete is a cementitious, concrete material that has a minimum specified compressive strength with specified durability, tensile ductility and toughness requirements; fibers are generally included in the mixture to achieve […]
Steel fibers performance in concrete
Dear readers, welcome to another post with a bit more details about concrete reinforced with steel fibers. Regarding the type of reinforcement used, concrete reinforced with steel fibers has become a fundamental material in the construction of industrial floors, pavements, bridge decks, elements for the stabilization of slopes, tunnel linings, precast structural elements, vaults and refractories, among others. When steel […]
Rebar Corrosion in Concrete
Welcome to our new blog post! In this post, we will cover the topic ”Rebar corrosion in Concrete”. Chloride induced corrosion to reinforcement is the leading cause of deterioration and degradation of concrete structures. Under conditions of wetting and drying concrete draws in and absorbs water, moisture and contained salts which affect reinforcement close to the surface and result in […]
