Preventing Cracks in Concrete with Steel Fibres

Concrete cracks can occur due to various factors such as shrinkage, temperature changes, and applied loads. Steel fibres help to control the formation and propagation of cracks in concrete. The fibres act as reinforcement, distributing the stress more evenly and reducing the width and length of cracks. Steel fibres improve the durability of concrete by reducing shrinkage and improving resistance to abrasion, impact, and fatigue. The fibres also help to prevent the development of microcracks and minimise the growth of existing cracks, thereby enhancing the overall resilience of the concrete.The selection of the right glass fibres product is based on its crack resistance, tensile, flexural, and compressive strength as per project requirements. STEWOLS INDIA (P) LTD. SHAKTIMAN® Steel Fibres can meet all these requirements.

The unique feature of SHAKTIMAN® Steel Fibres is its 3-dimensional reinforcements as compared to the 2-dimensional reinforcements of conventional steel reinforcement. The 3-dimensional reinforcements increase the tensile strength of the concrete at both the initial and ultimate crack under flexural loading. It can control even the tiniest of cracks and provide increased load-bearing capacity. It reduces repair and maintenance expenses by offering higher fatigue resistance.The product also minimises deformation while maximising durability.
