Crack-resistant concrete macro fibers are widely used in municipal projects and private constructions due to their low cost and ease of application in the field of crack-resistant concrete.
Crack-resistant concrete macro fibers are specialized for use in crack-resistant concrete, with industry standards specifying fiber tensile strength between 270MPa and 400MPa. To meet market demands, our company utilizes recycled polypropylene granules and mature drawing processes to reduce the cost of crack-resistant concrete macro fibers, thereby maximizing cost savings for customers. Initially designed to replace transparent coarse fibers made from polypropylene raw materials to reduce costs, our crack-resistant concrete coarse fibers can perfectly substitute transparent polypropylene coarse fibers if the project does not have high requirements for fiber color. While ensuring fiber performance, our crack-resistant concrete macro fibers can save customers one-sixth of the project cost, ensuring both project quality and progress.
In practical applications, concrete macro fibers are increasingly used as alternatives to wire mesh and steel fibers to reduce the weight of structures. They are widely applied in municipal projects (including cement pipes, slope protection, cement guardrails, and cement covers and private constructions (including brick carvings, cement wall caps, cultured stone, and self-built houses with permanent formwork). Crack-resistant concrete macro fibers are easy to transport and handle, simple to construct with, and require minimal post-construction maintenance. The fibers’ surface features a threaded physical indentation, enhancing their grip within the concrete. When added to concrete, the fibers effectively suppress internal micro-crack formation during initial hardening, thereby improving the concrete’s resistance to large cracks over time, increasing its density, and enhancing its impermeability.
