●INTRODUCTION 

    NFJ metal aggregate is a new generation of construction material after steel fiber. The material is of hard metals, shaped like grain size. Its purpose is to strengthen the floor surface after the material is mixed with ordinary silicate and applied on the surface of concrete. It not only greatly increases the anti weariness of the concrete surface, but also improves the features of oil resistance, anti pressure, anti bending, tensile and impact resistance. Meanwhile it  causes no dust and helps to improve the working condition and environment, and it is the ideal concrete surface hardening material at present. 

    NFJ metal aggregate is with permanent anti corrosion after the composite anti corrosion treatment. It makes the construction work very easy and fine looking after curing. It features long endurance in the period of construction application. It has been technically authenticated and patented with Chinese Invention. Furthermore it is appraised by State Science Commission as A New Product of national level. It is also honored with many rewards such as silver and gold medals of China Patented New Product, and Science and Technology Improvement Award. The product enjoys the invention in China and tops all similar products in the world. Through ten years of study and development work, the product is formed up with a complete series from NFJ1 to NFJ6, so as to satisfy various demand.
