Rubberized concrete is formed and solidified by mixing rubber particles, rubber powder, rubber emulsion and auxiliary admixtures with cement when preparing cement mortar or concrete. Also known as elastic concrete and colloidal concrete.
Based on the consideration of improving the mechanical properties of concrete, modifiers such as rubber are added to the concrete. Adding waste tires and other rubber particles into concrete can reduce the weight of the concrete itself and improve the deformation capacity of the concrete.
Chopping and grinding waste tires into concrete to make rubberized concrete is increasingly becoming a new direction of concrete application.
After the addition of rubber particles, the compressive and tensile strength properties of the concrete decrease, but the ductility increases, which makes the concrete have better impact resistance and reduces the development of concrete cracks.
Rubberized concrete is modified with rubber to provide better freeze-thaw and erosion resistance and increased durability.
Cement concrete modified with waste rubber has excellent elastic and plastic properties, noise absorption, heavy pressure resistance, not easy to wear, good impact resistance, and good durability. Therefore, the application of rubber-modified concrete in road pavement construction not only has the advantages of asphalt pavement, but also has much higher durability than asphalt pavement, so it has obvious advantages.
