A device and method for improving the strength of cement or concrete

摘要

A method (fig.1) and device 8 is described for treating rubber particles with radiation. The method requires that the rubber be cleaned, and irradiated before being ready for incorporation with the remaining ingredients and cured to form the required composite. The device 8 is capable of rotating the rubber particles 10 whilst exposing them to radiation from a source 13, preferably electromagnetic radiation in the UV or UVC spectrum. The device ensures that the maximum amount of the surface area of the rubber particles is exposed to the radiation source as possible. Exposure of the rubber particles to the radiation source improves the bond strength between the rubber particle and the remaining ingredients that make up the matrix of the composite. Such composites may include cements and concretes.
