| 摘要 |
<p>The present invention relates to a light weight and permeable construction material and a process for the manufacture thereof by mixing cement, rubber aggregate, silicate based aggregated (gravely) and water. When cured, the rubber and silicate aggregates are bonded together in a porous and permeable matrix by the cementitious material. In addition, it is preferred that polymer fibres and/or rubber powder derived from waste rubber tyres is added to material and acts as an elastic binding material which improves the physical properties of the constructional material. Depending on the particular engineering application, material can be cast-in-place or formed into precast blocks.</p> |
