摘要 |
<p>A material primarily for replacing asbestos-cement products includes a reinforcing network of continuous, fibrillated organic film and a water-hardened mass such as Portland cement and sand or alternatively gypsum. The organic film may be a polyolefin such as polypropylene or high modulus polyethylene. The reinforcement may be incorporated as a woven or non-woven network. A process for making such a material is also described. The material has, in some respects, superior properties in relation to those of asbestos-cement.</p> |
