摘要 |
<p>Lightweight concrete roof tiles are produced using a cement/lightweight aggregate/water mix containing a non-thixotropic silica fume in a weight ratio of silica fume (calculated as dry weight) to cement of about 2:98 to about 25:75, preferably about 8:92 to about 12:88. A dispersing agent for the silica fume is included in the mix. The presence of non-thixotropic silica fume in the mix enables lightweight roof tiles of adequate flexural strength to be produced. Novel roof tiles and novel cement/lightweight aggregate/water mixes for use in the method are also described.</p> |
