MIKROGRANULÄRE BETONZUSAMMENSETZUNG MIT METALLISCHEN VERSTÄRKUNGSFASERN |
摘要 |
<p>The invention concerns a microgranular concrete composition based on slag cement, comprising 100 parts by weight (p) of slag cement; 15 p to 50 p of micro-elements with pozzolanic properties having a grain size between 0.1 and 1 mu m, preferably between 0.1 and 0.5 mu m; 10 p to 50 p of microelements with hydraulic properties having a D50 ranging between 2 and 10 mu m, and a maximum grain size of 40 mu m, preferably 30 mu m; 90 p to 210 p of sand having a D50 ranging between 100 and 500 mu m; and a maximum grain size not more than 1000 mu m; 10 p to 40 p, preferably 20 p, of water; and 0.5 p to 5 p (dry extract) of a dispersing or fluidizing agent, the constituents other than water being slag in a proportion of 50 to 90 wt.% of said constituents. The composition can further contain metal fibres of different dimensions.</p> |
