| description | The invention provides an ultra high performance concrete (UHPC) which comprises in parts by weight:
100 of Portland cement;
50 to 200 of a sand having a single grading with a D10 to D90 between 0.063 and 5mm, or a mixture of sands (preferably two sands), the finest sand having a D10 to D90 between 0.063 and 1mm and the coarsest sand having a D10 to D90 between 1 and 4mm
10 to 50 of a particulate substantially non-pozzolanic material having a mean particle size less than 15 ¼m;
0.1 to 10 of a water-reducing superplasticizer; and
10 to 30 of water;
which concrete is substantially free of silica fume;
the said concrete having a compressive strength greater than 100 Mpa at 28 days. |
