STRONGER, BIGGER, BETTER

This article examines the construction and testing of the largest high-strength concrete slab ever produced in the UK. A 15m x 15m high-strength concrete slab, with a depth of only 250mm, was designed by Ove Arup and Partners, and constructed at Taywood Engineering's Technology Centre. The slab is supported on four 300mm x 300mm columns, 9m apart. It incorporates the results of extensive research into new designs for reinforcement in high-strength concrete structures. Its test programme is intended to validate the new design rules, and produce further experience with construction using high-strength concrete. Experience shows that such concrete may reduce costs and produce significant design, construction, and maintenance benefits. The Grade C110 high-strength microsilica concrete for the slab developed its in-situ strength very rapidly. The test slab was loaded to a uniform 1.5kN/sq m plus dead load at three days, to simulate typical construction loads. The load was maintained for ten days, but very little creep was observed. 28 days after casting, the slab was loaded to 13.125kN/sq m including dead load, to examine its performance at serviceability loads. The test results show that it is very practical for the UK construction industry to use high-strength concrete on site.
