NO-FINE(R) CAR PARK

Although the structural and insulation properties of no-fines concrete have been used in housing construction and drainage, the material has potentially many other applications in civil engineering. Manufactured with a nominally single-size aggregate between 6-20 mm and an aggregate/cement ratio between 1:4 and 1:10, a no-fines concrete can have a 28-day cube strength of 7-20 n/sq mm. Offering a lower shrinkage and thermal coefficient than dense concrete, but with a high voids ratio, water can flow freely through it without any harm. Tests have shown that ice can expand within a no-fines concrete without doing any damage to the material. It is concluded that more use could be made of no-fines concrete as a free-draining surfacing for car parking areas and to enable the best waterproofing membranes to be used on multi-storey car park roofs. /TRRL/
