| Abstract | Waterproof concrete has reduced capillary water absorption properties as well as low permeability to water under pressure. Such qualities allow “waterproof” concrete to be used in water-resisting construction below ground in place of membranes, particularly where application of membranes is complicated by details and irregularities on the surface areas, thereby decreasing installation time and labour costs. In this paper a novel admixture to provide waterproof concrete is discussed. This waterproofing admixture provides added reduction in drying shrinkage to mitigate the development of cracks, thus eliminating a major concern with the concrete-only approach to waterproofing. In addition to enhanced resistance to cracking, concrete produced with the new admixture has excellent performance in the reduction of permeability and capillary absorption as well as good strength development [1]. Various laboratory test results and field projects mainly from Asian countries will be presented and discussed in this paper. |
