SUPERPLASTICISER EFFECT ON TIME-DEPENDENT PROPERTIES OF AIR ENTRAINED CONCRETE

Developed more than 15 years ago in Japan, and in commercial use in Germany since 1972, superplasticisers are stated as having considerable advantages over conventional plasticisers. In order to assess these benefits, a series of tests is reported, undertaken to investigate the long-term behaviour of concretes containing the superplasticiser irgament mighty 150, type: napthalene sulphonate/formaldehyde condensate. The time-dependent behaviour of strength, elasticity, durability, creep and shrinkage of high workability (flowing) admixture air entrained concretes are reported. Details of the mixes used in the tests are provided, and the experimental data are presented and the results discussed. (TRRL)
