Abstract:The construction procedure of a nuclear containment concrete structure recently built required a highly workable concrete to facilitate placing around heavily congested steel embedments and reinforcements. Use of a superplasticizing admixture was considered essential. A test program was undertaken with several commercially available admixtures to study the properties of the fresh and hardened concrete made with low-heat cement (CSA: A5 Type 40). Under controlled conditions, four of these products met the construction requirements without adversely affecting the properties of the concrete.
