Abstract

This paper describes an experimental investigation of the behaviour of self-consolidating concrete (SCC) produced under conditions of hot weather studied in the context of manufacturing control specimens. Two different designs were tested, incorporating either OPC or slag cement. The spread, determined during the slump–flow test, was kept constant whatever the initial temperature (20 or 50 °C), either by additions of water or by superplasticizer over dosage at the end of mixing. L-box and sieve stability tests were also employed to assess the self-consolidating ability. Specimens were cured under the conditions specified in the standards for manufacturing control (20 °C, 100 % RH). Compressive strength, bulk modulus of elasticity, porosity, water absorption, migration of chloride ion and gas permeability were quantified. Results on SCC mixed at high temperature (50 °C) relative to results for the reference mixes (20 °C) showed that mechanical and physical properties were not altered or improved by the increased mix temperature.
