Abstract:This paper describes the effect of various steam curing procedures on the compressive strength, tensile splitting strength, and modulus of elasticity of structural lightweight concrete. Particular emphasis is given to steaming proce-dures compatible with the time requirements of modern prestressing plants, and the investigation was patterned after asimilar investigation of normal weight concrete. In addition, a half-day curing cycle was studied. The investigation was restricted to a single lightweight aggregate without the inclusion of natural sand. The optimum conditions for steam curing of lightweight concrete were found to be little different from those for normal weight concrete. The allowable variation in the presteaming period was somewhat less. The reduction of potential strength development by steam curing was found to be less for lightweight concrete than for the normal weight material.
