WebConcrete can be kept moist (and in some cases at a favor- able temperature) by three curing methods: 1. Methods that maintain the presence of mixing water in the concrete during the early hardening period. These include ponding or immersion, spraying or fogging, and saturated wet coverings. WebConcrete curing techniques fall into two groups - those designed to prevent loss of water, such as the application of impermeable membranes; and those that supply moisture throughout the early stages of the hydration process, such as ponding or the application of wet sand or hessian. WebFor the majority of structures, the curing time at temperatures above 5º C (40º F) should be at least 7 days or until 70% of the specified compressive or flexural strength is attained, whichever is longer. The curing period can be reduced to 3 days if high early strength concrete is used and the temperature is above 10º C (50º F ... craft machines silhouette
