Final answer:
Forms and shores should be removed after 24-48 hours, but it depends on various factors such as concrete type and weather conditions. It is crucial to follow recommendations from professionals or manufacturers for each specific project. The main goal is to ensure the concrete has gained enough strength.
Step-by-step explanation:
Forms and shores should not be removed as soon as the concrete is dry because concrete still needs time to gain adequate strength. The specific time for removing forms and shores varies depending on several factors such as the type of concrete used, weather conditions, and the size and design of the structure.
A general guideline is to remove forms and shores after 24-48 hours. However, it is crucial to follow the recommendations provided by engineers or concrete manufacturers for each specific project. These recommendations are based on testing and analysis to determine the optimal time for safe removal of forms and shores.
For example, in hot weather conditions, concrete may gain strength more quickly, allowing for earlier form and shore removal. On the other hand, in cold weather conditions, it may take longer for the concrete to reach the necessary strength, so extended curing times may be required. The main goal is to ensure that the concrete has gained enough strength to support its own weight and any additional loads it will encounter.
