How Long Should Concrete Dry Before Removing Forms

Concrete continues to cure for seven days after it has been poured into the forms, so the total curing time is up to 21 days. After this time, the concrete slab needs to reach its full strength before it can be used. Slabs that are cast in hot climates will dry out faster than those cast in cold climates. Moisture levels also affect the curing

What affects screed drying time? The Screed Scientist

2022-4-30 · For sand and cement expect 1mm a day drying time for floors of 1-50mm thickness. If the screed is more than 50mm allow 1 day per 1mm up to 50mm and then extra time for every millimetre over 50mm. Using this formula you would expect a drying time of 75-100 days for a 75mm screed layer. Other common types of screed have different drying times so
