Is it possible to exclude the “steaming” process when making prestressed floor slabs?
Using the D-5 admixture (3% of the cement weight), it is possible to replace the “steaming” process with normal heating at 30 – 50 < sup > 0 </sup > C, i.e. to replace the steaming process with fan heater with automatic temperature control. To avoid loss of moisture from concrete, the slabs must be covered with film.
