Wet cast product is better when a structural product is needed and where much bigger pieces need to span large openings. The biggest difference between wet cast and dry cast stone is water content and the amount of slump (an industry term for how workable and pliable a synthetic stone mix is). Wet cast, commonly referred to as precast concrete, is a plastic or pour able concrete, the viscosity of which can be measured by a slump test. Speed: Dry cast production is typically faster than wet cast. The people at Steps Plus have been producing precast steps in Syracuse since 1967. Compressed air is introduced at the nozzle during wet process to enhance the spray characteristics. (Slump is a relative measurement in concrete consistency. The average speed of UPV for new precast concrete pipes was 4345 m/s and for old precast concrete pipes was 3200 m/s, The difference between the UPV values of the wet and dry surfaces of concrete suggests that the variance may be caused by moisture content because the saturated concrete consistently exhibited higher UPV values . Spalling of top concrete slab at bridge joint was also reported. Wet joint involves the use of epoxy glue at the mating precast segments. Dry Cast – manufactured from zero slump concrete. Here’s a quick side-by-side comparison: Cost: Cast-In-Place is often more cost-effective for small-scale or highly customized projects, while Precast can be cost-effective for larger, repetitive projects. Acid Etching – Process of applying a solution of hydrochloric or muriatic acid and water to the exposed surface of Cast Stone in order to remove the cement film from the aggregates, achieving a fine-grained finish which simulates natural cut stone.
