Oct 20, 2010 · For a new multistory concrete building, I am placing a 4" thick lightweight concrete topping on top of the normal weight structural slab at various loions (the required "depressed" area accounts for 7080% of the floor plate, hence the entire structural floor is set at 4" down and the other 2030% is brought back up to finish floor line by topping).
Slab Thickness. Because of the support provided by the reinforced concrete joists every 24 inches (610mm), a much thinner slab section is required.
Despite the moisturerelated challenges that lightweight concrete poses, properly designed and constructed lightweight concrete floor slabs offer a number of efficiencies over normalweight concrete slabs that project teams should consider.
Lightweight concrete mixture is made with a lightweight coarse aggregate and sometimes a portion or entire fine aggregates may be lightweight instead of normal aggregates. Structural lightweight concrete has an inplace density (unit weight) on the order of 90 to 115 lb / ft³ (1440 to 1840 kg/m³).
With so many variables that may affect the final drying schedule of a lightweight concrete slab, only accurate moisture testing can provide the green light for finish or flooring installation. For lightweight concretes, the only concrete moisture test allowed by the ASTM is relative humidity (RH) testing.

RH Best Testing Practices Explained. as an acceptable test method for lightweight concrete. Some specs still include calcium chloride kits, but this may not meet the ASTM requirements for your project. ASTM F2170 RH testing is the recommended test method for monitoring moisture conditions in a concrete slab, because it is the best
In addition to the field implementation, three concrete slabs with and without a UHPC overlay were tested in the laboratory. The results showed that a UHPC overlay in the positive moment region increased the strength by 18% while showing a more ductile (IHRB Project TR683) Preparation of this report was financed in part
