What are U Values? A U Value is a number that illustrates the rate at which heat is transferred through a structure. The standard unit of measurement for this is W/m²K. Broken down this means: The rate of heat flow in watts directed over 1 x 1 metre square of a structure. The lower the U-Value the more efficient the structure is, for instance. * soil layers of the two reference cases and the thermal transmittance values (U -value) of different structural components: a) reference case 1 with a radiator heating system, b) case 2 with a floor heating system*. frost insulation: EPS insulation 100 mm, λ = 0.037 W/m K m / W 7 3 . 0 = U 2 K slab: concrete 40 mm, λ = 1.7 W/m

Since slab strength and performance are so influenced by soil behavior, the slab designer should seek full informa-tion about the soil conditions on a giv-en site. The flow chart in the figure provides an orderly approach to ob-taining basic soils information (Ref. 1). To design a slab on grade, the engi-neer needs a value for the modulus o The Area of a Concrete Slab calculator computes the Concrete Slab surface area of a rectangular slab.. INSTRUCTIONS: Choose units and enter the following: (w) the Width of the slab,(L) the Length of the slab.Surface Area (A): The surface area of the slab is returned in square feet (ft 2).However, this can be automatically converted into other area units (e.g. square meters) via the pull-down menu Concept of providing expansion joint gap between two concrete member is to avoid collision due to the thermal expansion of the members.

- Steps to calculate the Reinforcement required for Slab: Deduct the cover for finding length of bar. Evaluate the length of the distribution bar. Calculate the Value of 'D' (Depth of slab- Top cover- Bottom cover) Find out the No. of Bars. Compute the Total wt of steel required for slab reinforcement
- ULTILAYER SAMI is a crack resisting asphalt interlayer for concrete based roads. Over 1,200km of concrete pavement are thought to be in use on Highways England's strategic road network, with an even greater length in existence across the local authority network. The thin asphalts used to overlay this concrete frequently suffer from reflective.
- A web-based application has been developed by Pitt for the FWD Analysis of Concrete Slabs (Pitt - FACS) that can be used to assist in establishing overlay design inputs (elastic modulus of the concrete and k-value), assessing joint performance, and in identifying possible void sbeneath the slab
- The concrete cover is essential for every building element (Slabs, Beams, footings), where the reinforcements are present. We use concrete covers to maintain the proper arrangement of steel bars and provide a cover for bars.
