HVAC Calculations and Duct Sizing

Using Equation 5, the thermal resistance of the 4 inch concrete wall with 2 inch insulation is R = 1 6 +1.0 + 2.17 + 4 10 + 2.17 +.45 + 1 1.63 = 26 (hr-ft 2 –F)/Btu Equation 2 gives the heat conducted through the wall area minus the window area assuming 8 q

U Values - The Concrete Society

U Values The conduction of heat is quantified using the thermal conductivity coefficient, or k-value (W/m.K), of the materials used in its construction. For further information see U-values: understanding heat movement, published in CONCRETE in March 2003, pp 42–43. in March 2003, pp 42–43.

Designing Concrete Mixes for Increased Fire or Heat …

1974/8/1· One factor that is seldom considered in striving for a high degree of fire or heat resistance in a concrete structure is the design of the concrete mixture itself. And yet, to name just one example, a study has shown that an appropriate change in the type of aggregate used can sometimes double the fire endurance of concrete.

Fire resistance - Concrete Centre

In most cases, concrete does not require any additional fire-protection because of its built-in resistance to fire. It is a non-coustible material (i.e. it does not burn), and has a slow rate of heat transfer. Concrete ensures that structural integrity remains, fire
