Heat Transfer Characteristics of a Low Density Concrete Wall. Final Report
Tests were conducted to evaluate thermal performance of three concrete walls. A normal-weight concrete wall, a structural lightweight concrete wall, and a low density concrete wall were tested in the calibrated hot box facility of Construction Technology Laboratories, a division of the Portland Cement Association. Experimental results are covered for the low density concrete wall. Test results for the normal-weight and structural lightweight concrete walls are described in separate reports. Each wall was subjected to steady-state, transient, and periodically varying temperature conditions in a calibrated hot box. Steady-state tests were used to define heat transmission coefficients. Data obtained during transient and periodic temperature variations were used to define dynamic thermal response of the wall. Thus, effects of heat storage capacity could be evaluated. Conductivities derived from calibrated hot box tests were compared with results from hot plate and hot wire tests. Hot wire tests were also used to evaluate the influence of moisture on thermal conductivity. Data obtained from dynamic tests were compared with steady-state calculations. (ERA citation 09:010073)
