<p>PRE-CAST HEATING PANEL A heating panel comprises a fiber-rein-forced mortar prepared from a mixture of a cementing material, a finely divided mineral aggregate and water and incorporating a fibrous, electrically non-conductive reinforcement material homogeneously dispersed therein, and a flexible electric heating element embedded in the fiber-reinforced mortar. The heating panel of the invention can be made relatively thin while still exhibiting good flexural, compressive and tensile strength properties, thus being relatively light in weight for ease of handling and low cost transportation.</p> |
