<p>1. A method for manufacturing prefabricated panels formed of bricks, comprising the steps of sequentially : - placing a uniform layer of a hardenable product on the bottom of a hollow mold ; - laying down bricks on this product at the required spacings while applying a pressure on the bricks so as to force said product upwards into the spaces provided between the bricks ; - pouring concrete over the bricks, so that it will coat the bricks ; - after the concrete has set, turning the panel over and removing the hardenable product, characterized in that use is made of a hardenable product consisting of a mixture of barite with water and bentonite with the following proportions : barite from 1.500 to 3.100 kg water from 0.300 to 0.800 kg bentonite from 0.015 to 0.022 kg</p> |
