ABSTRACT:
An apparatus for forming concrete articles of uniform density, which includes means for forming concrete into the form of the articles, and means for sensing the density of concrete in each area of formation in the forming means as the article is being formed, comparing the sensed density to a preset density, and compensating for variation of the sensed density from the preset density responsive to such comparison, such that the density of concrete in each area of formation in the forming means as the article is being formed equals the preset density.
