<p>A method for fabricating a concrete slab upon a surface, the concrete slab having a final thickness and having, upon drying, a maximum dry density, the method including steps of providing a body of no-slump concrete, the no-slump concrete including a combination of aggregate and paste; dispensing the no-slump concrete upon the surface in an even depth layer which has an upper surface and includes an air volume, a portion of the paste residing at an upper surface of the even depth layer; removing a portion of the air volume from the no-slump concrete layer by compaction; trowel mulching the paste which resides at the upper surface; and trowel transporting the mulched paste horizontally over the upper surface to form a smooth concrete paste upper slab surface.</p> |
