1. 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 comprising steps of:
(a) providing a body of no-slump concrete, the no-slump concrete comprising a combination of aggregate and paste;
(b) dispensing the no-slump concrete upon the surface in an even depth layer which has an upper surface and includes a volume of air, such dispensation upwardly exposing portions of the paste;
(c) removing a portion of the air volume from the even depth layer; and
(d) mulching the paste exposed at the upper surface and simultaneously horizontally transporting the mulched paste over the upper surface; wherein the paste mulching and transporting steps comprise steps of providing a trowel having a lower surface, and applying the trowel to and horizontally drawing the trowel over the upwardly exposed paste so that portions of said paste roll along the trowel's lower surface.
