You will need 1 1/3 cubic yards for each 8×6′ form. The best and fastest way to get the job done is to order a ready mix concrete truck asking for a 4,000 psi at a slump of 6 or 7. Slump is simply a measure (1-10) to gauge the consistency of concrete. A slump of 7 will enable you to pour and move the concrete into each beam with minimal effort…

The usual cost to order a concrete truck ranges from $80-$100/cu.yd. Plus a $60-$100 delivery fee. Prices vary area to area, and the distance to the concrete company. The bottom line: An 8×6′ form (needing 1 1/3 cubic yards of concrete) will usually cost a maximum $250. Figure roughly $350 for two 8×6′ forms.
