Pouring the concrete slab

This house will be built, as most are here, on a concrete slab.  On the preceding page were photos showing the fill dirt (clay) being added to the lot, piled up, and graded flat in preparation for pouring the concrete slab.  The next set of photos shows the work done in and on the fill -- digging footers for the concrete slab and installing the plumbing that goes into the ground below the slab.

This page (actually, three pages because of the number of photos) shows how the concrete was poured to make the slab.  We used 78 cubic yards of 3,000 PSI concrete (at $73.00 per yard).  We started pouring at 0700, Tuesday, 9 August, and by 1000 hours the slab was ready for final polishing.

Concrete is delivered in ready-mix trucks, each carrying 8 cubic yards.  A concrete pump truck is set up on the site and the ready-mix trucks dump their loads into a hopper on the pump truck.  The wet concrete is then pumped through an arm on the pump truck and into a flexible hose.  the pump truck operator has a remote control device that talks by radio to the truck -- he moves the arm and starts and stops the pump as the concrete pouring and finishing crew needs him to.

On to the photos.

This first photo shows the slab area ready to pour.  Note the following:
(1) 6mil polyethylene covering the entire area below the slab; this is done to prevent the clay from sucking all the water out of the concrete -- concrete must cure slowly;
(2) the concrete bricks spread out over the poly; they support the wire mesh that provides reinforcing to the concrete;
(3) the rebar -- steel reinforcing rod, 1/2 inch X 20 feet long; four sticks of rebar run through each footer; the 6 X 6 wire mesh is tied to the rebar, thereby putting continuous reinforcing through the entire slab.


The pump truck.  Coming in from the left side of the photo is a chute from one of the ready-mix trucks -- concrete from the truck is poured into the hopper at the end of the pump truck then pumped through a hose carried by the long, articulated arm on the pump truck.


This guy operates the pump truck.  He carries with him the wireless remote control that is hanging around his neck -- using this, he controls the pump and the arm, thus, he can move the arm where the crew pouring the concrete wants it as well as starting and stopping the flow of concrete.  Note the round object by his left foot, tied to four other similar objects with grey PVC conduit.  These are the boxes into which electrical outlets for the floor will be set -- the wires will run through the grey conduit.  Before pouring the concrete, the electrician measured exactly where on the floor plan these outlets go then transferred these measurements to the slab and set these boxes and the conduit.  The conduit then runs to where a wall will be so he can connect the cables when he wires the house.


Here is a view of the site with the crew pouring the first footer.  All footers are filled with concrete then the slab is poured.  Note the pump truck operator; one guy is holding the hose, guiding it to pour into the footer; the rest of the crew is standing by to move concrete to fill any voids.

Because of the number of photos of pouring the slab, I have divided this into three pages.  Click on this link to go to page two, pouring the slab.
