A concrete pump was set up on the Grace Church construction site on Thursday, July 31. A conventional transit mix concrete truck pours concrete into the pump truck, and it is then forced through the long yellow pipe to a flexible hose. In the photo above, the wet concrete is being pumped into all the holes in the concrete blocks. Since the holes line up vertically, the concrete fills the entire void from bottom to top to lock the blocks together. This is in addition to the installation of steel reinforcing rods, which are visible sticking out of the tops of the blocks. The end result is a masonry wall of tremendous strength.
