Chapter 32—Preplaced Aggregate Concrete
The term “preplaced aggregate” (PA) concrete describes a method of placing gap graded concrete. As an alternative to blending the fine and coarse aggregate, cement, and water and placing the mixture in a form, coarse aggregate is preplaced in the form and a structural grout is injected into the coarse aggregate mass in such a way as to fill void spaces where it hardens to form dense homogeneous concrete. The process was developed by Wertz to whom a U.S. patent [1] was issued in 1943.
