Concrete Core Sections Can Provide Concrete Sampling Results. Fire Findings. Volume 3 Number 1. Winter 1995

Abstract: Fire Findings conducted an experiment to determine the best way to test for accelerants in concrete. On a concrete surface, a triangle section was marked where the gasoline was poured. Samples were take before the fire to be compared with those taken after the fire. The structure was burned to the ground and the debris was cleared. Core samples were taken by drilling through the concrete floor seam. Flour samples were taken by moistening the area and spreading flour. The flour samples produced no detectable accelerant residue. However, the core samples all contained detectable traces of gasoline. Fire Findings concluded that taking core cement samples produces the best results.
