CAPPING CONCRETE CYLINDERS WITH NEOPRENE PADS

Concrete cylinders were tested for compressive strength using two capping systems. Neoprene pads confined in extrusion controllers were compared with sulfur-mortar caps for differences in testing variation, average strength, and economy. Cylinders tested with neoprene pads were found to exhibit slightly higher average compressive strengths--149 to 172 psi--with equal or less testing variation, than comparison cylinders tested with sulfur-mortar caps. Additionally, neoprene pads are substantially less costly and hazardous than sulfur-mortar caps.
