Masonry Block Caps offer a unique unbonded capping method for the compressive strength testing of masonry units. This cost-effective alternative to sulfur capping minimizes time, labor, expense, and equipment such as ladles and melting pots. A fibrous composite is laminated to the tough plastic sheeting, providing rigidity, proper load distribution, and protection of the machine platens. Composite material flows during compression to fill the irregularities in the concrete masonry unit, distributing test loads uniformly.
This method is comparable in accuracy to capping with hydrocal gypsum but is not noted in the ASTM C140 method. Block Caps are ideal for internal QC testing applications and eliminate the need for mixing, cutting, or measuring. Each set of caps is designed for a single-use. Each carton contains ten sets of caps.
