Masonry Block Cap, 12x16in (10 Sets, 2 Per Set)

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 carton contains ten sets (2 per set) of single-use Masonry Block Caps.

Features:

• Cost-effective alternative to sulfur capping, ideal for QC testing applications
• Reduced time, labor, equipment
• Load uniformity and protection of machine platens
• Less time spent mixing, cutting, and measuring

Deslauriers introduces the first UNBONDED CAPPING SYSTEM for compression testing of concrete masonry units!

• Convenient and uncomplicated.
• No mixing, cutting or measuring.
• Clean and economical, saving time and labor.
• Accurate and consistent. Based on comparison tests this unit indicates excellent results versus capping with hydrocal gypsum performed according to ASTM C140.

The block cap compresion pad is a firous composite laminated to tough plastic sheeting.

The composite flows into the irregularities of the CMU, thus distributing the test load uniformly-with no damage to the cell stems. The plastic sheeing provides rigidity and provides

protection to machine platens.

TEST DATA

Forty6"xa·x16"normalweightconcretemasonry units (CMU) and forty a·x8" x 16" normal

weight concrete masonry units (CMU) were tested in compression using two different types of capping materials. The first 20 of each size CMU were capped in accordance with ASTM C 140 with Hydrocal gypsum. The remaining 20 of each size CMU used a foam plastic composite pad as the capping material.
