Shear strength testing mold for waterproofing membranes

Product Introduction: Shear Strength Mold for Load-Bearing Waterproof Membranes This product is designed for testing the shear strength of load‑bearing waterproof membranes. Two surfaces of a membrane of specified dimensions are bonded to concrete blocks using cementitious materials, forming shear‑strength test specimens. After curing under prescribed conditions and for a set duration, the specimens are mounted on a tensile testing machine. At a controlled pulling speed, the two concrete blocks are pulled in the tangential direction along the membrane until failure occurs, thereby determining the membrane’s capacity to resist tangential shear forces. The shear strength of the membrane is calculated as the ratio of the maximum force recorded during the test to the effective bonded area. This mold complies with GB/T 21897-2008 “Load‑Bearing Waterproof Membranes.” Technical Parameters: 1. Internal dimensions of the mold: 40 × 20 × 10 mm 2. Connection end diameter: φ20 mm 3. Overall dimensions: 90 × 30 × 20 mm 4. Weight: 0.25 kg

Shear strength testing mold for waterproofing membranes

Description

Product Introduction

This product is used for conducting shear strength tests on waterproofing membranes. Two surfaces of a membrane of specified dimensions are bonded to concrete blocks using cementitious materials, thereby forming a shear‑strength specimen. After curing under prescribed conditions and for a specified duration, the specimen is mounted on a tensile testing machine. At a set crosshead speed, the two concrete blocks are pulled in the direction tangential to the membrane until failure occurs, enabling determination of the membrane’s capacity to resist shear forces. The ratio of the maximum force recorded during the test to the effective bonded area represents the shear strength of the membrane. This method complies with GB/T 21897‑2008 “Waterproofing Membranes—Shear Strength.”

Technical Specifications:

1. Mold internal dimensions: 40×20×10 mm

2. Connection end: φ20mm

3. External dimensions: 90×30×20 mm

4. Weight: 0.25 kg
