Karol-Warner | Shear Boxes

https://www.karolwarner.com/shear-boxes Karol Warner shear boxes are made in a wide variety of sizes to test round or square soil direct shear specimens to determine its shear strength. Designed for Karol-Warner Direct and Residual Shear Machines these shear boxes meet test specification required by ASTM D3080 and AASHTO T 236 “for direct shear testing of” for testing the shear strength of soils. Units are divided horizontally, allowing application of a vertical confining load to the specimen and horizontal shearing stress to the lower half of the box, while the upper half remains stationary. AND once shear failure has been obtained and recorded, the force direction can be reversed to determine residual shear values. Karol Warner’s Shear Boxes are available in a variety of sizes to test circular or square specimens. AND each unit includes top and bottom Porous Stones and a stainless steel loading ball. The Shear Box Counterbalance (Model 2000-75 purchased separately) the top half of the shear box with specimen dimensions 2.5in (63.5mm) or smaller to ensure its weight will be less than one percent of the applied normal force, as required in ASTM test specifications.
