Tension tests from the center of concrete slab (35Mpa) using Reidbar Grade 500

Set 1:
12mm Diameter Reidbar Grade 500 (Rb12)

Imbedded Item (mm)	Hole Diameter (mm)	Hole Depth (mm)	Applied Load (kN) at Failure	Average Load (psi) at Failure	Failure Mode

* The above table indicates that as the diameter of the hole was increased. The average loading on Rockite increases due to the expansion qualities of Rockite.

Test Results 5: Strain Bearing Ability. USA Test Results

The compound shall produce a setting with an average strain bearing ability for each respective bolt and opening size, as shown in the following chart.

mm	inches	mm	inches	mm	inches	Kilogram	Pounds
9.52	3/8	31.4	1 ¼	76.2	3	3,900	8,600

31.75	1 ¼	107.9	4 ¼	304.8	12	42,729	94,200

* All bolts shall be equipped with a washer large enough to fit the diameter of the opening with only enough tolerance so that the washer will be free to reach and rest snugly against the head of the bolt at the bottom of the opening.

** Depths shown are based opening drilled in sound concrete having a compressive strength of 24.8 Mpa/3600psi. In the case of weaker concrete, the depth shall be increased to provide a greater purchase to the concrete slab. This minimizes the danger of failure due to fracture of the concrete when subjected to extreme strains.

*** Data determined by tests in which the strains recorded were limited to stresses sufficient to rupture mild steel bolts of each representative diameter. In no case was the setting injured.
