VITROBOND® SULFUR COMBOUNDS
CAPPING COMPOUNDS
Vitrobond® Capping Compound
Vitrobond is a mineral-filled, sulfur-based compound formulated for capping concrete test cylinders. It is easily melted, pours smoothly, possesses high compressive strength and gives consistent test results. Vitrobond has been used for many years by independent testing laboratories, pre-stressed concrete structures manufacturers and federal, state and local testing agencies. This compound is suitable for running compressive strength tests upon high strength concrete.
Vitrobond offers the following advantages:
Ready-to-use—just melt and pour
No mixing or possibility of low strength or erratic results from improper proportions
Does not require controlled room temperature or humidity conditions during pouring of caps
Does not require moist curing or other tedious handling procedures
Not affected by dry cylinders Can be tested two hours after cooling
Virtually no settling in the melting pot, thus, results are uniform from cylinder to cylinder
