The most common radioactive agents for well cementing are 53 I 131 (half-life: 8.1 days) and 77 Ir 192 (half-life: 74 days). The iodine is generally available as a liquid. Sand or glass beads tagged with iridium 192 are often available in areas where tracers are used with hydraulic fracturing fluids.

These admixtures give a much higher performance than the normal plasticizers. They are also known as plasticizers or high-range water reducers (HRWR), reduce water content by 12 to 30 percent and can be added to concrete with a low-to-normal slump and water-cement ratio to make high-slump flowing concrete. Flowing …
