Utterly Exhausted

I want to block a water line, and keep it blocked when the pressure comes back on.
I am working on a house in Central America with a damaged water pipe under the sink. The damaged pipe formerly had a steel pipe threaded into it. The steel pipe corroded and attempts to remove it left the corroded threaded part stuck inside the pipe in the wall.
Since this is a concrete block house, the water line was embedded in concrete during construction. Not easy to modify.
After extensive attempts to remove the corroded pipe from the threads, I decided to block the pipe. (There is another line next to it, and houses here dont plumb hot water to sinks, if they have it at all. Thus, only one line is needed.)
I tried the following to block the pipe:
1) Stuffed some plastic bags down it (keep cement in step 2 from traveling).
2) Filled a PVC cap with a cement designed to cure after 10-15 mins. Painted the concrete wall with concrete adhesive & put the cement-filled cap over the pipe. The idea was to cap the line with concrete and forget about it.
After letting the cement cure for 2 hours (adverised time 10-15 mins), I turned the water pressure back on. Looked fine for 10 mins but then started dripping.
How can I block this water line? (assume that I can use a cutting wheel or drill with appropriate bit to remove the concrete cap). Equipment and materials are limited here.
