Concrete Cube Test Register

The 28-day clock a spreadsheet cannot ring.

Record a pour once — site, grade, cast date, slump, ticket number, where it went in the structure — and CubeRegister works out when every specimen is due to be broken. You get a reminder the day before and on the day itself, and it keeps reminding you while a test is overdue, until the result is in.

RECORD THE POUR IN UNDER A MINUTE Site, mix grade, cast date, slump, how many specimens and what shape, pour location, delivery ticket number, and a photo of the ticket or the specimens in the tank. The cast date is the only date you enter. Everything else counts forward from it.

THE 7 AND 28-DAY CLOCK Pick the ages this set is scheduled for — 3, 7, 14, 28 or 56 days. Each one gets its own due date and its own reminder, and an age stops reminding you the moment you record its result. No more scrolling a spreadsheet on a Friday afternoon hoping nothing was missed.

STRENGTH AS YOU TYPE Enter the failure loads in kN and see the strength of each specimen appear beside the field, with the average and how it compares to your target underneath. Cube 150, cube 100, cylinder 150 x 300, cylinder 100 x 200, or your own cross-sectional area. MPa or psi.

YOUR THRESHOLDS, NOT OURS You set two percentages in Settings: what the average has to reach, and what the weakest single specimen has to reach. Every result is compared to those two numbers and nothing else, and both of them are printed on the register you export, so whoever receives it can see exactly which figures were applied. CubeRegister is a record-keeping and reminder tool. It does not assess, interpret or approve concrete, and it is not a substitute for the judgement of the responsible engineer.

ONE REGISTER PER SITE Export a site's whole register as a landscape PDF or a CSV: cover page with the client and the engineer, then a row per set per age with the cast date, the pour location, the grade, the slump, the ticket, the test date, every load, every strength, the average and the outcome. Send it to the main contractor without rebuilding it by hand.

A FREE STRENGTH CALCULATOR Specimen type, loads, answer. No site, no set-up, no sign-in, and no limit — free forever, for everybody. Save what you worked out as a real cube set when you want to keep it.

EVERYTHING STAYS ON YOUR PHONE No account. No sign-in. No cloud sync. No upload. Your sites, your clients and your results are on the device, and a register leaves it only when you share the file yourself.

FREE, AND PREMIUM Free: 2 sites, 15 cube sets, the full reminder ladder, and the strength calculator with no limit at all. Premium: unlimited sites and cube sets, the PDF and CSV register, unlimited photos per set, the wider 3 / 14 / 56-day ages, and no ads. One-time lifetime purchase, or monthly and yearly if you would rather.

Built for the site engineer, the technician and the small testing lab who keep a concrete pour card, a cube test record or a concrete test register — on a phone, in the rain, next to the mixer.
