Abstract

The effect of potassium nitrate as an accelerator in plain concrete was investigated. Fifteen concrete cubes were cast with 0, 5, 10, 15 and 20 % by weight of potassium nitrate. The compressive strength was measured after 7, 14 and 28 curing days Other parameters including the workability, initial and final setting times were tested. Compressive strength of the plain concrete decreased as the content of the potassium nitrate increased. The workability and setting times decreased as the content of the potassium nitrate increased.
