A new model of the K-slump tester was developed that can be used to evaluate the slump of concrete in 40 sec. The new apparatus features an electronic digital readout giving the slump value to the nearest 1 percent. Experimental studies were performed in accordance with ASTM C 670 and C 802 using the new K-slump tester to determine its reliability and precision. The results indicate that the new apparatus is accurate and reliable in evaluating concrete slump.
