In recent years, the control of setting time of concrete has become significant due to the development of various kinds of concrete. In general, JIS 6204 specifies the test method of setting time of mortar mixtures by penetration resistance. However, since measuring the penetration resistance in the case of long setting time requires considerably a great deal of complicated work, the simple way to predict the setting time could be advantageous in quality control at the concrete industry. This paper proposes an evaluation method of setting time of mortar mixtures by mortar thermocouple method comparing the test results by a mortar thermocouple method with penetration resistance using the sample mortars containing the diverse kinds of admixtures and three different aggregates. A mortar thermocouple method could evaluate the setting time by automatically measuring a thermal hysteresis.
