摘要
This paper presents equipment for the measurement of initial as well as final setting times of calcium phosphate cements containing alkali to achieve higher solubility. Until now, the self-setting process of cements also if alkali is integrated has been tested by using the "standard test method for time of setting of hydraulic-cement paste by Gillmore needles" in accordance to ASTM C 266 - 99. This procedure needs high man power and, furthermore, the results have been markedly influenced by individual experiences that are incorporated in the criterion "without appreciable indentation".
