scope note
  • A rosy red volcanic clay that has been used as a pigment and a component in cement; pozzolana itself possesses little or no cementitious value, but in finely divided form and in the presence of moisture, it will chemically react with calcium hydroxide at ordinary temperatures to form compounds possessing cementitious properties. Pozzolana is mined at Pozzuoli near Naples, Italy. It has been used since ancient times by the Romans. (en)
  • Siliciumhoudend of silicium- en aluminiumhoudend materiaal dat zelf weinig of geen cementerende waarde bezit, maar dat in fijnverdeelde vorm en bij aanwezigheid van vocht bij normale temperaturen chemisch zal reageren met calciumhydroxide, waardoor er verbindingen ontstaan met cementerende eigenschappen. (nl)
  • 一種呈玫瑰紅的火山黏土，為用來製作顏料及水泥的成分；火山灰黏土本身僅具些微或完全不具水泥的價值，然而，其經過精細分割的型態遇到水氣，在常溫下便會與氫氧化鈣產生化學反應，形成具水泥屬性的合成物。火山灰黏土開採於近義大利那不勒斯的波佐利〈Pozzuoli〉，自古代由羅馬人使用至今。 (zh-hant)
  • Material silíceo o sílico-aluminoso que posee en sí mismo escaso valor como cemento, pero que tiene una forma finamente dividida y que, en presencia de humedad, reacciona químicamente con hidróxido de calcio a temperatura ordinaria para formar compuestos que poseen propiedades de cemento. (es)
