DETERMINATIONES DIRECTE DEL PH DE CEMENTOS IN PROCESSO DE PRISA.—In general, le massa interne del cementos esseva minus acide que le superficie externe. Le pH de omne le cementos montava in le curso del tempore. Inter le materiales investigate, cementos a phosphato de zinc e a argento e phosptiato de zinc habeva le plus rapide augmentos, Le plus acide del materiales investigate esseva le cementos a cupro rubie e a cupro nigre. Le pH del cementos a silicate jaceva inter illo del eementoa a cupro e illo del cementos a phosphato de silicium. Esseva trovate un relation directe inter le pH de silicatos e le proportion de liquido a pulvere: quanta plus sgisse le mixtura, tanto plus alte le pH.
