Early hydration behaviour of portland cement containing tartaro- and titanogypsum
AbstractPortland cements containing tartaro- and titanogypsum were respectively hydrated for up to two hours at a water: cement ratio of 0.5. They were compared with a Portland cement containing high grade natural gypsum hydrated similarly. The cement containing tartarogypsum produced much more ettringite than those with titanogypsum and natural gypsum. Comparisons were made with previous examinations of the hydration of Portland cements containing other by-product gypsums. Reasons for the observed hydration behaviour of the Portland cements with tartaro- and titanogypsum are discussed.
ResumenOs cimentos portlands que contêm o tartaro- e o titanogesso foram respectivamente hidratados próprio para duas horas à proporção água: cimento 0.5. Foram comparados com um cimento portland que conteve um gesso natural duma alta qualidade, que foi hidratado semelhantemente. O cimento que conteve o tartarogesso produziu mais da etringite que esses que contiveram o titanogesso e o gesso natural. As comparações foram feitas com as investigações da hidratação dos cimentos portlands que contiveram os outros gessos que são os produtos accessórios. As razões para a hidratação observada dos cimentos portlands que contiveram o tartaro- e o titanogesso são discutidas.
