Abstract
Summary A specimen of natural tobermorite from Crestmore, California, was studied by a new extraction technique. This investigation revealed that tobermorite can be resolved into two fractions. One of them is a soluble species and the other insoluble. The infra-red spectrum of the soluble polysilicate derived from tobermorite is not identical with the infra-red spectrum of the soluble polysilicate derived from a Portland cement paste. The insoluble derivative has the same morphology as the original tobermorite.Keywords
