effects of water cement ratio and age on compressive strength Procedures used for preparing the high strength gypsum cement capping materials shall ensure that water cement ratios used for each batch provide the required strength NOTE 4—The water gypsum cement ratio should typically be between and
The wide range of gypsum facies observed all over the world and the strong heterogeneity that may be present even within a single facies often cause an inhomogeneous mechanical response that if neglected may be particularly dangerous in the framework of underground excavations In addition gypsum is particularly sensible to the presence of water
AbstractThis research aims at producing high strength water resistant gypsum based materials from used plaster moulds with the additions of glass cullet and cements and investigating the influence of glass cullet contents on their properties
If sulfur mortar high strength gypsum paste and other materials except neat cement paste are to be used to test concrete with a strength greater than 50 MPa [7000 psi] and their compressive strength is less than the cylinder compressive strength the manufacturer or the user of the material must provide documentation
