POZZOLANIC PROPERTIES OF GLASS POWDER IN CEMENT PASTE

SEM Analysis of the Interfacial Transition Zone between Cement-Glass Powder Paste and Aggregate of Mortar under Microwave Curing

In order to investigate the effects of microwave curing on the microstructure of the interfacial transition zone of mortar prepared with a composite binder containing glass powder and to explain the mechanism of microwave curing on the improvement of compressive strength, in this study, the compressive strength of mortar under microwave curing was compared against mortar cured using (a) normal ...

Assessement of the Waste Glass Powder Pozzolanic Activity by Different Methods

The purpose of this work is the study of the use of waste glass obtained from crushed containers and building demolition as partial Portland cement replacement in mortar and concrete. For this, the waste glass must have the characteristics of pozzolanic material. In this context, a study of the pozzolanic activity of two types of glass clear and green coloured, with varying the particle size of...

Structure and Physical Properties of Hardened Portland Cement Paste

Decalcification shrinkage of cement paste

Decalcification of cement paste in concrete is associated with several modes of chemical degradation including leaching, carbonation and sulfate attack. The primary aim of the current study was to investigate the effects of decalcification under saturated conditions on the dimensional stability of cement paste. Thin (0.8 mm) specimens of tricalcium silicate (C3S) paste, white portland cement (W...
