Effect of Heat Treatment on the Pore Structure and Drying Shrinkage Behavior of Hydrated Cement Paste
The effect of a short heat treatment on hydrated cement paste has been investigated by measuring the weight and length changes of specimens as they undergo various combinations of heating, drying, and resaturation. Heating a cement paste to 60°C coarsens the capillary pore system, decreases the volume of mesopores, and increases the degree of polymerization of the silicates. In addition, the sa...
متن کاملSingle-Point Imaging of Partially Dried, Hydrated White Portland Cement
Moisture content in concrete has a major influence on the concrete samples with spin-echo imaging methods (15, 16) . The spin–spin relaxation times of water in these rehydration durability and mechanical properties of the material during its service life (1, 2) . Resistance to corrosion, ability to experiments is only a few milliseconds so the quality of traditional spin-echo images is disappoi...
متن کاملThe phase behavior of hydrated cholesterol.
The thermotropic phase behavior of cholesterol monohydrate in water was investigated by differential scanning calorimetry, polarizing light microscopy, and x-ray diffraction. In contrast to anhydrous cholesterol which undergoes a polymorphic crystalline transition at 39 degrees C and a crystalline to liquid transition at 151 degrees C, the closed system of cholesterol monohydrate and water exhi...
متن کاملModification of low-pH calcium aluminate cement to enhance stability for immobilisation of metallic wastes
Cementing systems based on calcium aluminate cement (CAC) have been studied as an alternative cement matrix for the encapsulation of intermediate level wastes (ILW) arising from the nuclear industry. CAC-based systems have great potential for the incorporation of aluminium containing ILW owing to the near-neutral internal pH of these binders. However, CAC-based binders usually undergo phase con...
متن کاملElectrical Conduction Behavior of Cement-Matrix Composites
As structural materials, cement-matrix composites have received much attention in terms of their mechanical properties, but relatively little attention in terms of their electrical conduction properties. Nevertheless, the electrical properties are relevant to the use of the structural materials for non-structural purposes such as sensing and electromagnetic interference (EMI) shielding. The abi...
