Copy-and-Paste
Copy-and-Paste is a self-sustaining system generating sameness in different locations. The same urban grid, the same outfit, the same house, the same car appear everywhere; copies of each other pasted all around. Copy-and-Paste is there, unquestioned, and seem-to-be arbitrary. This thesis explores …

Ion diffusion from Sellafield OPC paste formulations
… chloride and carbonate. The cylindrical cement paste samples (CPS) having diameter of 3.2 cm and height 5.3 cm were immersed in re-circulating test solutions consisting of de-ionised water, concentrated Sellafield pore water (CSPW), diluted Sellafield pore water (DSPW) and bacterial inoculated …

A multiscale computational framework for cement paste
Cement paste is the matrix phase in mortar and concrete that exhibits a hierarchical structure spanning orders of magnitude in length scales. These complexities have prevented systematic studies of structure-property relationships. This understanding is necessary to design sustainable cementitious …

A nanochemomechanical investigation of carbonated cement paste
… in particular its principal component, cement paste, has an interesting relation with carbon dioxide. Concrete is a carbon dioxide generator-- it is estimated that 5-10% of atmospheric CO₂ comes from this source. Carbon dioxide is a concrete corroder-- it can penetrate into the porous concrete …

Occlusion of Dentin Tubules by Novel Prophylaxis Paste
Prophylaxis paste treatments are a standard part of biannual dental checkups. Prophylaxis pastes remove stains from teeth by polishing the surface of the enamel. Polishing essentially scratches the surface layer of enamel, thereby technically demineralizing teeth to achieve better aesthetics. The …

Modelling the Extrusion of a Hard-Metal Paste
Paste extrusion is a bulk forming technique used widely in the ceramics, food, metal and polymer industries, amongst others. This dissertation develops (i) measurements of the friction and bulk constitutive behaviour of pastes and (ii) numerical simulations of paste extrusion using these …

Textural Influence of Fruit Paste Type on Sensory Perception
Dried fruits and fruit pastes are nutritious ingredients with potential application in snack bar products that meet both consumer trends and health recommendations. Food texture is known to be an important factor in consumer liking and manufacturing processability. This project work focused on …

Investigation of the Dimensional Stability in DSP Cement Paste
… was systematically investigated for cement pastes with a wide range of microstructure features. It was found that saturated paste behaves anomalouly in response to temperature change, i.e., the thermal expansion is followed by a time-dependent delayed contraction at isothermal condition. …

Moisture permeability of mature concrete, cement mortar and cement paste
… specimens of concrete, cement mortar and cement paste with the bottom side in water or in moist air and the upper side in a relative humidity of 33 %. The distribution of the relative humidity within the specimen was measured, at stationary conditions, as well as the amount of water which pass …

Sulfate attack on cement paste with volcanic ash : durability analysis
… for Portland Cements to develop cement paste compositions for superior sulfate resistance with potential for durability and sustainable solutions. Pumiceous volcanic ash was used in preparing Roman hydraulic pozzolan concrete that was used to build the Bay of Naples. This study reports …
