Assessment of the interaction of polycarboxylate superplasticizers in hydrated lime pastes modified with nanosilica or metakaolin as pozzolanic reactives
Two polycarboxylate ether copolymers were assessed as superplasticizers (SPs) for hydrated lime pastes modified with two reactive compounds, nanosilica (NS) and ceramic metakaolin (MK). Characterization of the molecular structure of the SPs by Size Exclusion Chromatography, XRD, FTIR and MALDI-TOF (Matrix Assisted Laser Desorption Ionization Time-of-Flight) mass spectrometry was performed. The ...
متن کاملMicrostructural Changes Induced by CO2 Exposure in Alkali-Activated Slag/Metakaolin Pastes
The structural changes induced by accelerated carbonation in alkali-activated slag/ metakaolin (MK) cements were determined. The specimens were carbonated for 540 h in an environmental chamber with a CO2 concentration of 1.0 ± 0.2%, a temperature of 20 ± 2°C, and relative humidity of 65 ± 5%. Accelerated carbonation led to decalcification of the main binding phase of these cements, which is an ...
متن کاملInfluence of curing conditions in air lime-metakaolin blended mortars – A mineralogical and mechanical study
The need to formulate mortar compositions with adequate durability and compatibility is nowadays one of the major challenges in historical buildings repair. The incorporation of pozzolanic materials as addition or replacement of lime is viewed as a solution to these challenges regarding the increase in hardening time, mechanical strength, water resistance and durability. This paper includes par...
متن کاملSemiotic and nonsemiotic MUD performance
Using performance and theatricality as metaphors to describe MUD adventure games this paper starts out by defining a difference between ’performative’ and ’theatrical’ acts within MUDs. Performative acts differ from theatrical acts in that they are effecting ’real’ changes to the MUD environment, thus directly influencing the game in one way or another. It is argued that to understand the perfo...
متن کاملDirect contribution of the seagrass Thalassia testudinum to lime mud production
Seagrass beds contribute to oceanic carbonate lime mud production by providing a habitat for a wide variety of calcifying organisms and acting as efficient sediment traps. Here we provide evidence for the direct implication of Thalassia testudinum in the precipitation of aragonite needles. The crystals are located internally in the cell walls, and as external deposits on the blade, and are simi...
