Physical and chemical assessment of lime–metakaolin mortars: Influence of binde...
Gameiro, André; Santos-Silva, António; Faria, Paulina; Grilo, João; Branco, Tiago; Veiga, Rosário; Velosa, AnaCement & Concrete Composites 45 (2014) 264–271 ; This work evaluates the influence of binder:aggregate ratio on the mineralogical and mechanical properties of air lime–metakaolin mortars. Mineralogical analysis showed that binder:aggregate ratio affects the extent of carbonation and pozzolanic reactions with curing. The pozzolanic reaction occurs mostly at lower curing times (28 days), while, at higher curing ...
Mechanical and mineralogical properties of natural hydraulic lime-metakaolin mo...
Grilo, João; Santos-Silva, António; Faria, Paulina; Gameiro, André; Veiga, Rosário; Velosa, AnaConstruction and Building Materials 51 (2014) 287–294 ; This paper investigates the mechanical and mineralogical characteristics of natural hydraulic lime NHL3.5 (NHL) mortars with different% of lime replacement by metakaolin (MK) under different laboratory and natural marine curing conditions. Tests were conducted at different curing ages, using compressive and flexural strength tests and thermogravimetric an...
Influence of curing conditions in lime-metakaolin blended mortars – A mineralog...
Cardoso, Daniel; Gameiro, André; Santos-Silva, António; Faria, Paulina; Vieira, Ricardo; Veiga, Rosário; Velosa, Ana3rd Historic Mortars Conference, 11-14 September 2013, Glasgow, Scotland ; 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 strengt...
