Mortars and plasters—how to characterise hydraulic mortars
Archaeological and Anthropological Sciences, 2021 Mortars are heterogeneous building materials whose raw materials, manufacturing processes and application conditions have evolved continuously throughout history. The fact that apparently small changes in the components or dosages of mortars can affect their overall performance in the masonry makes the study of historic mortars a complex task that ...

The Weathering of Mortar [PDF]
Nature, 1922 MR. RICHARDSON'S letter (March 9, p. 310) anent the above calls, I think, for some further remarks. My observations never led me to conclude that the growth of moss was in any way responsible for the development of the ridge-and-ring markings upon the surfaces of old and exposed mortar.

Mortars and plasters—How to characterize aerial mortars and plasters
, 2021 Aerial mortars and plasters have been widely used in construction throughout history, and their compatibility with historic mortars and plasters has led to their recent re-adoption. This paper reviews the prominent features of aerial mortars and plasters,

Rheology of semi-solid fresh cement pastes and mortars in orifice extrusion [PDF]
, 2013 Short fiber-reinforced semi-solid fresh cement pastes and mortars, tailored for extrusion, have much lower water-to-binder ratio and higher viscosity than normal cement pastes or mortars. The rheology of these pastes or mortars cannot be characterized by

Dredged marine sand as a new source for construction materials
Materiales de Construccion, 2012 This work deals with the use of dredged marine sand (DMS) in pastes and mortars as construction material. Different materials from two Spanish ports were used: DMS-0 from Sant Carles de la Ràpita and DMS-A, DMS-B and DMS-C from Barcelona.

Mortar Boundary Elements [PDF]
SIAM Journal on Numerical Analysis, 2010 We establish a mortar boundary element scheme for hypersingular boundary integral equations representing elliptic boundary value problems in three dimensions. We prove almost quasi-optimal convergence of the scheme in broken Sobolev norms of order 1/2.
