Abstract The analysis, characterization, and comparison of modern and ancient mortars provide fundamental (by tracing the change in the raw materials and recipes used from the past to the present) and practical (obtaining modern mortars compatible with the ancient) knowledge. This work aimed to characterize modern and ancient mortars by investigating their phase composition, binder-to-aggregate ratio, hydraulicity, and hygroscopic properties. The used methods for analyses were powder X-ray diffraction, Fourier transforms infrared spectroscopy, and thermal analysis. A modern mortar (sample A) p

Abstract:

The use of high percentages of substitution of Portland cement by pozzolans can provoke the total consumption of portlandite. The present research proposes the study of ternary systems of Portland cement (PC), fly ash (FA), and hydrated lime (CH). After 180 days of curing, the mortar with 50% substitution of PC by FA obtained 65.9 MPa versus the mortars with an addition of 20% of CH and control mortar (100 PC) that obtained 69.9 MPa and 76.7 MPa respectively: this behavior is very positive value considering that tested FA containing mortars had a 50% of Portland cement.

Abstract:

Abstract The present work examines the Karsten tube penetration test to identify mortar types in existing masonry, for mortars containing air-lime or hydraulic binders. Mortar type identification is e.g. of relevance for the reusability of the fired clay bricks in the masonry, where a hydraulic binder content makes the mortar removal process significantly more difficult. The Karsten tube test makes it possible to make a simple and non-destructive mortar analysis on-site assessing the water absorption of the mortar, via the surface of the mortar joint alone. The present approach considers both

To reduce the water absorption of RFAs during mortar making, the prewetting method was utilized. All the mixtures were assembled with a volumetric cement-to-aggregate ratio of 1:4 and a consistency of 175 ± 5 mm. The properties in the fresh and hardening state of mortars were analyzed sepa

Ceramic blocks were pressed and fired at 890 ºC and mortars prepared with the proportion 1:1:5:0.5:2 of cement: hydrated lime: sand: PVA binder: water. The materials were tested in compression individually and in prisms w

Abstract:

Resin mortars and concretes have high water resistance and very good resistance to aggressive environment. For this reason, they are often used as repair or waterproof layers e.g. in tanks for liquids. Materials used in this regard should be characterized by relatively low shrinkage and high adhesion to a substrate.The research program was carried out on selected resin mortars composed of quartz sand and a two-component epoxy resin of high viscosity and adhesion to substrate. The shrinkage development of tested resin mortars was analyzed in the paper. The tests were conducted in automatic meas

Abstract:

The former construction mortar differ significantly from the currently used. In many cases the historic mortar have very good physical-chemical properties. Therefore, the method of preparation of these mortars are still interesting for modern technology. But there is no precise guidance in archival technology. Therefore, attempting to re-create the old recipes make it sometimes very difficult. Set of methods in the study of historic mortars allow comparative analysis, as well as the reproduction of ancient recipes for modern conservation and technology of construction materials.
