The structural effectiveness of textile reinforced mortar (TRM) composites relies on their load transfer capacity to the substrate and interaction between mortar. bond plays a crucial role in mechanism TRM composites. Despite some recent investigations, deep understanding still needs be gained textile-to-mortar develop suitable analytical numerical predictive models, improve test methods, orien...

The article discusses the interaction of metabolic products a wood-destroying fungus dry rot species (Serpula lacrymans (Wulfen) P. Karst.) with commonly used lime mortar. Mortar samples in presented experiment were made mostly laboratory conditions so as to make it possible set input and determine initial properties examined samples. Matured mortar placed cultivation boxes growth Serpula expos...

This paper evaluates the influence of water content and mixing conditions (mixing time sequence addition constituents) on fresh state properties lime-based materials their impact hardened properties. Higher contents allowed an increased fluidity lower torque, yield stress plastic viscosity values. In turn, a longer with aggregate caused progressively stiffer mortar substantial increase in value...

The interest in restoration and maintenance of old masonries towards their durability is nowadays combined with the concept sustainability need to implement more suitable materials for building heritage interventions. This has led importance having a better knowledge air lime mortars, namely on effect pozzolanic additions, curing conditions evolution at early stages. study consisted characteriz...

In the history, different mortars compositions have been used during ages in masonry structures. Lime was frequently adopted past. summary, there are two main types of lime: hydraulic and non-hydraulic (aerial). The present review deals with second type. Herein, studied lime is specially obtained from thermal decomposition, called calcination, limestone (calcium carbonate (CaCO3). Aerial a comp...

This paper summarizes recent investigations into the structural and material response of ambient-dry wet clay-brick lime-mortar masonry elements, with focus on those used in heritage structures Historic Cairo. In addition to cyclic tests large-scale walls subjected lateral displacement compressive gravity loads, studies included complementary small scale panels specimens. It is shown that moist...

Research on prehistoric mainland Southeast Asia is dominated by mortuary contexts, leaving processes such as the transition to sedentism relatively understudied. Recent excavations in southern Vietnam, however, have recovered new evidence for settlement. The authors report investigations at neolithic site of Loc Giang (3980–3270 cal BP) where excavation revealed a vertical sequence more than 30...

The objective of this work was to assess the use biomass fly ash (BFA) as cement replacement material or an alkalinity source in high volume mortar and concrete. Mortar formulations were prepared with different types replacement: from thermal power plants, BFA, a blend two pozzolans, small amounts BFA or/and hydrated lime (HL). tested both fresh hardened state. by ashes led decrease mechanical ...

Use of lime as construction material is limited mainly by low initial strength. These properties can be improved adding pozzolanic materials, but the evolution reaction usually needs older ages than 7 days. Alkali-activated or geopolymers, are good-performance materials that produced with residual waste. The combination traditional and new lead to uses mortars. This paper studies a lime/pozzola...
