Efficient nano materials for consolidation, cleaning and hydrophobization of porous historic materials have been developed in several European and national research proje [...]

Demolished concrete is often recycled as a crusher-run in Japan. It captures CO2 as the new surface is exposed to the air. This uptake is caused by carbonations of hydrat [...]

This study investigated the influence of the molten slag as fine aggregates of concrete on the structural performance of RC beams. In the loading test, the mechanical res [...]

Packing density is considered one of the most influential factors in fresh performances of mortar and concrete. There exist standardised methods for its determination, bo [...]

The consolidation and conservation of historic mortars requires materials which are compatible with the components originally used. The application of nano-lime offers su [...]

Concrete is represented as a two-phase material in this paper. Behaviour of a crack with its tip on the interface between two different materials - hardened cement paste [...]

The Kodokan, opened in August 1841 as the Mito clan s school. The Kodokan stone monument is made of marble called Kansuiseki. The spirit of Kodokan is curved on the surfa [...]

For high durability and strength, decreasing of the water to binder ratio of cement is needed by using of fly ash, blast furnace slag as mineral admixture. And it is poin [...]

Compared with the study on high-quality of recycled coarse aggregate, the study on recycling of recycled fine aggregate still has been limited. This study has quantitativ [...]

Application of the recycled aggregate is a promising technology for resource saving and low environmental impacts, which is more effectively performed when recycled fine [...]

The consolidation process of old renders with loss of cohesion is nowadays performed usually with inorganic compatible products, such as calcium or barium hydroxide or et [...]

Proposed paper focuses on review of filtration stability of the part of river Danube adjacent region in Bratislava providing realisation of treatment on Danube, designed [...]

For centuries the ruins of the Cathedral at Kirkjubøur in the Faroe Islands was exposed to the very humid and saline north Atlantic environment. Traditional maintenance [...]

Abstrakt: After mixing kaolin with water attractive and repulsive forces between kaolin particles initiate process of coagulation and peptisation, respectively. The coagu [...]

Despite of over forty years of research on over the world, the ideal grout for re-adhesion of delaminated wall paintings has not been invented. Along with the industry de [...]

In the fiber reinforced inorganic polymer (FRiP) strengthening system, an inorganic paste is used instead of an organic resin as the matrix and adhesives of fiber sheets. [...]

Lime water, esters of silicic acid and plastics are common materials used for the conservation of historic mortars. Injection grouts containing cement or hydraulic lime a [...]

Under the consideration of the bi-material notch composed of two orthotropic materials the potential direction of the crack initiated from the notch tip is determined fro [...]

This study aims to clarify the amount of CO2 fixation in demolished concrete under different exposure conditions, and in addition, it aims at computing the LCCO2 (Life Cy [...]

Loss of adhesion is one of the main forms of degradation of old renders; it can cause the separation of different render layers or the separation of the render and substr [...]

Dynamic fragmentation (disintegration of continuous body into smaller pieces under dynamic loading) is a physical phenomenon observed in many fields of engineering and sc [...]

In this work nano-titania in anatase form has been added to mortars containing (a): binders of either lime and metakaolin or natural hydraulic lime and, (b): fine aggrega [...]

In the domain of heritage buildings conservation, interventions must be designed, whenever possible, to maintain existing materials instead of their replacement by new on [...]

Glazed ceramic tiled façades are a cultural, architectural and social heritage that has to be protected in order to continue to have these history marks of our ancestors [...]

This paper summarises the preliminary results concerning an influence of the agitation conditions on the aggregation processes. The properties of formed aggregates affect [...]

The aim of this contribution is to investigate aggregation efficiencies when high (G= 260 s-1) and low (G= 60 s-1) intensity agitation is applied for a treatment of surfa [...]
