“…New technologies introduce more and more complex composite materials which could not be tested in a long time period before implementing. Composites using waste or recycled materials are already an increasingly important element of buildings [16][17]. Also the energy sector promotes the use of fly ashes (spoil material of coal burning) in building industry as a substitute of cementous binders.…”

Rapid technological progress in construction requires that more and more attention should be paid to human security issues. Threats occur both at the stage of building facilities and during their use. Some impacts are easy to identify during construction stage like shocks and vibrations, others are hidden from sight and direct sensing like the harmful effect of chemicals. In addition to accidents that happen on construction sites, there are still objective threats, which may occur throughout the lifetime of the facility. In addition to clearly perceptible ones such as earthquakes, hurricanes, fires, there are hidden threats as well: bacteriological contamination, radiation or chemical interactions that occur in time. This article points to the most common chemical hazards. Examples of chemical threats occurring in construction at the stages of design, construction and use of buildings will be given below.

“…in the case of assumption of the upper cohesion value and the minimum value of internal friction angle. One thing is certaineach case must be subjected to the analysis individually, because the complexity of this issue makes it very easy to make a mistake during the attempts to categorize the parameters of soil-cement, especially in the case of high organic parts amount and when other binders or granular materials are implemented to build the composite internal strength [18,19].…”

Parameters of the constitutive model of geomaterials formed with the use of DSM dry technology

Numerical modelling of geomaterials is always complex due to the variability of parameters within the soil massif (created in the natural geological processes) and the orthotropy caused by this. In the case of the soil substrate modification with the use of hydraulic binders, this issue is complicated even more due to the fact the degree of mixing can be differentiated for various areas, while in the dry mixing technology, it is additionally differentiated with the depth of consolidation stress. Additional factor that makes it difficult to predict the behaviour of stabilised soil is the possible content of organic parts. Due to the development of substrate reinforcement technology, as well as the growing market for such works, a need emerged to provide parameters of the numerical model for various materials or, at least, to provide a method for reverse analysis on the basis of available data. This paper presents an example of calibration of the selected numerical model (through parameter selection of this model) based on the conducted examinations of cubic sample in the conditions of uniaxial compression. The results of laboratory tests, reverse analysis in the numerical model with a pre-selected strength hypothesis and finally, the recommendations for selection of the model in calculations of real structure on a reinforced substrate, are demonstrated.

“…The usage of crushed concrete fines (i.e., previously selected C&D waste) in decorative concrete has been presented by [18]. The authors have found that the admixture of the crushed concrete fines has little effect on the colour characteristics of the decorative concrete products, however this evidence might not be valid for non-selected C&D recycled materials.…”

Valorization of Fine-Grain Construction and Demolition (C&D) Waste in Geosynthetic Reinforced Structures

Current environmental awareness compels all citizens to reduce the production of waste and use recycled materials. Recycled materials coming from Construction and Demolition (C&D) waste are progressively being used in civil engineering applications, such as base and sub-base layers of transport infrastructures and concrete production. However the fine grain fraction of C&D recycled materials is not considered appropriate for those applications, being frequently landfilled instead of reused. This paper assesses the possibility of using fine grain C&D recycled materials as backfilling of geosynthetic reinforced structures (embankments and retaining walls), replacing the soils typically used in the construction of these structures. The study has involved physical, mechanical and environmental characterization of C&D recycled materials, characterization of the interfaces between the fill material and three geosynthetics, through direct shear and pullout tests, and the evaluation of the potential damages induced by the C&D recycled materials on the short-term tensile behaviour of the geosynthetics. The results presented in this paper support the suitability of using C&D recycled materials in the construction of geosynthetic reinforced structures and thus diminishing our carbon footprint, through the reduction of the environmental impacts induced by C&D waste landfilling and by the extraction of natural aggregates.
