Green recycled aggregate concrete
(Construction and Building Materials, 2013)
The paper presents results of experimental investigation of concrete made with recycled concrete aggregate, low cement content and high content of different mineral supplements. Such concretes belong to "green" or "eco" ...
The role of service life in Life Cycle Assessment of concrete structures
(Elsevier Ltd, 2020)
In comparative Life Cycle Assessment (LCA) of concrete structures it is of crucial importance to provide the functional equivalence of compared alternatives. Most commonly, the comparison is performed between the structures ...
Hydro energy potential of cooling water at the thermal power plant
(Elsevier Ltd, 2011)
The hydro energy of the gravity water flow from the coal-fired thermal power plant units to the river in an open cooling system of turbine condensers is determined. On the basis of statistical data for a long time period, ...
Environmental assessment of green concretes for structural use
(Elsevier Ltd, 2017)
This paper presents a comparative environmental assessment of several different green concrete mixes for structural use. Four green concrete mixes were compared with a conventional concrete mix: recycled aggregate concrete ...
Long-term behaviour of reinforced beams made with natural or recycled aggregate concrete and high-volume fly ash concrete
(Elsevier Ltd, 2018)
Six simply supported reinforced concrete beams were tested under sustained loads for 450 days. The beams were made from natural aggregate concrete (NAC), recycled aggregate concrete (RAC) and high volume fly ash concrete ...
Multicriteria optimization of natural and recycled aggregate concrete for structural use
(Elsevier Ltd, 2015)
Recycling of concrete waste to produce recycled concrete aggregates (RCA) and its use in the production of structural concrete is the way towards reducing the depletion of natural mineral resources and the amount of ...
Long-term behaviour of reinforced beams made with natural or recycled aggregate concrete and high-volume fly ash concrete
(Elsevier, 2018)
Six simply supported reinforced concrete beams were tested under sustained loads for 450 days. The beams were made from natural aggregate concrete (NAC), recycled aggregate concrete (RAC) and high-volume fly ash concrete ...
A database on flexural and shear strength of reinforced recycled aggregate concrete beams and comparison to Eurocode 2 predictions
(Elsevier Ltd, 2016)
A comprehensive database of recycled aggregate concrete and companion natural aggregate concrete beams' flexural and shear strength was compiled from 217 experimental results. Strict criteria were applied to determine the ...
Effects of recycled concrete aggregate on stiffness and rutting resistance of asphalt concrete
(Elsevier Ltd, 2017)
The objective of this research was to assess the possibility of using recycled concrete aggregate (RCA) in asphalt mixtures. The experimental research included 10 asphalt mixtures with partial natural aggregate substitution ...
Physical and mechanical properties of hemp fibre reinforced alkali-activated fly ash and fly ash/slag mortars
(Elsevier Ltd., 2020)
Two alkali-activated mortars with different solid prime materials were analysed. The first mortar contained fly ash, had lower density, higher water absorption, lower compactness, lower compressive strength, similar flexural ...
