Environmental performance of ordinary and new generation concrete structures—a comparative analysis

Abstract

The development of concrete technology results in a new generation of cement-based concrete such as high-performance concrete, self-compacting concrete and high-performance, self-compacting concrete. These concretes are characterised by better parameters not only in terms of strength and durability but also rheology of the mixtures. Obtaining such properties requires the adoption of a different composition and proportion of ingredients than ordinary concrete. The greater share of cement in these concretes causes an increase in the energy consumption and emissions (per unit of concrete volume) at the production stage. However, use of new generation concrete allows for a reduction of overall dimensions of a structural element, due to the increased strength parameters. Such a solution may finally result in lower consumption of resources and energy, as well as a decrease of gas emissions. The article presents the results of a comparative environmental analysis of ordinary and new generation concrete structures.

Optimizing Concrete Grade for a Sustainable Structural Design in Saudi Arabia

“…The decision to focus on concrete with a compressive strength of 40 MPa and higher in this study was purposeful and in keeping with the project's unique setting. It is recognized that, in actual projects, designers frequently choose conventional compressive strength concrete, and this observation is well-justified [70]. The apparent disparity between this study's recommendation of higher compressive strength to align with sustainability aims and the widespread usage of 50 MPa (selected choice) concrete in actual projects can be explained by the multidimensional nature of construction decision-making.…”

The influence of the demolition process on the environmental impact of reinforced concrete structures based on recycled aggregate

“…The difference between the Ecopoint indicators is insignificant and amounts to 1%, which reflects the minor influence of demolition on the total environmental impact generated in the production processes of all components of the concrete mixture and steel. Despite the fact that aggregate generally occupies 60% to 75% of the concrete volume (70% to 85% by mass) [1,16] its environmental impact is dominated by the production processes of cement and, as in the present case, steel as well as other technological processes [13,22] that require large amounts of energy and affect the depletion of abiotic resources.…”

Selected Properties of Self-Compacting Concrete with Recycled PET Aggregate

“…Compared to other materials, concrete is relatively environmentally friendly; therefore, the eco-improvement of the performance characteristics of concrete must be multiphased and customized to the location of its implementation. The analysis of applied solutions taking into account the whole life cycle of the building object is considered crucial for concrete construction [ 5 , 6 , 7 ]. Therefore, the influence of design strategies on environmental and economic efficiency [ 8 ], as well as solutions favorable to the creation of an environmental profile, are being investigated.…”
