A building is a structure constructed using various methods. An enormous amount of resources and energy is invested in the construction of buildings. In order to reduce the energy spent and the environmental load incurred by the construction of buildings, it is necessary to first reduce the energy spent in and the environmental load of each material involved in the construction of buildings. To achieve low carbon greenhouse gas emissions and energy goals, locally as well as internationally, both public and private sectors have focused on improving the environmental impact of products. This paper discusses the low carbon activities of the construction material industry. Here, we investigate the trend of each country in policy support and technological innovation for realizing low carbon activities. We also analyze the carbon dioxide emissions of certified carbon labeled construction materials. Because the process of producing construction materials makes it difficult to reduce the generation of carbon, only 68 items of a total of 962 items were certified as carbon labeled materials. However, leading material manufacturers are ready to recognize certified carbon labeling as an important process in order to gain the customer's trust and play a leading role.

Environmental and economic cycles under varying geopolitical uncertainties can lead to unsustainable patterns that significantly and negatively affect the welfare of nations. With the ever-increasing negative environmental and economic impacts, the ability to achieve sustainability is hindered if the implications are not properly assessed in challenging geopolitical crises. The infrequent and fluctuating nature of these challenging geopolitical settings causes disregard and neglect for exploration within this issue. In this study, a comparative life cycle assessment was conducted as a method to evaluate the environmental and economic impacts of construction material flow across country boundaries. Based on the results found from the life cycle assessment, an environmental forecast and sensitivity analysis were established. Considering the State of Qatar as a case study, asphalt and bitumen, cement, limestone, sand, and steel were analyzed from gate-to-gate depending on transportation mode and distances used within both the pre-crisis and post-crisis sub-periods, comparing carbon emissions and costs. The results showed that the mode of transport plays a significant role in terms of carbon dioxide emissions as opposed to distance traveled. However, the increase in distance coupled to the majority shift from land to sea-based transport resulted in an overall increase in carbon emissions and costs post-crisis. In addition, the analysis of the environmental and economic impact assessment using the average CO2 equivalent (CO2-e) per kilogram and the unit price of the five primary construction materials has shown a significant, 70.68% increase in global warming potentials (GWP) after the crisis, coupled with an increase in the overall cost. An assessment of environmental and economic impacts during geopolitical uncertainties allows for the significant ability to realize sustainable measures to greatly reduce economic and environmental degradation.

Cement concrete is a most used construction material, due to its enormous demand worldwide in the construction sector. Concrete serves many purposes in different adverse conditions, there are many advantages but there is one limitation that is concrete is not flexible. Concrete Canvas brought a revolutionary change in the construction materials called Geosynthetic Cementitious Composite Mats (GCCMs) which as many applications and used as an alternative to conventional concrete. It is a flexible, concrete canvas that gets hardens on hydration to form a thin, durable, waterproof and low-carbon concrete layer. Concrete Canvas may find its tremendous scope in the Construction sector as fire resistance and water proofing material. The concrete canvas has a self healing property thereby adds good benefit to the life of material and economically because of its zero percent repairs maintenance. Even though if the concrete canvas gets damaged after a period of time, it gets self healed with the contact of water which helps in the hydration process. This paper mainly focuses on the case study done on the applicability of concrete canvas for fire resistant, Water proof and bulletproofing with the help of AP State Police and to explore different applications in Construction sector as well as Defense sector.

Abstract One of the most important parameters that is currently used in public and private procurement in building process is the lowest price. The legislation of Latvia permits that an estimate forming process does not include criterions of quality, durability, and the potential high cost of maintaining the building during the exploitation time. That allows the constructor to reduce the cost estimate by using cheaper construction product or technology and does not let to provide the highest possible quality and the basic principle of sustainable construction. One of possible construction cost reduction solutions is the replacement of building material with equal building material, at the same time assessing the quality and replacement impact on the direct costs of estimate. The tasks of the research are: (1) to do literature review on what is an estimate, what an estimate includes and the basis of estimate; (2) to analyse the existing construction estimate, to evaluate the used construction materials and to study technical characteristics of materials, to explore a specific construction junction; (3) to replace the selected construction materials with analogous, thus reducing the direct costs of estimate; (4) to evaluate the affect of the price of the construction material on quality; (5) to compare the obtained cost estimate with the current cost estimate; (6) to implement laboratory research and to compare technical characteristics of the construction materials and analogue materials in order to check if they are the performing parameters that are defined in the declaration of performance. After comparing of the obtained direct costs of construction and analysing the quality of construction materials it is possible to provide the most appropriate offer of the direct costs of estimate to satisfy the customer’s interests.

The need for a vast quantity of new buildings to address the increase in population and living standards is opposed to the need for tackling global warming and the decline in biodiversity. To overcome this twofold challenge, there is a need to move towards a more circular economy by widely using a combination of alternative low-carbon construction materials, alternative technologies and practices. Soils or earth were widely used by builders before World War II, as a primary resource to manufacture materials and structures of vernacular architecture. Centuries of empirical practices have led to a variety of techniques to implement earth, known as rammed earth, cob and adobe masonry among others. Earth refers to local soil with a variable composition but at least containing a small percentage of clay that would simply solidify by drying without any baking. This paper discusses why and how earth naturally embeds high-tech properties for sustainable construction. Then the potential of earth to contribute to addressing the global challenge of modern architecture and the need to re-think building practices is also explored. The current obstacles against the development of earthen architecture are examined through a survey of current earth building practitioners in Western Europe. A literature review revealed that, surprisingly, only technical barriers are being addressed by the scientific community; two-thirds of the actual barriers identified by the interviewees are not within the technical field and are almost entirely neglected in the scientific literature, which may explain why earthen architecture is still a niche market despite embodying all the attributes of the best construction material to tackle the current climate and economic crisis. This article is part of the theme issue ‘The role of soils in delivering Nature's Contributions to People’.

Introduction. To solve the problem of increasing the concentration of greenhouse gases in the atmosphere leading to global environmental problems, searches of ways to reduce carbon dioxide emissions are conducted in the field of construction material production. lower burning temperature, lower carbon dioxide emissions, and further binding of the exuding carbon dioxide to insoluble compounds, which determine the obtainment of a dolomite lime-based material with high mechanical properties are characteristic of dolomite lime. Materials and methods. Dolomite rock with a fraction of 5 mm to 10 mm was burned in a laboratory chamber furnace, while the calcined product was ground to pass through a 1.25 mm mesh sieve and tempered with water. The dolomite lime obtained after hydration was pressed into cylinder samples with a diameter and a height of 30 mm. The samples were subjected to forced carbonization in a particular chamber at a certain carbon dioxide concentration and for a certain chamber holding time. Results. The physicomechanical characteristics of the experimental carbonized samples were determined (compressive strength of 2 to 36 MPa with an average density of 1500 to 1800 kg/m3). The samples got hard under conditions of an increased carbon dioxide concentration. The results obtained under laboratory conditions were tested under industrial conditions at a functioning enterprise by pressing a single brick batch, its subsequent carbonate hardening in a pilot industrial chamber for forced carbonization, and determination of the main standardized properties. Conclusions. The low-burned carbonate-hardened dolomite lime allows reducing carbon dioxide emission during production by means of lowering the burning temperature with the subsequent use of the exuding carbon dioxide for the implementation of carbonate hardening of dolomite lime-based products.
