Abstract Urbanization and mass construction of housing will increase the consumption of cement and available natural resources such as sand and water. The production of cement generated from various industries leads to the emission of carbon dioxide gas in huge quantities into the atmosphere and creates serious problems in handling and disposal. So, the replacement of conventional materials with alternative materials for the preparation of concrete is needed. If the alternative cementitious and industrial waste materials are found suitable in replacing the ingredients of concrete then it can reduce the cost of construction. The present paper represents an experimental study of low carbon emission alternative concrete by replacing conventional concrete materials with alternative materials like geopolymer as binding material, copper and ferrous slag as fine aggregates, steel slag as coarse aggregates, and alkaline solution as an activator. Study made to examine the properties of low carbon emission alternative concrete proposed. The fresh and hardened state characteristics of low carbon emission alternative concrete are evaluated for both oven and ambient curing conditions. It is noticed that the time taken to achieve the strength by oven curing is less than ambient curing but had no major difference in load-carrying capacity and the results obtained are in good concurrence with conventional concrete.

Low Carbon Emission

The sustainable development of mankind is a matter of concern to the whole world. Environmental pollution and haze diffusion have greatly affected the sustainable development of mankind. According to previous research, vehicle exhaust emissions are an important source of environmental pollution and haze diffusion. The sharp increase in the number of cars has also made the supply of energy increasingly tight. In this paper, we have explored the use of intelligent navigation technology based on data analysis to reduce the overall carbon emissions of vehicles on road networks. We have implemented a traffic flow prediction method using a genetic algorithm and particle-swarm-optimization-enhanced support vector regression, constructed a model for predicting vehicle exhaust emissions based on predicted road conditions and vehicle fuel consumption, and built our low-carbon-emission-oriented navigation algorithm based on a spatially optimized dynamic path planning algorithm. The results show that our method could help to significantly reduce the overall carbon emissions of vehicles on the road network, which means that our method could contribute to the construction of low-carbon-emission intelligent transportation systems and smart cities.

Low Carbon Emission

As a huge systematic project, low-carbon emission reduction involves all of the world's vital profit. From the perspective of cooperation and competition, the dynamic equilibrium process is analyzed around the low-carbon emission reduction game background in this paper. Focus on the relevant principles of game theory to give a global analysis to global carbon emission reduction market and to explain the phenomenon during the global carbon emission reduction process. Try to expose the planning and motivation of the various interest game groups.
