The bulk cement industry to green low carbon development is an important way to implement the strategy of green growth, and great measures to realize the sustainable development of national economy. Facing the new situation of energy resources and environment constraints, more to strengthen, improve the utilization of social resources, protect the natural resources is imminent. How to do this, starting from the reality of our country, find a with Chinese characteristics on the development of the green, low carbon economy way of bulk cement and promote the whole process of cement production, circulation and use of bulk chemicals, green, low carbon, intensification and industrialization is before us a major issue.
“The 12th five-year”Development of bulk cement industry direction and priority areas
“The 12th five-year”Bulk cement industry development direction: perfect the bulk cement industry and the supply chain is extended, meet the needs of the development of modern construction; Upwards extends development waste slag, tail mineral sand and gravel aggregate, extends downward development of ready-mixed concrete and ready-mixed mortar, cement materials products, lateral balance development of the third party logistics services industry to achieve economies of scale, comprehensively enhance the management level of trade and industry. Key areas: it is to raise the level of comprehensive utilization of resources, to further promote the comprehensive utilization of industrial waste, improve the utilization efficiency of social resources, protection of natural resources. Strive to promote the popularization and application of artificial sand and natural sand implement some or all of the alternative, especially manufacturing and utilization of waste slag, tail mineral fine aggregate. Utilization of urban construction, the transformation of the construction waste generated in the factory processing, to replace the natural application.
Bulk cement belongs to low emissions, low energy consumption, low pollution mode of low carbon economy, it is the efficient utilization of resources and recycling as the core, the clean production and comprehensive utilization of waste integrated to achieve the goal of improve energy use efficiency. In the process of production through the special container used repeatedly, saving bags and reduce the loss of the cement in the circulation process to save packing cost and reduce the consumption of resources for the cement production process; In use process through the factory and the way of intensive production, the dispersed traditional extensive on-site mixing concrete and mortar production mode, centralized implement intensive of ready-mixed concrete and ready-mixed mortar modern mode of production, to drive the reuse of solid industrial waste, In the circulation process through the development of new industries, cultivate the modern logistics, speed up the construction and development of China's cement requires specialization, socialization, appropriate to the scale of the third party logistics service system, adopt efficient modern logistics technology, to further reduce from cement production to use in the field of logistics cost.
Speed up the cement & other; Ready-mixed & throughout; Use the pace, implement low-carbon green building. Green low carbon building refers to the building life cycle, including building materials production and planning, building design, construction, use, management and dismantle process series, consume a minimum of the earth's resources, using the least energy and make a minimum of waste buildings. And the cement & other; Ready-mixed & throughout; Use, can be a large number of industrial waste residue is used as the admixture (composite materials), offset the adverse impact of industrial wastes to the environment, effectively reduce the environment load. If further using the modern scientific and technological achievements to maximize resources comprehensive utilization, such as the environment load is the heaviest of the three kinds of ash, coal gangue, slag, industrial waste residue powder industrial cities respectively to thermal activation, chemical activation and mechanical activation, the potential of hydraulic in the extreme state of interface stability, become activated admixture (composite materials), then you can make cement concrete production play a civilization & other; Street sweeper & throughout; Role. In both economy and environment, the effective use of existing resources, to further improve the environment, greatly reduce the impact on the environment.
Increase the cement & other; Ready-mixed & throughout; Its use and realize the low carbon ecological architecture. Low carbon ecological architecture is a building as possible as you can the local environmental features and natural factors, such as topography, climate, sunshine, air, water, and make it accord with human habitation, and reduce all kinds of unfavorable to the human body and mind of any environmental factors. Ready-mixed mortar can all use artificial mechanism of sand instead of natural sand and gravel, the product quality without any adverse effects. Artificial mechanism of sand is to set down some mining residues or limestone, cement tailings waste and construction waste, gangue, steel slag and other industrial solid waste in crushing screening, ready-mixed mortar production of the required particle size requirements. Both to recycling, can reduce environmental damage, and at the same time the ready-mixed mortar as one kind of wall material can be in saving energy and reducing consumption in action & other; Good helper & throughout; , the civilized construction methods showed the characteristics of green ecological construction, and the special thermal insulation mortar because of its characteristics of thermal insulation, waterproof, moistureproof, heat insulation of the reflected the advantage of saving energy and reducing consumption in building materials, so as the third largest energy-consuming industry & ndash; & ndash; Construction, ready-mixed mortar as wall materials necessary show the effect of saving energy and reducing consumption is astonishing. Completely accords with the concept of low carbon economy development in China. As far as possible does not destroy the local environment factor circulation, ensuring the health of ecological system.
Increasing the cement & other; Ready-mixed & throughout; Use, to achieve sustainable low carbon buildings. Low carbon sustainable architecture refers to the sustainable development of planning, architecture, content range from construction materials, building, city area size, etc., as well as related to their functionality, economy, society, culture and ecological factors. Cement & other; Ready-mixed & throughout; Use, mainly through the development of ready-mixed concrete and ready-mixed mortar to implement low carbon sustainable buildings, concrete construction process to reduce the concrete construction process pollution to the environment pollution is mainly in the field mixing caused by the noise, dust, etc., and watering construction noise, etc. Reduce construction noise concrete measures including development of commercial concrete, reduce the mixing, improvement of construction technology for reducing environmental load, and the integration of environment, and is conducive to habitant health. Its aim is to reduce energy consumption, save water, reduce pollution, protect the environment, protect the ecological, health protection, improve the productivity and benefit future generations.
Extend the policy guidance as required by the bulk cement industry chain and safeguard measures
Extend the policy guidance as required by the bulk cement industry chain and safeguard measures to accelerate the green low carbon development of bulk cement industry is a systematic project, comprehensive measures must be taken to establish long-term mechanism, a powerful security system. Bulk cement industry chain, as a result of industrial solid waste and construction waste utilization and processing, involved in production, transportation, handling, reuse levels, only if all the effective linkage are unified management, collaborative cooperation, and to form a closed industrial solid waste and construction waste processing chain, really realize the recycle of industrial solid waste and construction waste.
