Process for producing water permeability ecological concrete

Abstract

The invention relates to a process for producing water permeability ecological concrete, the process is characterized in that: (1) the designed water permeability concrete communicating pore space rate reaches 15%-30% to satisfy the requirement of water permeability and air permeability; (2) the concrete intensity reaches more than C10 to satisfy the requirement of mechanical property; (3) the increase of concrete cost is no more than 10% of the current cost to satisfy the economic requirement. A traditional design method of the concrete proportioning ratio (ie. an assumed density method and an absolute volume method) takes intensity as a base, and is a method for designing a proportioning ratio according to a water cement ratio rule. An overall calculation proportioning ratio design method provided by the invention takes workability, intensity and endurance as bases, water consumption and sand ratio calculation formulas can be deduced through a concrete volume model, and the combination of two formulas and the water cement ratio rule enables realization of the composition of FLC and HPC and the overall calculation of the proportioning ratio. Compared with the traditional design method, the overall calculation enables a concrete proportioning ratio design with overall quantification from a concrete proportioning ratio design with semi- quantification, which trends to science from experience. Compared with a traditional proportioning ratio design, the overall calculation is more convenient and faster to obtain the optimized concrete proportioning ratio.

Description

【Technical field】 [0001] The invention relates to a production process of permeable ecological concrete, in particular, and according to different places of use and different functional requirements, different mix ratio designs of permeable concrete are proposed. 【Background technique】 [0002] As an engineering structural material, concrete is widely used in urban construction. While it creates living space for us, it also brings great damage to the earth environment on which we depend. Protecting the global environment and taking the road of sustainable development has become a common concern of the whole world. Concrete in the 21st century must not only meet the requirements of mechanical properties, but also minimize the load on the earth, reduce the adverse impact on the earth, and be able to coordinate with nature and coexist with the environment. In this context, the development of concrete puts forward the development direction of ecological and green concrete. [...

Problems solved by technology

[0003] According to statistics, more than 80% of the urban surface is currently covered by buildings and concrete pavements. This dense material lacks air permeability and water permeability, and has poor ability to adjust air temperature and humidity, resulting in the so-called "heat island" phenomenon in urban areas.

At the same time, a large area of ​​dense concrete cover prevents rainwater from permeating to form groundwater, which affects the natural ecological balance and increases the burden on urban drainage facilities and sewage treatment facilities.

Moreover, the impermeable ground is easy to form water on the surface, which affects the comfort and safety of the road.

In addition, the space constructed by the dark gray concrete lacks vitality, and the urban landscape is monotonous and dull
