Method for preparing vegetation form cellular concrete

Abstract

The invention provides a method for preparing vegetation form porous concrete, adopting the 'pre-coating' technology, a slurry body with specific compositions coats coarse aggregates to form a sphere with a relatively uniform particle diameter, based on the physical coacervation of the sphere and the agglutination of the surface slurry body of the sphere; and the porous and macroporous structure, the cementation between solid phases of which is good and gas phases of which are communicated, is formed. The method comprises the concrete preparation steps that: (1) the fluidity and the viscosity range of the slurry body used to coat the aggregates are determined, and the mixing ratio is worked out by an absolute volume method; (2) the four-step stirring working procedure and the shaping model of the combination of the vibration and the pressuring are adopted; and (3) hole spaces are subjected to alkali-sealing treatment. The invention solves the difficult problems existing in the prior method that because of the downflow of the slurry body, the distribution of the pore spaces is not uniform and the discontinuous pore spaces increase, and the alkalinity in concrete pore spaces is relatively high, which are adverse to the growth of plants. When the vegetation form porous concrete prepared by the method of the invention is applied to road shoulder separator inserts, construction roofs, protection banks and protection slopes and parking lots of a highway, and good landscape effects and ecological environmental protection significance are achieved.

AI Technical Summary

Benefits of technology

This new type material solves problems with existing methods such as complicated manufacturing processes or expensive materials used for its purpose due to their weakness at certain points during use. It also ensures that there's no damage caused by excessive pressure on cured soil when exposed to rainwater over time without losing any significant amount of work required before they become too strong again.

Problems solved by technology

This patented technical issue addressed in this study relates to developing an efficient way for protecting environments from harmful substances such as water pollution or excessive temperatures during winter periods caused by snowmobiles and truck traffic. Conventional methods involve adding layers of sand around the road edges where crops may hide, reducing their own purifying capacity. To solve these issues, there exists a new type called vegetated porous concretes (PC) containing tiny holes filled with calcium carbonate particles. These PC rocks allow roots to enter deeper depth while absorbing important mineral elements like nitrogen fertilizers. They provide excellent eco-friendliness properties when compared to traditional structures, allowing them to actively promote biodiversity within our planet.
