Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a preparation process of an ecological concrete additive, which solves the problem of adding a large amount of harmful ingredients to the existing concrete additive, which is not friendly to the environment, and is likely to cause environmental pollution during long-term use. Realize the use of crop straw as the main fiber component in the additive to make the concrete additive achieve better performance, which cannot achieve the purpose of saving energy, environmental protection and cost, and cannot realize the problem of using concrete additives on the premise of ensuring green environmental protection

Abstract

The invention discloses a preparation process of an ecological concrete additive. The preparation process specifically comprises the following steps: S1, raw material weighing: firstly, respectively weighing the raw materials according to the required weight ratio through batching equipment, and storing the weighed raw materials through storage equipment for later use; S2, crushing treatment; S3, fermentation treatment; S4, mixing treatment; and S5, forming and mixing. According to the preparation process of the ecological concrete additive, crop straw can be adopted as a main fiber component in the additive, so that the concrete additive achieves more excellent performance, the purposes of saving energy, protecting the environment and saving the cost are well achieved, the concrete additive is used on the premise of ensuring green and environment-friendly effects, a large amount of harmful components are prevented from being added into the concrete additive to cause environmental pollution, the ecological concrete additive is environmentally friendly, can be used for a long time, and is very beneficial to environmental and ecological protection.

Description

technical field [0001] The invention relates to the technical field of building material production, in particular to a preparation process of an ecological concrete additive. Background technique [0002] Vegetation concrete ecological slope protection technology is to mix cement, loam, organic matter, plant seeds, fertilizers and vegetation concrete additives in an appropriate proportion to obtain a vegetation concrete base material, and then use a sprayer to spray it on the slope that needs greening to form a spray layer, and then sprinkle water for maintenance ecological slope protection technology. On most slopes, anchor rods and hanging nets are often constructed on the slope before spraying to enhance the integrity and stability of the sprayed layer of the base material. This technology has been popularized and applied on a large scale in various water conservancy, mine, building, road slope ecological restoration and ecological protection projects. Through a lot of...
