Concrete manufacturing method based on microbial composite additive

Abstract

The invention discloses a concrete manufacturing method based on a microbial composite additive. The method comprises the following steps: preparing a microbial additive, preparing a bacillus pasteurii bacterial solution, and preparing a bacillus subtilis bacterial solution; and putting the bacterial solution into a centrifugal machine for low-temperature centrifugation for 10 minutes, then putting into a low-temperature freeze dryer for freeze-drying, curing prepared culture powder, and then mixing with freeze-dried bacterial powder to obtain a bioactive additive; and then mixing with modified activated carbon according to a certain proportion, and putting into a tablet press for compression molding to obtain the tablet type strength additive. The additive is added into concrete according to a certain proportion, and the compressive strength of a concrete test block containing the additive is improved differently through hydraulic machine detection.

Description

Technical field [0001] The present invention belongs to the field of microbial and building materials, and more particularly to a concrete production method based on a microbial composite additive. Background technique [0002] Concrete additives refer to materials that are incorporated to enhance concrete performance before or during mixing or mixing process. Since the additive can effectively improve the performance of the concrete, and has a good economic benefit, it has been widely used in the construction area. With the continuous improvement of science and technology, the additives have become more and more applications, and the additives have become concrete. In addition to the five important components other than the four basic components. [0003] At present, the additives of concrete compressive strength include simple materials such as woodcuts, steel slag or water reduction agents such as complex treatment, modified fibers. The former cannot respond to a variety of en...

Problems solved by technology

The former cannot cope with a variety of environmental changes. In practical applications, various factors need to be considered, and the source of materials has a greater impact on its performance. The latter often uses or produces substances that have adverse effects on the human body during the modification process. In the process of material processing and application of materials, it may endanger human health and pollute the environment. At the same time, these methods are often costly and complicated.
