Problems solved by technology

[0003] At present, most of the oil shale semi-coke is stacked at home and abroad, which not only occupies a large amount of available arable land, but also pollutes water resources, deteriorates water quality, and causes waste of resources
As an additional product of oil shale, oil shale semi-coke is also often used as concrete material for construction. However, in practical applications, it is found that oil shale semi-coke powder is loose and porous and has strong water absorption. The superplasticizer added in the concrete preparation process has strong adsorption, which not only increases the dosage of the superplasticizer, but also deteriorates the workability and workability of the concrete, which in turn affects the on-site pouring construction, which greatly Limit resource utilization of oil shale semi-coke

Abstract

The invention discloses an oil shale semicoke adsorption inhibitor and application thereof in concrete preparation. The adsorption inhibitor is prepared by the following steps: sequentially adding 50-52.5 parts by weight of an anti-corrosion rheological agent, 5-20 parts by weight of methanol, 0.5-2 parts by weight of sulfonated melamine, 2-5 parts by weight of EDTA, 20-30 parts by weight of an organosilicon compound and 5-10 parts by weight of stearate into a mixing container, and fully and uniformly stirring, wherein the anti-corrosion rheological agent is a 'microbead' water-reducing active micro aggregate. The adsorption inhibitor is doped into the industrial solid waste oil shale semi-coke powder, so that the problems of strong water absorption, high water reducing agent adsorption and the like of the oil shale semi-coke are solved, the use amount of the water reducing agent is reduced in concrete production, and the obtained concrete is good in workability and workability; and due to a certain dispersing and grinding-aiding effects, the power consumption during grinding can be reduced; and finally, large-dosage resource utilization of the oil shale semi-coke in the cement-based concrete is realized, and high-value resource utilization of the oil shale semi-coke is realized.

Description

technical field [0001] The invention relates to the technical field of industrial solid waste utilization, in particular to the resource utilization technology of oil shale semi-coke as a concrete material, in particular to an oil shale semi-coke adsorption inhibitor, and the invention also relates to the use of the adsorption inhibitor in concrete application in preparation. Background technique [0002] Oil shale, also known as oil mother shale, is a kind of sedimentary rock containing combustible organic matter with high ash content. It belongs to fossil fuels like coal, oil and natural gas. It is a non-renewable resource and primary energy. Oil shale will produce a large amount of by-product waste in the process of dry distillation, namely oil shale semi-coke, which is a low-quality fuel with high ash content and low calorific value, and contains water-soluble phenol, sulfide, polycyclic aromatic hydrocarbons and other toxic pollution. If not handled properly, it will c...
