Problems solved by technology

The practice of a large number of civil engineering projects at home and abroad has proved that the use of light, high-strength light aggregate and engineering optimization design can reduce the infrastructure and construction funds of bridges and high-rise buildings, and the building energy-saving benefits are significant. However, my country's current application The lightweight aggregates of lightweight high-strength concrete, especially the manufacturing technology of lightweight high-strength ceramsite is still in the development stage, and the product performance and quality technical indicators cannot meet the needs of development

Embodiment 1

[0035] Table 1 shows the chemical composition analysis results of the clay shale used to produce high-strength or ultra-light ceramsite according to the present invention.

[0036] Element

[0037] The clayey shale described in Embodiment 1 has many kinds in the concept of geology, and the clayey shale used in the present invention is defined from the perspective of the characteristics used for the production of expanded ceramsite. Shale can be divided into two categories: swellable shale and non-swellable shale under the technical conditions of calcination of expanded shale ceramsite. The shale used in the present invention belongs to swellable clayey shale.

Abstract

This invention discloses a method for producing shale ceramic granules for lightweight concrete. The method comprises: crushing waste clay shale as the raw material, and sintering without additive or granulating to obtain shale ceramic granules. The method utilizes instant expansion technique to shorten preheating and sintering time, lower preheating and sintering temperature, and save energy. The obtain shale ceramic granules can be used as light aggregate for lightweight and high-strength concrete.

Description

Technical field: [0001] The invention relates to a concrete building material, in particular to a manufacturing process of concrete light aggregate. Background technique: [0002] At present, the area of ​​buildings built in my country every year is as high as 1.6 billion to 2.1 billion m 2 , but more than 95% of new buildings are still high-energy-consuming buildings, and the heating energy consumption per unit building area is about three times that of developed countries with similar climates. my country's building energy consumption has accounted for nearly 30% of the country's energy consumption. Building energy efficiency has become a major problem. [0003] In recent years, my country's urban buildings tend to be high-rise, and urban traffic develops to three-dimensional traffic to save land area and improve traffic congestion. The practice of a large number of civil engineering projects at home and abroad has proved that the use of light, high-strength light aggreg...
