Steel tube glass concrete component

Abstract

The invention relates to a composite tube, and in particular relates to a steel tube glass concrete component of composite tubes. The steel tube glass concrete component comprises a steel tube, wherein the steel tube is filled with glass concrete. The steel tube glass concrete component has the beneficial effects that by applying the waste glass into the steel tube concrete, on one hand, the steel tube provides a tightening force for the glass concrete, so that the defect that the glass concrete is swelled and cracked because of alkali-silicon acid reaction is overcome; and on the other hand, the core concrete generates shrinkage stresses of different degrees, therefore, the concrete is cracke;, however, the solving method at present is generally to add a swelling agent into the steel tube concrete to compensate the shrinkage stress of the core concrete, and in the glass concrete, the shrinkage stress of the concrete can be compensated by the glass concrete swelling force caused by the alkali-silicon acid reaction to a certain extent, thereby being beneficial for bringing the potential advantage of the waste glass into play.

Description

technical field [0001] The invention relates to a composite pipe, in particular to a steel pipe glass concrete member in the composite pipe. Background technique [0002] For a long time, my country's economic development model has been resource-consuming. In addition, my country is in a period of vigorous economic development, and industrial production will produce more and more solid waste—waste glass, waste rubber, and municipal solid waste incineration ash. Therefore, , Recycling these solid wastes has important practical significance for resource conservation and environmental protection in our country. [0003] In recent years, with the continuous development of my country's economy, glass has been more and more used in people's production and life. At the same time, along with industrial production and people's life, more and more waste glass has been produced. According to the survey, my country's annual waste glass is more than 2 million tons, and the recycling rate...

Problems solved by technology

One of the most important problems in the application of waste glass in concrete is the alkali-silicic acid reaction, which leads to cracking of concrete, which hinders the application of waste glass in concrete.
