Abstract

The invention provides light-weight high-intensity waste glass ceramsite and a preparation method thereof. The light-weight high-intensity waste glass ceramsite is characterized by being prepared fromthe following raw material ingredients in parts by weight: 70 to 80 parts of waste glass powder, 15 to 25 parts of riverway silt powder, 4 to 6 parts of copper tailing powder and 1 to 2 parts of pore-forming agents. The preparation method comprises the following steps of (1) raw material preparation; (2) granulation balling; (3) microwave reinforced roasting; (4) surface reinforcing. Waste such as waste glass is used as main raw materials; the raw materials are subjected to mixing, pelleting, roasting and surface reinforcement; finally, the ceramsite with light weight and high intensity is prepared; the porosity is high; the weight is light; the tube pressure intensity is high; the softening coefficient is great; high water resistance, low water absorption rate and good particle shape arerealized; the prepared light aggregate concrete has good durability. The problem that the waste glass and the like are difficult to dispose can be effectively solved; waste materials are changed intovaluable materials; the ecological environment can be protected; in addition, the raw material resources are rich; the cost is low; the process is simple.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a light-weight and high-strength waste glass ceramsite and a preparation method thereof. Background technique [0002] Sintered ceramsite (hereinafter referred to as ceramsite) refers to a type of artificial light aggregate formed by raw material preparation, granulation into balls, preheating, high-temperature roasting, and cooling. It has light weight, high strength, good heat preservation, shock resistance, Impact resistance and other advantages. At present, light aggregate concrete produced with ceramsite has been widely used in various industrial and civil buildings, bridge load-bearing structures and civil air defense projects. According to the production raw materials, ceramsite can be divided into three categories: one is clay ceramsite, but the production and use of clay ceramsite has been banned due to excessive damage to cultivated land; the other is shal...
