Problems solved by technology

Compared with developed countries, China started late, and the comprehensive utilization rate of resources is low. A large amount of waste glass has not been effectively recycled and utilized. Since waste glass is a non-biodegradable material, it is difficult to pass through natural circulation and general physical and chemical methods. It is not a good solution to deal with and decompose it, and landfill it will not only occupy land resources but also cause damage to the ecological environment

Abstract

The invention discloses a method for improving the hydration activity of waste glass powder. The method comprises the following steps: carrying out cleaning, airing, preliminary crushing and jaw crushing on waste glass having different colors and kinds, collected from salvage stations, and carrying out ball milling by a ball mill for 60-120 min to obtain the waste glass powder; carrying out dry screening, wet screening and a settlement process on the waste glass powder to obtain waste glass powder with the particle size range of 10-75 [mu]m and the particle specific surface area being greater than 400 m<2> / kg; and adding cement and a composite exciter to the waste glass powder, carrying out mixing milling treatment for 30 min, adding water, pouring the obtained mixture into a cement neat paste stirrer, and stirring the mixture for 2-3 min to obtain a composite gelling material. The composite gelling material prepared in the invention is a waste glass recycled product, waste glass has a high utilization rate, wide sources and easiness in obtaining, and the composite gelling material has the advantages of quickness in setting, quickness in hardening, high early stage strength, and great increase of the later strength.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a method for improving the hydration activity of waste glass powder. Background technique [0002] With the continuous development of economy and industry and the improvement of people's living standards, glass has been widely used in many fields such as construction, equipment, scientific research, chemical industry and daily life. At the same time, the output of waste glass is also increasing. According to statistics from the United Nations, 7% of global industrial waste is waste glass. In 2010, the United States produced about 11.5 million tons of waste glass, with a recycling rate of 27%. 3%-5%, and the utilization rate is only 13%. The annual output in Hong Kong is about 137,000 tons, 96.7% of which is disposed of in landfills, while the glass utilization rate in many European countries exceeds 60%, of which Germany and Switzerland have exceeded 90%. Compared wit...
