Embodiment 1

[0044] The method for preparing concrete from waste glass comprises the following steps:

[0045] A. Weighing: Weigh cement, waste glass micropowder, silica fume, waste glass fine aggregate, natural coarse aggregate and water according to the mixing ratio. The mass ratio of the above components is 1:0.2:0.02:2:2.5: 0.4.

[0046] The particle size of waste glass powder is less than or equal to 0.16 mm.

[0047] The particle size of waste glass fine aggregate is less than or equal to 5mm.

[0048] The apparent density of silica fume is 24.5m 2 / g.

[0049] B. One-time stirring: mix and stir the above-mentioned silica fume, natural coarse aggregate and 50% cement with the above-mentioned 30% water, and the stirring time is 15 seconds. After fully stirring, a semi-finished concrete product is obtained;

[0050] C. Secondary stirring: put all the remaining components weighed in step A into the semi-finished concrete and stir again, the stirring time is 120 seconds, and the finish...

Abstract

The invention provides a method for preparing concrete from abandoned glass and a glass particle screening machine used in the same. The method for preparing the concrete from the abandoned glass can be used for solving the problems that the abandoned glass and concrete are not fully mixed and the abandoned glass is inconvenient to screen in the prior art. The method for preparing the concrete from the abandoned glass comprises the following steps: A, weighing; B carrying out primary stirring; and C, carrying out secondary stirring. The glass particle screening machine used in the method comprises a shell with a cavity inside, an opening is formed in the top of the shell, a detachable screening drum is arranged at the opening, the middle part of the shell is fixedly connected with a guiding cylinder in a conic cylinder shape, the larger port of the guiding cylinder is fixedly connected at the middle part in the shell, and a material channel is formed among the screening drum, the inner side of the shell and the guiding cylinder. The method for preparing the concrete from the abandoned glass has the advantages that all the components of the concrete can be fully mixed, and abandoned glass fine aggregate and abandoned glass micro powder can be stably screened by the glass particle screening machine.

Description

technical field [0001] The invention relates to a method for preparing concrete from waste glass, and a glass particle screening machine used in the preparation method. Background technique [0002] A series of waste materials such as waste concrete, waste bricks, waste sand, glass, mineral waste, etc. are used to re-mix concrete as recycled aggregate after processing. This is the main trend of the development of green concrete. The environment and the reduction of project cost and cost have great social significance, and will also play a certain role in promoting and promoting my country's sustainable development and the development strategy of building a conservation-oriented society. [0003] The development and utilization of recycled aggregate concrete in my country is later than developed countries. However, in recent years, the government has attached great importance to the recycling of construction waste. The medium and long-term social sustainable development strate...
