Embodiment 1

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

[0045] A. Weighing: Weigh cement, waste glass powder, 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 the waste glass powder is less than or equal to 0.16 mm.

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

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

[0049] B. One-time mixing: Mix the above weighed silica fume, natural coarse aggregate and 50% cement with the above weighed 30% water, and the mixing time is 15 seconds. After full mixing, a semi-finished concrete product is obtained;

[0050] C. Secondary mixing: Put all the remaining components weighed in step A into the semi-finished concrete product for mixing again, the mixing time is 120 seconds, and the finished concrete is obtained...

Embodiment 2

[0061] The method for preparing concrete from waste glass includes the following steps:

[0063] The particle size of the waste glass powder is less than or equal to 0.16 mm.

[0064] The particle size of the waste glass fine aggregate is less than or equal to 5 mm.

[0065] The apparent density of silica fume is 24.5m 2 / g.

[0066] B. One-time mixing: Mix the above weighed silica fume, natural coarse aggregate and 50% cement with the above weighed 30% water for a mixing time of 60 seconds. After fully mixing, a semi-finished concrete product is obtained;

[0067] C. Secondary mixing: Put all the remaining components weighed in step A into the semi-finished concrete product for mixing again, the mixing time is 180 seconds, and the finished concrete is obtaine...

Embodiment 3

[0069] The method for preparing concrete from waste glass includes the following steps:

Abstract

The invention provides a glass particle screening machine. The problems that existing waste glass concrete is mixed insufficiently, and waste glass is not convenient to screen are solved. The glass particle screening machine comprises a shell with a cavity in the interior. An opening is formed in the top of the shell, and a detachable screen drum is arranged at the opening. The middle of the shell is fixedly connected with a guide drum in a conical drum shape, a large end opening of the guide drum is fixedly connected to the middle in the shell, and a material passing channel is formed among the screen drum, the inner side of the shell and the guide drum. According to a preparing method, all components of concrete can be sufficiently mixed, and meanwhile the screening machine can stably screen out waste glass fine aggregate and waste glass micropowder.

Description

Technical field [0001] The invention relates to a method for preparing concrete from waste glass, and a glass particle sieving machine used in the above preparation method. Background technique [0002] A series of waste materials such as waste concrete, waste bricks, waste sand, glass, and mineral waste are used to remix concrete as recycled aggregate after processing. This is the main trend in the development of green concrete, which is important for energy conservation and protection. The environment and the reduction of project costs and costs are of 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 that in developed countries. However, in recent years, the government has attached great importance to the recycling and reuse of constru...
