The building solid wastes are accumulated in a large quantity, so that the building solid wastes not only occupy the land, but also have serious influence on the surrounding environment, even bring about surrounding areas, and if the building solid wastes are not treated effectively in time, the ecological environment is irreversibly damaged.
The building solid wastes are accumulated for a long time and cannot be effectively treated, so that influence is brought to the life of citizens, and more pollution hidden dangers are buried in urban environments. It is known that in recent years, due to lack of a unified and perfect construction solid waste management method and a standardized disposal place, a large amount of construction solid waste in cities is simply disposed of by discarding, landfilling and the like. However, the building glue, paint, lacquer and the like in the solid waste of the building belong to high polymer materials which are difficult to degrade, and contain harmful heavy metal elements, and the heavy metal elements are buried underground to pollute underground water and directly endanger the life of surrounding residents.

Detailed Description
The following describes the embodiments of the present invention further:
the non-standard seepage-proofing hollow brick prepared based on building solid waste comprises the following raw materials: building solid waste, cement, sand, water and cement-based permeable crystallization waterproof agent; the nonstandard impermeable hollow brick with the strength mu5.0 is prepared, and the weight of each component of the raw materials is shown in the table I (kg/m 3 )：
List one
The non-standard seepage-proofing hollow brick prepared based on building solid waste comprises the following raw materials: building solid waste, cement, sand, water and cement-based permeable crystallization waterproof agent; the nonstandard impermeable hollow brick with the strength mu3.0 is prepared, and the weight of each component of the raw materials is shown in the table II (kg/m 3 )：
Watch II
The building solid waste in the two non-standard seepage-proofing hollow bricks is masonry, hardened concrete and mortar. The cement is the ordinary Portland cement P.O grade 42.5, and the cement consumption is not less than 10% and not less than 250kg/m of the solid waste weight of the building 3 . The sand is made of limestone, the fineness modulus Mk=2.6, the mud content is less than or equal to 3%, and the mud block content is less than or equal to 1%.
The preparation methods of the two non-standard seepage-proofing hollow bricks are the same, and the specific preparation steps are as follows:
(1) Collecting building solid waste, and grinding by a grinding machine, wherein the particle size of the ground building solid waste is less than or equal to 9.5mm;
(2) Cement, sand, water and cement-based penetrating crystallization waterproof agent are added into the ground building solid waste according to the formula ratio, and stirring is carried out by a forced stirrer for more than or equal to 180 seconds.
(3) The stirred mixture is sent to a brick making machine to be pressed into non-standard seepage-proof hollow bricks.
(4) The pressed nonstandard impermeable hollow bricks are stored in the open air, the surfaces of the nonstandard impermeable hollow bricks are covered with plastic films, and watering is carried out to keep the surfaces warm and moist, and natural maintenance is carried out. Watering is preferably carried out for 4-6 times per day under the normal temperature condition; when the temperature is higher than 30 ℃, watering is preferably added for 1-2 times; when the air temperature is lower than 5 ℃, watering is not suitable; natural curing is more than or equal to 28 days.
The preparation method can be used for preparing 390 multiplied by 175 multiplied by 190 of the double-row-hole nonstandard impermeable hollow bricks and 190 multiplied by 175 multiplied by 190 of the single-row-hole nonstandard impermeable hollow bricks, can be used for building inner and outer walls of a building, reduces the purchase of building materials, and saves the cost.
When the non-standard impermeable hollow brick prepared by adopting the cement-based permeable crystalline waterproof agent is used for building an outer wall of a building, when water is permeated into the surface of one side of the outer wall, the active chemical substances of the cement-based permeable crystalline waterproof agent contained in the non-standard impermeable hollow brick permeate into the outer wall and the brick ribs of the non-standard impermeable hollow brick by taking water as a carrier and react with cement hydration products to generate needle-shaped crystals which are insoluble in water so as to fill micro gap channels of the outer wall and the brick ribs of the hollow brick, thereby playing a role of automatically making up water blocking. Meanwhile, the waterproof wall has lasting crystal growth capability, can be re-activated when meeting water again, and can be chemically reacted again to repair microcracks, so that the waterproof capability can be maximized due to the fact that the waterproof performance is increased along with time, and the effects of preventing moisture and leakage of the wall are achieved.
When the nonstandard seepage-proofing hollow brick with the hollow brick strength mu5.0 is prepared, the weight percentage range of the cement-based seepage-proofing crystalline agent is controlled to be 0.19-0.2. When the nonstandard seepage-proofing hollow brick with the hollow brick strength Mu3.0 is prepared, the weight percentage range of the cement-based seepage-proofing crystalline agent is controlled to be 0.126-0.132. When the cement-based penetrating crystallization waterproof agent is added too low, the dampproof and seepage-proof requirements of the nonstandard seepage-proof hollow bricks are reduced; when the addition is too high, the preparation cost increases.
The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the specific details of the above embodiments, and various simple modifications can be made to the technical solution of the present invention within the scope of the technical concept of the present invention, and all the simple modifications belong to the protection scope of the present invention. In addition, the specific features described in the above embodiments may be combined in any suitable manner, and in order to avoid unnecessary repetition, various possible combinations are not described further. Moreover, any combination of the various embodiments of the invention can be made without departing from the spirit of the invention, which should also be considered as disclosed herein.
