Abstract
The invention discloses a high-strength sand aerated concrete block produced from sewage treatment plant sludge hydrolysis residue and a production method thereof; the block is characterized by comprising the following materials in percentage by weight: 30 to 60 percent of sludge hydrolysis residue, 0.2 to 0.7 percent of aluminum paste, 20 to 50 percent of quartz sand, 10 to 20 percent of cement, 5 to 17 percent of lime, and 0.8 to 1.5 percent of plaster; and in addition, water is added in, and the amount of the water added in is 10 to 40 percent of the total amount of the materials in percentage by weight. The materials in the invention are added with water to be uniformly stirred and mixed and cured by steam to prepare the finished product. The product of the invention can be used for the exterior wall and the bearing wall of a frame structure, makes full use of the sewage treatment plant sludge hydrolysis residue waste, is beneficial to environment protection, and reduces the production cost.
Description
Technical field
The present invention relates to mud, add mixed building block of production high strength aerating and production methods thereof such as quartz sand with existence in the city domestic sewage processing.
Background technology
There are a large amount of mud in city domestic sewage in handling, and contains a large amount of organism, causes secondary pollution.
On open was 2007.08.08, publication number is CN101012118, application number is in 200710051490.8 the Chinese patent application specification sheets, a kind of method of producing gas concrete with sludge hydrolytic residue is disclosed, a kind of method of producing gas concrete (also being building block or foamed brick) with sludge hydrolytic residue of wastewater treatment factory has been proposed, gas concrete contains following component (weight ratio): sludge hydrolytic residue 20～50%, aluminium powder cream 2～10%, flyash 35～65%, cement 10～20%, lime 4～15%, gypsum 1～1.5%, other adds 10%～50% comprehensive water of above-mentioned each component.Production technique is: the weighing each component, and mix and stirred 5～30 minutes, import mould molding, vapor cure, P=0.8～1.0Mpa, goes out the modulo n check warehouse-in at 2～3 hours time.Because one of main raw material that this method is used is a flyash, and vapor cure pressure is low in the production process, the steam-cured time is short, makes that the block strength of its production is limited, and maximum intensity can only reach 3.0～3.5Mpa.
Intensity is the key index that materials for wall is estimated the goods inner quality, is mass property check item of the utmost importance, is the essential condition of structural bearing.Its intensity height directly influences the degree of safety and the anti-seismic performance of building structure, is related to the safety of people's lives and properties.Therefore, national standard is very strict to this performance index regulation.Brick and piece series products all adopt the ultimate compression strength of goods to come the assessment intensity grade usually, with the entire compression strength level of every batch of goods of mean compressive strength control, the dispersion degree of controlling every batch of goods with compressive strength standard value or ultimate compression strength minimum value must not be above the load bearing requirements of building structure.Therefore, the building block that can only reach 3.0～3.5Mpa of above-mentioned maximum intensity can only be used for interior wall, the infilled wall of buildings.And, just can not use that (the building block desired strength of kitchen, toilet is as more than the 5.0MPa, and the exterior wall desired strength reaches more than the 6.0MPa for the higher kitchen of requirement of strength, toilet, exterior wall etc.)。
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, a kind of high-strength sand aerated concrete block and production method thereof of producing with the sewage treatment plant sludge hydrolysis residue is provided, in order to solve the reluctant difficult problem of sludge of sewage treatment plants hydrolytic residue, reach utilization of waste material, reduce the purpose of polluting, reduce the cost, make things convenient for production management, simultaneously, make the ultimate compression strength of its product can satisfy the requirement of building bearing wall.
Technical solution problem of the present invention adopts following technical scheme:
The gas concrete that the present invention produces with sludge hydrolytic residue in the sewage work is characterized in:
Material by weight percentage constitutes:
Sludge hydrolytic residue: 30～60%; Aluminium powder cream: 0.2～0.7%; Quartz sand: 20～50%;
Cement: 10～20%: lime: 5～17%; Gypsum: 0.8～1.5%;
Other adds water, and by weight percentage, the water yield of adding is 10%～40% of a material total amount.
The production method that the present invention produces gas concrete with sludge hydrolytic residue in the sewage work is characterized in carrying out as follows:
1,, and is equipped with water according to quantity by each component in the proportioning weighing material;
2, it is bad all each components and water to be added jointly stirrer, and the stirring through 6～8 minutes mixes and is blank;
3, the described blank of step 2 is imported mould, and cut into block base;
4, with the described block base of step 3 with vapor cure, vapor pressure P is 1.2～1.35Mpa, temperature is 195 ℃～200 ℃, curing time is 8～9 hours; Finish depanning after the maintenance.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention makes full use of the sludge hydrolytic residue of wastewater treatment factory waste, and utilization of waste material is environmental, has reduced the production cost of factory.
2, one of main raw material(s) of the present invention is a quartz sand, the mixture intensity of learning quartz sand and cement through practice is higher, and building block vapor pressure in process of production can reach 1.2～1.35Mpa, temperature at 195 ℃～200 ℃, thereby makes product strength want high a lot of than the fly ash building block equal strength.
3, the present invention is with vapor cure, enough for a long time fully maintenance make its product after vapor cure, need not to hang can directly to use, the ultimate compression strength of product can reach more than the 6.0Mpa, can satisfy the requirement of the ultimate compression strength of the exterior wall of skeleton construction and bearing wall.
