Abstract
The utility model discloses an aerated concrete block made by adding steelmaking slag. The aerated concrete block made by adding the steelmaking slag comprises a block body, wherein a plurality of through holes with a diameter of 5-10 millimeters are arranged on the block body. The through holes penetrate though an upper surface of the block body and a lower surface of the block body and are arranged interlacedly. Two end faces of the block body are used for connection, wherein one end face of the block body is provided with a protruding tenon, and the other end face of the block body is provided with a groove for placing the protruding tenon. Steelmaking slag is added into raw materials for making the aerated concrete block, so comprehensive utilization of the steelmaking slag is achieved and energy conservation and emission reduction are also achieved; due to the steel making slag, the coefficient of thermal conductivity of the aerated concrete block is reduced, and heat preservation and insulation performance is improved, and therefore the aerated concrete block has a good energy-saving effect; and the aerated concrete blocks are prone to connection, so gaps formed in vertical mortar joints between the aerated concrete blocks are prevented.

Technical field
The utility model relates to building materials field, is specifically related to a kind of air-entrained concrete building block that steel-making waste residue is processed that adds.
Background technology
Autoclaved aerated concrete blocks is to make air entrained agent with adding aluminium powder in the batching of calcareous material (like cement, lime) and siliceous material (like sand, flyash); Through adding water stirring, moulding by casting, expansions of getting angry, precuring cut; The porous silicate building block that forms through steam curing at high pressure again, current Autoclaved aerated concrete blocks product is the important raw and processed materials of domestic various high-storey building frame structures.It has in light weight, good heat insulating, has workability and incombustible advantage.
The coefficient of thermal conductivity of existing Autoclaved aerated concrete blocks is 1/4th to 1/5th of loam brick and a sand, if can further reduce its coefficient of thermal conductivity, improves its thermal and insulating performance; Thickness with regard to the further attenuate body of wall of ability; The corresponding effective usable floor area that just enlarges building is practiced thrift constructional materials thickness, improves efficiency of construction; Reduce construction costs, alleviate the building deadweight.In addition; Existing Autoclaved aerated concrete blocks is in work progress; Because the building block joint face is more smooth, insert the mortar that building block vertically connects seam and can sink because of deadweight, be difficult to guarantee closely bonding of vertical mortar joint mortar; Vertical mortar joint of blockhouse is prone to problems such as space, printing opacity, bonding force difference, can produce quality problems such as bonding not firm, the seepage of longitudinal crack, the mortar of body of wall.
Nowadays the slag that existing steel mill steel-making back generates generally adopts the waste method, pours slag into slag ladle (dish) exactly, after slow cooling, directly ships by rail and abandons down to the slag field at present.This method is that the method that has just adopted since the steel and iron industry is arranged, and Chinese most steel mills still continue to use this kind technology.The processing method of above-mentioned this slag, not only technology investment is big, takes up an area of extensively, and equipment is many, and does not have utilize resources synthetically, does not realize the purpose of energy-saving and emission-reduction.
Summary of the invention
The utility model technical problem to be solved is: the air-entrained concrete building block that provides a kind of adding steel-making waste residue of novel structure to process, realized the comprehensive utilization of steel-making waste residue, and accomplished the purpose of energy-saving and emission-reduction; Further reduce coefficient of thermal conductivity, improved thermal and insulating performance, had higher energy-saving effect; Be easy between the building block connect, avoided vertically the space occurring in the mortar joint between the building block.
For solving the problems of the technologies described above, the technical scheme of the utility model is: add the air-entrained concrete building block that steel-making waste residue is processed, comprise block body, wherein:
Said block body is provided with the through hole that several diameters are 5～10mm, and said through hole runs through the upper surface and the soffit of said block body, and the setting that is staggered of said through hole;
Two end faces that are used for connecting of said block body, end face is provided with the tenon of protrusion therein, and another end face is provided with the groove that is used for ccontaining tenon.
As a kind of optimized technical scheme, said block body is provided with 3 exhausting holes, and adjacent two exhausting holes are crisscross arranged.
As a kind of optimized technical scheme, the cross section of said tenon is trapezoidal.
As a kind of optimized technical scheme, the specification of said block body is 600X240X240mm, 600X240X200mm, 600X240X180mm or 600X240X120mm.
After having adopted technique scheme, the beneficial effect of the utility model is:
1. because the air-entrained concrete building block of the utility model has added steel-making waste residue in its raw material, comprise steel slag tailing slurry and refining lime mud, turn waste into wealth, realized the comprehensive utilization of steel-making waste residue, accomplished the purpose of energy-saving and emission-reduction.
2. because the utility model block body is provided with the through hole that several diameters are 5～10mm, this through hole runs through the upper surface and the soffit of block body, and the setting that is staggered.The design of through hole has further reduced the coefficient of thermal conductivity of air-entrained concrete building block, has improved its thermal and insulating performance, has higher energy-saving effect.
Since the utility model at two end faces that are used for connecting of block body, end face is provided with the tenon of protrusion therein, another end face is provided with the groove that is used for ccontaining tenon.Two building blocks of butt joint plug together through tenon and groove each other, can avoid connecting seam and space, printing opacity occur, and the frictional force between tongue-and-groove also improves the bonding force of mortar and blockhouse.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the sectional view of Fig. 1.
Among the figure: 1. block body, 2. through hole, 3. tenon, 4. groove.
The specific embodiment
Shown in Fig. 1 and Fig. 2 are common, a kind ofly add the air-entrained concrete building block that steel-making waste residue is processed.Its processing technology is: with lime, cement, flyash; And steel slag tailing slurry and refining lime mud are done raw material; In above-mentioned raw materials, add aluminium powder and make air entrained agent, through adding water stirring, moulding by casting, expansions of getting angry, precuring cutting, pass through steam curing at high pressure again and form.With the raw material that steel-making waste residue is produced as building block, turn waste into wealth, realized the comprehensive utilization of steel-making waste residue, accomplished the purpose of energy-saving and emission-reduction.
