Abstract
The invention utilizes recycled red bricks from the process of demolishing buildings and saw dust to produce the baffle bricks with ultra low shrinkage and slight expansion property. The characteristics are that: baffle bricks are manufactured utilizing the red bricks, which are construction wastes and waste materials from demolishing of old buildings, and recycled saw dust to replace stone aggregates in traditional concrete baffle bricks; and baffle bricks manufactured by the technology of the invention are ultra low in shrinkage, while the strength and other performances are equal or slightly improved compared with the traditional baffle bricks manufactured by gravel or recycled aggregates.
Description
Technical field
The invention belongs to material of construction coagulation great soil group, relate to a kind of utilize building demolition refuse common brick with reclaim the sawdust manufacturing have unusual low-shrinkage can partition block and method of manufacture thereof.
Technical background
Along with improving constantly of rapid development of economy and people's living standard, a large amount of buildingss all will be removed in each big city every day by China, and the wood working process also produces a large amount of sawdusts.Handle demolition of buildings waste material and sawdust and become serious society and environmental problem.And seriously influence the strategy of sustainable development of country. therefore, exploitation is reclaimed and is utilized the new technology of waste material of buildings and sawdust to become more and more important.
The buildings major part that China removes at present all is a post and panel structure, and common brick accounts for 80% of material of construction total amount in the brick joisted buildings.These common bricks can be used for part through crushing and screenings and replace the natural aggregate in the concrete or be used as the road basis, and this type salvage material also is called regeneration aggregate.Aggregate of recycled concrete successful use in the building industry of American-European developed country is mainly used on the basis of non-structural concrete and road.The application of Aggregate of recycled concrete in structural concrete is limited in 20%, and the content of common brick is strict with in 5%.Mainly be that specific tenacity is lower mutually with natural stone because Aggregate of recycled concrete is with regeneration common brick aggregate, porous and higher water-intake rate, thus cause the difficult control of concrete flowability.The concrete paving block piece of mechanical pressing belongs to no slump concrete, and is less demanding to flowability, therefore, utilizes the method manufacturing concrete paving block of mechanical pressing and partition block can use 100% regeneration aggregate to replace natural gravel.
Sawdust is the wood fiber material, and its recycling mainly is in timber industry, to be used for suppressing composite wood board, but also has a large amount of quilts to topple over waste.Water-swelling is very important performance of wood fiber.
The partition block that is utilized on the domestic construction market at present mainly is common concrete brick and aerating fly ash building block etc.These products are in process of production because the bad contract with dry rate severe overweight (0.06%) that causes of quality control.The body of wall shrinkage crack will take place in general 3 to 5 years in the buildings of China at present, and major cause is that the materials for wall contract with dry rate exceeds standard.Its contract with dry rate of partition block that Aggregate of recycled concrete and regeneration common brick aggregate are made is higher than the contract with dry rate of the partition block that natural gravel is made, and this has limited the consumption of regeneration aggregate in partition block on the one hand, makes on the other hand that wall is restricted on it.Therefore, develop the new technology of making partition block security and the weather resistance that improves buildings had realistic meaning with ultralow shrinkage.
Summary of the invention
The object of the present invention is to provide a kind of concrete partition brick and method of manufacture thereof of utilizing waste material of buildings-common brick and the manufacturing of recovery sawdust to have ultralow shrinkage; Owing to used regeneration common brick aggregate and sawdust; New way is provided on the one hand the recycling of building demolition refuse-common brick and sawdust; Practiced thrift the exploitation of natural gravel on the other hand; After the 3rd partition block mixed sawdust, because its water-swelling has replenished the drying shrinkage that aquation and dehydration owing to hydraulic cementing materials cause, mechanical properties such as its intensity were constant.Therefore, the present invention is the new technology of Sustainable development.
The partition block that utilizes the present invention's technology to make;
Its starting material amount ranges is:
Cement/aggregate: 1/15～1/9;
Flyash or furnace bottom slag: 0～20% of aggregate consumption;
And the regeneration aggregate ratio is:
Regeneration common brick aggregate: 0～100%,
Or Aggregate of recycled concrete: 0～100%
Sawdust consumption: the 0.5-5% of aggregate volume amount
The consumption of water is confirmed according to actual needs.
Described cement is any cement that adopts usually in the concrete technology, comprises silicate cement, ordinary Portland cement, limestone portland cement, white cement etc.
Described flyash is all kinds of flyash that power plant discharges;
Described furnace bottom slag particle footpath＜5 millimeters;
The particle size range of described Aggregate of recycled concrete is＜40 millimeters;
The particle size range of described regeneration common brick aggregate is＜40 millimeters;
The particle size range of said sawdust is＜3 millimeters.
In the method for the present invention the water that makes with make the identical of portland cement concrete, need not specify.
In optimum implementation of the present invention, its starting material amount ranges is:
Cement/aggregate: 1/12～1/10;
Flyash or furnace bottom slag: 15% of aggregate consumption;
And, the ratio of Aggregate of recycled concrete and regeneration common brick aggregate:
Aggregate of recycled concrete: 35%, particle size range is the 20--10 millimeter
Regeneration common brick aggregate: 65% particle size range is＜10 millimeters
Sawdust consumption: the 2-3% of aggregate volume amount
Embodiment
Below, in conjunction with the practical implementation example, the present invention is done further explain.
Embodiment 1:
Can find out with the concrete partition brick characteristic of being produced that from the proportioning that table 1 is listed because the increase of common brick aggregate consumption, the intensity of partition block descends to some extent, but the intensity of all concrete partition bricks reaches more than the 15MPa still.Reached the requirement of CNS (7MPa) fully. because the contract with dry rate that has mixed the sawdust partition block is well below 0.06%.
The proportioning and the test result of table 1 concrete partition brick
Embodiment 2
The proportioning and the test result of table 2 concrete partition brick
Can find out that from the characteristic of the concrete partition brick of the listed proportioning of table 2 and manufacturing because the contract with dry rate of the increase partition block of sawdust consumption reduces, when the incorporation of sawdust surpassed 4%, partition wall changeed brick and begins to take place microdilatancy.
Embodiment 3
The proportioning and the test result of table 3 concrete partition brick
Can find out with the characteristic of the concrete partition brick of being tested from the listed proportioning of table 3, because the increase of the ultimate compression strength of the increase brick of cement consumption, and contract with dry rate increases.
