Abstract
The invention discloses a special masonry binder for autoclaved aerated concrete, and belongs to the technical field of building materials. The binder is characterized in that water and a dry material are mixed at a mass ratio of 1:4 and mixed for 3-5min to form mortar, wherein the dry material comprises the following components by mass percentage: 20-40% of cement, 25-40% of 40-70-mesh quartz sand, 30-45% of 80-140-mesh quartz sand, 2-6% of 200-mesh heavy calcium powder, 1.5-5% of dispersible latex powder and 0.15-0.5% of water-retaining agent. The special masonry binder for the autoclaved aerated concrete is prepared by taking the 40-70-mesh quartz sand, the 80-140-mesh quartz sand, the cement and the heavy calcium powder as main raw materials and adding the water-retaining agent and the dispersible latex powder. As the binder is not absorbed too quickly by the autoclaved aerated concrete, the binding strength is not lost, the binder is not stripped or damaged under the common bearing stress, hollowing and cracking can be prevented, and various requirements of construction can be met.
Description
Technical field
Binding agent is built in a kind of steam-pressing aero-concrete special use by laying bricks or stones, belongs to building material technical field, is specifically related to a kind of binding agent of building by laying bricks or stones of the steam-pressing aero-concrete special use take quartz sand and suitable consolidating material as main raw material(s) production.
Background technology
Along with the global performance source problem becomes clear day by day, country's carrying forward vigorously in energy-saving and emission-reduction and walling innovation work, the house wall power saving more and more is subject to the close attention of the whole society, development is green, the Novel environment-protective energy-saving materials for wall is imperative, at present, China has proposed renewal, higher requirement at construction material, and traditional clay brick masonry replaces by blockworks such as steam-pressing aero-concretes.
Steam-pressing aero-concrete is a kind of of gas concrete, to make airentraining agent with adding aluminium powder in the batching of calcareous material (such as cement, lime) and siliceous material (such as sand, flyash, slag), through add water stirring, casting, the expansion of getting angry, precuring cutting, the porous silicate building block that forms through autoclave curing again.The unit weight of steam-pressing aero-concrete is 1/3rd of clay brick, and heat-insulating property is 3 ~ 4 times of clay brick, and sound-proofing properties is 2 times of clay brick, and anti-permeability performance is more than a times of clay brick, and fire performance is 6 ~ 8 times of Steel Concrete.Autoclave aerated concrete building block is the new construction material that a kind of state key is promoted, and has a series of superior performances such as lightweight, insulation, heat insulation, antidetonation.
But because steam pressurized foam concrete water absorbent surface speed is fast, when especially in its production process, cutting, the goods that cutting is broken easily form chip and stick to the surface, when common masonry mortar is put on product surface, moisture in the mortar is very easily absorbed by the fast goods of suction, cause reducing the mortar joint cohesive strength, shear strength and the construction quality of masonry have been reduced, affected promoting comprehensively of wall innovation work, as seen because these novel wall materials of steam-pressing aero-concrete have many singularity that is different from clay brick, also must there be the binding agent of building by laying bricks or stones that adapts with it to build by laying bricks or stones as masonry structure, to guarantee the quality and safety of Novel wall structure, for above situation, the many enterprises of recent year and research institutions develop this and innovate, also formed the product of various prescriptions, the domestic national sector standard JC890-2001 that also worked out of while, yet domestic many quality producies are uneven, do not have good specific aim and practicality, for the quality of better guaranteeing adhesive special and keep good water-retentivity, cohesiveness the invention provides a kind of steam-pressing aero-concrete special use and builds binding agent by laying bricks or stones.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provide a kind of synchronous with the steam-pressing aero-concrete distortion, binding agent is built in a kind of steam-pressing aero-concrete special use that cohesiveness is strong by laying bricks or stones.
The technical solution adopted for the present invention to solve the technical problems is: binding agent is built in a kind of steam-pressing aero-concrete special use by laying bricks or stones, it is characterized in that: add entry according to quality than water: siccative=1:4 and stir 3 ~ 5min mortar processed; Described siccative mass percent is: cement 20 ~ 40%, 40 ~ 70 order quartz sands, 25 ~ 40%, 80 ~ 140 order quartz sands, 30 ~ 45%, 200 order dicalcium powders 2 ~ 6%, polymer dispersion powder 1.5 ~ 5%, water-holding agent 0.15 ~ 0.5%.
Preferably, described cement is normal silicate 42.5 cement.
Described quartz sand silt content is less than 2%.
Preferably, described water-holding agent is Vltra tears.
Binding agent adds entry according to quality than water: siccative=1:4 again and stirs 3 ~ 5min mortar processed in use first the siccative mixing.
Aggregate of the present invention adopt the inclusion-free silt content less than 2% quartz sand as aggregate, its preferably aggregate collocation forms good skeleton in binding agent, can access workability good closely knit build binding agent by laying bricks or stones.Polymer dispersion powder among the present invention is used for boning in binding agent, obtains preferably cohesive strength to guarantee binding agent.Water-holding agent among the present invention (Vltra tears) is used for carrying out water-keeping thickening in binding agent, improve the wet viscosity of construction simplicity and binding agent etc.Adopt normal silicate 42.5 cement among the present invention, be used for regulating the time of coagulation of binding agent and guarantee good later strength.Dicalcium powder among the present invention not only can reduce cement consumption and reduce production costs, and can also increase toughness and the intensity of binding agent.
The present invention utilizes the binding agent of building by laying bricks or stones of steam-pressing aero-concrete special use that quartz sand and suitable consolidating material make for main raw material(s), fast for steam pressurized foam concrete water absorbent surface speed, the characteristics that chip adheres to, by the fineness ratio increase of regulating quartz sand build by laying bricks or stones binding agent with and the consistency of concrete chip, and interpolation optimum quantity polymer dispersion powder and water-holding agent, make the binding agent of building by laying bricks or stones of the present invention when effectively resisting the aerated concrete products water absorbent surface, guarantee the cohesiveness of self, guarantee the mortar joint cohesive strength of aerated concrete products.
Compared with prior art, the beneficial effect that binding agent has is built in a kind of steam-pressing aero-concrete special use of the present invention by laying bricks or stones: the present invention be directed to the strong absorptive of steam-pressing aero-concrete and make, has good water-retentivity to guarantee that thereby the moisture in the binding agent can be by the too fast absorption forfeiture of steam-pressing aero-concrete cohesiveness intensity, firmly make it have good cohesiveness with basic unit bonding, can stripping damage under common carrying stressing conditions, stop the generation of hollowing cracking, satisfy the requirements of construction, and has a good anti-slipping property, good workability and constructing operation accessibility, can guarantee to construct comfortable full of mortar.The significant advantages such as the present invention has energy-saving and environmental protection, intensity is high, the construction comprehensive cost is low, good product quality.The present invention builds binding agent by laying bricks or stones and is fit to large-scale promotion application, has significant economic benefit and social benefit.
