Abstract
The present invention provides a reinforced masonry micro foam self expending type pouring mortar and a manufacturing method thereof and an application method thereof. Ordinary mortar is used, an expanding agent made from aluminum oxide, limestone, calcium sulphate, alum stone, calcium hydroxide and phosphate are added to the ordinary mortar, and the manufactured mortar can be poured and completed with a simple method without influencing engineering quality. The pouring mortar overcomes the defects of poor placeability, low strength, etc. of the ordinary mortar, and has the advantages of strong self expansibility and good mechanical performance. The cohesive force of masonry and steel bars, the crack resistance, the seepage resistance and the insulating property of the building body can be effectively increased.
Description
Technical field
The present invention relates to material of construction, especially steel bar reinforced building block micro foam self expending type pouring mortar.
Background technology
Reinforced masonry is the very promising novel building structure formation of a kind of tool in China; it has draws materials conveniently; changing waste into valuables; the holllow building block (as concrete segment, fly ash hollow building block etc.) that both available various non-agglomerated material is made; the substitute for clay vitrified brick; save energy; protect the fields and ecotope; simultaneously, owing to the masonry configuration reinforcement, improved the stress performance of non-reinforced masonry; so; can make many, the Highrise buildings of such structure building, and expense economizes more than skeleton construction, construction is also convenient.
But, for a long time, because the masonry mortar of pouring mortar that uses and masonry is basic identical both at home and abroad, mostly by common masonry cement, building sand, granule is through rubble, water is through mixing, stirring forms, in actual use and scleroma process afterwards, there are many problems, mainly show as: 1. the pre-dabbling clean and tidy degree of having inserted the hole of reinforcing bar is had relatively high expectations, owing in the masonry building process, inevitably foreign material such as masonry mortar can be dropped or adhere in the hole, if it is not removed clean, then inevitably influence the bond quality of reinforcing bar and masonry, thereby influence the stress performance of structure; As if building height by laying bricks or stones than then removing foreign material difficulty further after big, highly less as if building by laying bricks or stones, then influence construction speed; 2. because due to the characteristic of general masonry mortar material itself, in the mortar injection process of setting, can shrink phenomenon, produce the crack, cause reinforcing bar highly to produce the different crack of degree along it inevitably, seriously reduce the cohesive force of masonry and reinforcing bar, the drawbacks such as structure properties reduction of reinforced masonry with masonry or reinforcing bar; 3. because general masonry mortar is relatively poor as the workability of pouring mortar, time of coagulation is short, and simultaneously because the area of holllow building block hole own is less, in fact reason such as be difficult to that shake is smash causes pouring quality, density relatively poor, is easy to generate the cellular cavity phenomenon.If improve the workability of pouring mortar, the water cement ratio that then causes mortar easily is excessive and produce serious segregation phenomenon, influences construction quality equally.
The mid-1970s, Jiangsu Province's building scientific research adopt cement 85-88%, alumina 6-7.5%, gypsum about 6%, and preparation produces expansive concrete, because the material price height, transportation is inconvenient, has influenced and has promoted the use of.Only the swelling agent of being produced by Japan all needs high-temperature calcination, and both the highly energy-consuming source was uneconomical again.
Summary of the invention
The present invention is exactly in order to overcome the shortcoming of prior art, to provide a kind of self-expanding good, good stress performance is arranged, reinforced masonry little foam self-expanding pouring mortar and manufacture method and using method that construction is simple, convenient, economical.
For realizing purpose of the present invention, adopt following technical scheme:
A kind of steel bar reinforced building block micro foam self expending type pouring mortar, through rubble, natural water constitutes its main ingredient, comprises also in its component that self-expanding agent, its content are 8-15% by common masonry cement, building sand, granule;
Described self-expanding agent by by aluminum oxide and Wingdale high temperature sintering and the calcium aluminate clinker, calcium sulfate, alunite, calcium hydroxide, the phosphoric acid salt that form form, each set of dispense ratio is:
Aluminum oxide: 20-40%
Wingdale: 30-50%
Calcium sulfate: 20-40%
Alunite: 8-25%
Calcium hydroxide: 0-20%
Phosphoric acid salt: 0-20%.
The manufacture method of steel bar reinforced building block micro foam self expending type pouring mortar is, at first with the high-temperature calcination according to a certain ratio of aluminum oxide, Wingdale, wherein the proportioning of aluminum oxide is 20-40%, the proportioning of Wingdale is 30-50%: its sinter mixes according to a certain ratio, grinds with calcium sulfate, alunite, calcium hydroxide, phosphoric acid salt then, generate the self-expanding agent, wherein proportioning is calcium sulfate: 20-40%, alunite: 8-20%, calcium hydroxide: 0-20%, phosphoric acid salt: 0-20%; Again the self-expanding agent is joined by common masonry cement, building sand, granule in the ordinary mortar that rubble, natural water constitute by proportioning, blending, stirring.
The using method of steel bar reinforced building block micro foam self expending type pouring mortar is to be realized by following steps:
1. build the holllow building block masonry by laying bricks or stones;
2. the hole that desire is rotated reinforcing bar is cleaned out;
3. reinforcing bar is set, and fixing;
4. the steel bar reinforced building block micro foam self expending type pouring mortar that stirs is poured into;
5. suitably tamping.
Mortar provided by the present invention, it is a kind of mortar that vertical reinforced masonry perfusion is used that is specially adapted for, owing to added special self-expanding agent, so having, such pouring mortar draws materials conveniently, self-expanding is good, workability is good, to the less demanding advantage of execution conditions, finish in perfusion, behind the mortar scleroma end of processing, can produce force value about 0.5MPa to reinforcing bar and hole inwall, use different compound methods, can make to produce no foam or little foam in the pouring mortar, produce evenly small discontinuous micropore in the mortar thereby make, make masonry have heat insulation function, thereby improved the cohesive force and the cracking resistance of masonry and reinforcing bar effectively, impervious, heat-insulating property.Remove all drawback of general masonry mortar, improve effectively and join the stress performance and the construction quality of building masonry as pouring mortar.
The invention will be further described below in conjunction with drawings and Examples.
