Description
Technical field
The invention belongs to building material field, being specifically related to a kind of Seismic Isolation of Isolation Layer mortar for building by laying bricks or stones between country building superstructure and basis and preparation method thereof.
Background technology
Mortar, as a kind of civil engineering material, is widely used in building by laying bricks or stones, plasters or in decorative engineering in civil construction.Its main raw material is cement, sand, water and other admixture.
The principle of base isolation is to set up the very little supporting member of horizontal rigidity between basis and superstructure; the natural period of vibration of superstructure is extended; away from the predominant period of earthquake action; thus reduce earthquake action to the impact of superstructure; alleviate earthquake calamity, the safety of life and property of protection people.Although Base Isolation Technology obtains application in Highrise buildings, and has occurred various structures form, in all previous earthquake, play shock absorbing Function of reducing disaster well.But because its cost is high, complicated construction technique, is thus not suitable for promoting in the low rise buildings of villages and small towns.And in actual seismic, the damage situations of country building is the most serious often.
Therefore, research and develop a kind of shock insulation form that is economical and practical, cheap, easy construction, for quake evaluation, there is very important practice significance and social economic value.
Summary of the invention:
The object of the invention is to seek a kind of intensity be suitable for, Seismic Isolation of Isolation Layer based on the mortar that anti-shear performance is good, is applied in country building, weak to solve country building anti-seismic performance, destroys serious problem.When little shake occurs, structure and base isolation layer can rely on self shear behavior to resist earthquake action; When central shake occurs, the low strength composite mortar Seismic Isolation of Isolation Layer mixing granulated glass sphere aggregate and vegetable fibre is cut up, its shock insulation function is excited, the granulated glass sphere that the Seismic Isolation of Isolation Layer mortar cut up comprises rolls under earthquake action, rolling resistance dissipation seismic energy is relied in rolling process, reach the object of protection superstructure, to avoid causing larger earthquake to superstructure; Simultaneously in rolling process, the vegetable fibre that Seismic Isolation of Isolation Layer mortar comprises relatively can limit the rolling of granulated glass sphere on the one hand, even if also increase the resistance rolled, thus makes the power consumption effect of the more effective performance Seismic Isolation of Isolation Layer of Seismic Isolation of Isolation Layer energy; On the other hand, the vegetable fibre of Seismic Isolation of Isolation Layer admixture, while restriction granulated glass sphere rolls, can reduce integrally-built vibration amplitude, reduce the horizontal shift of structure, reach good quake evaluation object.
For achieving the above object, technical scheme of the present invention is: the low strength composite mortar mixing granulated glass sphere aggregate and vegetable fibre, it is characterized in that it is mixed together with certain proportion by combined aggregate, cement, lime putty, vegetable fibre and water, its weight ratio is cement: combined aggregate: vegetable fibre: lime putty: water=1:(8 ~ 12): (0.12 ~ 0.80): (0.8 ~ 1.3): (1.2 ~ 1.5); Combined aggregate is granulated glass sphere and natural fine sand, and wherein mass ratio shared by granulated glass sphere is 70% ~ 85%.
The renewable granulated glass sphere that it is Raw material processing that described granulated glass sphere adopts with glass cullet etc., granulated glass sphere diameter is 3.5 ~ 5mm, has starting material to be easy to get, recyclable recycling, the advantage of environmental protection, economy.
Described fine sand adopts natural river sand, and material has widely distributed, the feature conveniently selected.Fine sand maximum particle diameter is by 2.5mm sieve aperture.
Described cement is ordinary Portland cement, and strength grade is 42.5R.
Described lime putty is paste product after unslaked lime (CaO) slaking, and effective constituent is Ca (OH)
2.Slaking lime putty has increases mortar workability and water-retentivity, but does not cause remarkably influenced to mortar strength.Lime putty also can use volcanic ash, industrial slag powder etc. to substitute.
Described vegetable fibre comprises the natural plant fibres that snappiness is good, retardancy is good such as flaxen fiber (hemp cut), bamboo fibers, cotton stalk fiber.In suitable situation, described vegetable fibre should be broken for length 25mm ~ 40mm junior unit, better to play its retardation under described mortar sliding mode.
The above-mentioned preparation method mixing the low strength composite mortar of granulated glass sphere aggregate and vegetable fibre, is characterized in that it comprises the steps:
1) in each raw materials quality ratio cement: combined aggregate: vegetable fibre: lime putty: water=1:(8 ~ 12): (0.12 ~ 0.80): (0.8 ~ 1.3): (1.2 ~ 1.5), in combined aggregate, granulated glass sphere mass percent is 70% ~ 85%, the materials of described mortar of purchasing;
2) one of following method is adopted to prepare mortar: 1. combined aggregate, cement, lime putty, broken uniform vegetable fibre to be added water and stirred, the low strength composite mortar of granulated glass sphere aggregate and vegetable fibre must be mixed; 2. combined aggregate, cement, lime putty, broken uniform vegetable fibre are added water after fully stirring evenly again and stir mix the low strength composite mortar of granulated glass sphere aggregate and vegetable fibre.
The effect that fine sand and granulated glass sphere play in mortar, aggregate is filled; Lime putty also has certain hydraulicity, has cementation, replaces certain cement, saves cement consumption, reduces the delamination degree of mortar simultaneously and improves its water-retentivity.
Compared with existing goods mortar, the present invention has following benefit fruit:
1, with granulated glass sphere for mainly to mix aggregate, achieving the recycling to discarded glass, achieve the repetition sustainable use of resource, is a kind of saving and protection to existing resource.
2, using the present invention as a kind of base isolation layer of building, have isolating affection remarkable, construction is simple, and the advantage that economic cost is little, is particularly useful for promoting in country building.
Experiment shows, use mix granulated glass sphere aggregate and vegetable fibre low strength mortar based on the house of Seismic Isolation of Isolation Layer, under earthquake action, the acceleration response of superstructure reduces 35%-58% than the acceleration response of general house, and the frequency decay of Isolating Building is much slow more than the frequency decay under general house earthquake action, and frequency decay is faster, structural seismic capacity is more weak, and structural impairment is more serious.As can be seen here, remarkable as a kind of isolated component isolating affection using the present invention
3, feed distribution extensively, environmental protection is easy to get, and low cost product, is convenient to marketing.
4, the method technique simple, be easy to construction.
