Description
Technical field
The present invention relates to a kind of building mortar, especially relate to a kind of indoor floor leveling mortar and constructional method thereof.
Background technology
As the floor leveling mortar that lightweight floor decorative material bottom layer alignments such as existing timber floor are handled, its component and weight proportion are generally cement 40-50, quartz sand 20-30, coarse sand 10-20, and the proportion of this mortar is 1700-1800Kg/m
3Than great, the capacity value that not only adds the Paris polyphylla body, and consumptive material is many, the carriage vertically burden is heavy, also causes grey pulp grinder to block up pump, plugging, stifled rifle, hinders mechanized construction to carry out smoothly, operating efficiency is low, and self-leveling can be poor, and horizontality is poor, is difficult to reach the effect of disposable rapid shaping (reaching required thickness).
Summary of the invention
But the invention provides a kind of mechanical execution, self-leveling can be good, and horizontality is good, reaches the light mortar used as the floor leveling of lightweight earth material bottom surfaces such as timber floor of being suitable for of disposable rapid shaping easily, and simultaneously, the present invention also provides its constructional method.
For solving the problems of the technologies described above, the invention provides a kind of indoor floor leveling mortar, it is characterized in that, mix by the component of following weight proportion:
Ordinary Portland cement 30-35
White lime 4-5
Light-weight aggregate 5-8
Heavy aggregate 55-60
Composite assistant 1.0;
Described light-weight aggregate is that fineness is lower than the inorganic vitreous hollow microporous material of 100 purposes; Described heavy aggregate is a common river sand;
Described composite assistant is mixed by polymer dispersion powder 0.1 weight part, ether of cellulose 0.3 weight part, water reducer 0.5 weight part, setting accelerator 0.1 weight part.
Described composite assistant is the E type composite assistant of the synthetic trading company in Guangzhou.
Described inorganic vitreous hollow microporous material fineness is the 60-100 order.
The fineness of described common river sand is the 25-50 order.
Described ordinary Portland cement is the black cement that is greater than or equal to the R325 model.
The fineness of described white lime is more than 300 orders.
Described indoor floor leveling mortar is mixed by the component of following optimum weight proportioning:
Ordinary Portland cement 30
White lime 4
Light-weight aggregate 6
Heavy aggregate 59
Composite assistant 1.
The present invention also provides a kind of constructional method of described indoor floor leveling mortar: with the 30-50% thin up of described indoor floor leveling mortar by its weight, mechanical or manual stirring is until mixing, reach the viscosity that is fit to mechanically spraying or manual construction, can mechanically spraying or manual construction.
The present invention adds inorganic vitreous hollow microporous material, has increased the space of mortar, reduces the whole proportion of mortar greatly, and mortar is done apparent density (Kg/m
3) be reduced to 1000-1200 from the 1700-1800 of prior art mortar, effectively alleviate building body capacity value, also solved because of mortar from the great stifled pump that produces, plugging, stifled rifle problem, blunge gets final product pumping, helps mechanized construction; Adopt inorganic vitreous hollow microporous material also to increase porosity, reduced the material usage of unit surface, the vertical-lift weight of mortar also reduces thereupon greatly, thereby reaches effectively energy-conservation, has also reduced the cost cost of unit surface.After the mortar lighting, proportion reduces to make thermal conductivity also to decrease, and the thermal conductivity of floor leveling mortar of the present invention (W/ (25 ℃ of mK)) between 0.22-0.48, improves heat insulation decrease of noise functions.
In the composite assistant that the present invention adopts, 1) water reducer has the intensive dissemination to gelling material such as cement in water, can improve the flowability of mortar greatly; 2) ether of cellulose is soluble in water with colloid and polymer morphology, strengthens water-retentivity, helps flowability; 3) redispersable latex powder also can make mobile the enhancing; 4) the setting accelerator composition can shorten the time of coagulation of ground mortar and improve early strength.In addition, add inorganic vitreous hollow microporous material and make the mortar lighting, make relatively moving easily between the different particle of various particle diameters, promptly mobile the raising.Like this, various composition actings in conjunction, flowability strengthens and the mortar rapid solidification greatly, makes that floor leveling can rapid construction, disposablely reaches required levelling thickness, and levelness and planeness height.
In the mortar of the present invention, various components improve the workability of this mortar effectively: 1) ether of cellulose, as the stablizer in the mortar, keep good denseness stability and improve adhesive property, reduce the performance of losing moisture, delayed moisture by the absorption of porous material, help hydrated cementitious and prolong the open hour, strengthen water-retentivity, help flowing, its surface can also be suitable pockets of entrapped air tend, these air filled cavitys of carrying secretly can play the effect of " lubricant "; 2) white lime, can adsorb the thicker moisture film of one deck at cement surface,---comprise mortar-basic unit interface region, mortar-interface region and mortar inside gather materials---all produces latex film at different positions with the effective bound energy of redispersable latex powder, between various particles, play " lubrication ", white lime and redispersable latex powder acting in conjunction, make that intergranular sliding-frictional resistance becomes littler in the mortar, intergranular having relatively moved easily; 3) water reducer has improved the degree of mobilization of mortar.Like this, mortar stream is easier to flow, and it is more sliding that quality becomes, and it is more smooth and easy that the mortar plaster is got up, and workability improves, and also more helps the pumping and the sprayability of mechanized construction, has improved operating efficiency and construction quality greatly.
At present, in mortar for building field, commerical ready-mixed concrete is in the process of high speed steady progression, and commodity mortar also is the developing new trend of urban architecture adnornment industry, common dry-mix has belonged to the novel product category, and the lighting field of mortar also relates to regard to rarer people.The applicant adopts special light-weight aggregate to reduce the proportion of lightweight floor leveling with mortar according to the thinking of lighting, makes it lightweight, helps mechanized construction, and alleviates building body capacity value, raising building safety anti-seismic performance; Simultaneously, also adopt special composite assistant to make it have the self-leveling energy in the present invention, disposable apace reach levelling thickness, planeness good, easily receive light, be very suitable for using as the floor leveling of lightweight earth material bottom surfaces such as timber floor, construction fast, features simple and practical process, unit area building cost is cheap, and promotional value is arranged very much.
