Description
Technical field
The present invention relates to a kind of material of construction, concrete is a kind of cement-based floor self-leveling mortar and preparation method thereof.
Background technology
At present, along with improving constantly of construction quality, also demand is higher day by day for the quality of building ground floor mortar, and cement mortar surface is industry and the most general engineering position of covil construction.The tradition mortar all is to purchase cement and sand at the scene, and the building site adds water voluntarily and stirs.Use traditional sand finish, the expense of taking a lot of work material, labour intensity is big, and often runs into the quality problems of mortar in construction and application process, and is also unsuitable as the desired combination material that building ground is repaired.Tradition mortar quality is not, and is stable, water-retentivity and mobile poor, and time of coagulation is slow, and intensity is low, has reduced early strength and final strength, occurs honeycomb and scale, hollowing, dusting easily, plays grey phenomenon.In recent years, the ground self-leveling material constantly was seen in report, but existed price high as epoxy resin, can not guarantee as the ordinary portland cement class intensity and time of coagulation.
Summary of the invention
Purpose of the present invention is intended to improve the quality of building ground mortar, and rational Application flyash is for realizing the low water-cement ratio of material, large fluidity; The degree of compactness height prevents segregation; Cohesiveness is good, and thin layer high-performance such as plaster provides a kind of cement-based floor self-leveling mortar and preparation method.
The present invention is the deficiency that solves the problems of the technologies described above, and the technical scheme that is adopted is: cement-based floor self-leveling mortar is made up of the component of following mass parts, 70～90 parts of silicate cements; 10～30 parts of high-alumina cements; 20～40 parts in flyash; 160～180 parts of quartz sands; 0.5～1.5 part of high efficiency water reducing agent; 0.1～0.5 part of sodium lignosulfonate; 0.05～0.15 part of Vltra tears; 0.5～1 part of rubber powder; 0.005～0.015 part of defoamer.
Silicate cement of the present invention is 42.5 grades a ordinary Portland cement;
Described high-alumina cement is 52.5 grades a high-alumina cement, and the adding of cement can be regulated mortar time of coagulation and play certain expansion.
Described flyash is I level flyash, can better improve the flowability of mortar behind the adding flyash.
Described quartz sand is the quartzose sand or the river sand of clean dry, and fineness modulus 0.9-1.7, quartz sand have very strong resistance to acid medium etch ability, increases the acidproof resistance of mortar.
Described high efficiency water reducing agent is a naphthalene water reducer, as: high dense type water reducer, add the water cement ratio that high efficiency water reducing agent greatly reduces mortar, increased flowability, also improved the intensity behind the mortar hardening.
Described sodium lignosulfonate utilizes its cohesiveness, dispersiveness, and chelating to improve the physical and chemical performance of mortar, is saved cost, raises the efficiency, and sodium lignosulfonate also plays the effect of antiscale and inhibition.
Described rubber powder is the high molecular polymer rubber powder of cold water solubles, as: JGB high molecular polymer rubber powder adds rubber powder and has improved the cementability of mortar, soft property and water tolerance.
Described Vltra tears is viscosity 40000s, and the high-moisture-retention of Vltra tears can make the abundant aquation of cement, obviously increase cohesive strength, can suitably improve tensile resistance degree and shearing resistance simultaneously, greatly improves construction effect.
Described defoamer is commercially available common defoamer, utilizes it to eliminate the foamy characteristic, effectively controls sand-cement slurry system inner foam and produces, and has reduced the mortar surface tension, prevents that pitted skin from appearring in mortar.
The preparation method of a kind of cement-based floor self-leveling mortar of the present invention is:
Step 1, get 160～180 parts of the quartz sands of fineness modulus 0.9～1.7, drying, stand-by;
Step 2, get 0.005～0.015 part of 0.5～1.5 part of high efficiency water reducing agent, 0.1～0.5 part of sodium lignosulfonate, 0.05～0.15 part of Vltra tears, 0.5～1 part of rubber powder and defoamer, mix, standby;
Step 3, get 70～90 parts of silicate cements and high-alumina cement is put into the taper dry powder blender for 10～30 parts, start is stirred and was ended in 1～2 minute;
Step 4,20～40 parts of starts of adding flyash continue to stir, and stir 2～3 minutes;
Step 5, the described high efficiency water reducing agent of adding step 2, sodium lignosulfonate, Vltra tears, rubber powder and defoamer, start was stirred 1～2 minute, added the described quartz sand of step 1 at last, stirred to end, and discharging makes finished product.
Beneficial effect is:
The used starting material of the present invention measure in proportion in factory, fully stir with dry powder blender and form steady quality; After the working-yard stirred by certain ratio of water to material, falling on the ground can without vibration, exempt to smear pressure, can form bright and clean smooth ground floor; Use the present technique product, can reduce labour intensity, save construction cost, improve construction quality; Mortar fast solidifying of the present invention is solid wear-resisting; Ground thin layer material-saving, smooth and beautiful appearance, solid wear-resisting, reduce to shrink and do not ftracture, be applied to new ground construction, prevent that effectively the ground coat of plaster from playing defectives such as ash, crack, hollowing and foaming; Also can be advantageously applied to and wearing and tearing, dusting, nappy old ground reparation occur.
