Wear-resistant material used ground hardener material, the material from the non-metallic mineral aggregate, metallic minerals, aggregate and special additives. Wear resistant with high surface hardness, density, abrasion resistance, not health dust, easy to peel, economic, and apply a wide range of advantages. Overall wear resistant abandon the traditional separation of concrete base and surface construction practices, eliminating the combined result of poor primary and surface cracks and hollowing a result of quality problems, simplify procedures and shorten the construction period, save cost of labor, in factories, warehouses, runways, terminals and other projects to get more and more widely used.
1. Wear-resistant materials
Hardener material points two components of aggregate and cement. Aggregate, sand-like, with an average diameter of 1.5mm, about 60% of the total; cement to the treated high-grade cement, except with cement qualities, there are red, yellow, green, gray and other colors available choice.
Hardener aggregate composed of natural minerals. Department of aggregate non-metal is not rusty, Mohs hardness 8 degrees. In addition to natural mineral aggregate, the other cement, pigment and so the weight does not exceed the total weight of 25%.
Amount of wear-resistant material according to material specifications and design requirements
2. Construction equipment
In addition to use with the trace of conventional concrete floor with wipe office equipment, and the other to prepare the following equipment.
(1) bleeding tools: rubber tubing or vacuum suction device.
(2) smooth out the paste tool: the middle sand 150 irrigation pipe, length greater than the width of 500mm above ground mode, set both ends of the rotating ring-pull.
(3) Fuman ray machine: Canada's production for the four-leaf steel chassis, steel by adjusting the angle (for angle than the soft surface layer of small, hard surface layer for the large angle) calendering the ground surface.
(4) flat shoes: after the initial setting of concrete used; waterproof shoes or waterproof paper bag; surface layer of leaves to use calendar.
3. Construction Organization
To 500m2 / d prevail, in addition to conventional poured concrete down the ground with the staff, construction personnel needed with the following: 3 concrete leveling, abrasion-resistant material transport two people, wear-resistant material spreading 3, Fuman construction of 3-ray machine people Trowel Shuhei 3. According to the above criteria, uninterrupted construction, 6 to 7 units trowel and with the appropriate personnel to complete 2000m2 / d.
4. Construction preparation
(1) under the floor with a Roller compacted sand and gravel bedding.
(2) level set by the design template (steel template or channel), detection of the template at any time with the water level elevation, Office of the deviation of block with a wedge adjustment.
(3) According to the specifications, by vertical and horizontal axis of sub-storage compartments sewn.
(4) the maximum size of gravel used in concrete 30mm, water-cement ratio and the slump should be as small as possible.
(5) concrete grade not lower than 25, live in the 75-100 mm slump.
5. Operation points
Smooth wipes 5.1 Layout
Ink line basis in accordance with the building structure (such as wall +50 cm line), with a floor level in the region to set concrete pouring pouring thick book, set the level of elevation mark, and carefully review, control the largest bump deviation within 3-5mm.
5.2 Concrete pouring
(1) pouring concrete in the foundation before the sprinkler to wet conditions. To reduce bleeding, should control the water-cement ratio and slump, commercial concrete with the use of artificial discharge chute, not by pumping.
(2) pouring concrete to a level as possible, local office does not meet the elevation and the use of concrete materials padded vibration, do not use mortar repair. Plate vibrators using vibrators, with a special steel roller repeatedly rolling, columns, corners and other parts of wood pulp wipe shot. Concrete Calibrating bubble to the surface after the grout at least 3 mm thick.
(3) completion of concrete placement, using rubber tubing, or vacuum equipment to inter bleeding, repeated after two or more wear-resistant material construction. Wear-resistant materials before construction, the medium-term operational phase construction workers should wear flat shoes to enter the late stages of operation should wear waterproof shoes into the paper.
5.3 for the first time spreading resistant materials and disappearing, Fuman light
(1) the timing of spreading resistant materials with weather, temperature, concrete mix and other factors change. Spreading premature wear-resistant materials will sink into the concrete effects of the loss; spreading late concrete has solidified, the loss of bond strength, wear-resistant materials so that their combination can cause peeling. Determine the time of wear resistant materials is spreading foot on it, about sinking 5mm, they can begin construction of the first spreader.
(2) walls, pillars, doors and templates and other sideline Department moisture away quickly, spreading should give priority to construction, to prevent effects due to water loss and lower.
(3) The first volume is the total amount of spreading of 2 / 3 Mixture should be uniform down, can not throw Erzhi force separation, after spreading of wood trowel to smooth out. Wear-resistant material, after absorbing some water, and then machine milled dispersion Fuman knife and combine with the primary concrete slurry.
5.4 second spreader resisting material and disappearing, Fuman light
(1) when the second spreader, first scrape by foot or flat bar to measure the level of degrees, and adjust the first spreader uneven Department, and the second should be the first time spreading the vertical direction.
(2) The second volume for the entire amount of spreading 1 / 3, spreading immediately after disappearing, Fuman light, and repeat the Fuman-ray machine operating at least twice. Fuman-ray machine operation shall be vertical and horizontal to the staggered, uniform and orderly to prevent the material gathered. Corner Office, wood trowel handle.
(3) surface layer of hardened material to massage a little settlement, the Fuman ray machine, as the hardening speed and angle of the situation should be adjusted Fuman criss-cross ray machines should be more than 3 times.
(4) wear-resistant floor flatness requirements for the maximum deviation of 2m square, 3-5mm, with the elevation of high point and low point of maximum deviation is less than 20mm. Avoid cracking, peeling, or from the sand phenomenon.
5.5 Surface Modification and Maintenance
(1) Fu-man-ray machine operating behind the layer of still more messy wipe patterns, to eliminate the wiping pattern across the last layer using thin steel trowel orderly, with the artificial calendar to complete the modification process.
(2) wear resistant construction maintenance dose 5-6 hours after the spraying of conservation, the dosage of 0.2 l / m2. Or plastic film cover to prevent surface cracking caused.
(3) wear resistant surface construction can be completed 24 hours after form removal, but should pay attention to not damage flooring edge.
(4) 5-7d after the completion of cutting to do a joint, to prevent irregular cracking, cutting sutural appropriate for the 6-8m (generally based on columns from the workshop to determine). Cutting should be unified elastic line, to ensure that the joints neat straight cut, cutting depth should be at least floor thickness of 1 / 5, sealing materials, molding or cutting by pre-elastic resin material, it is recommended to use sealants.
