(1) to prevent shrinkage cracks Emery wear material is mainly to control two aspects: First, before spreading Emery wear floor materials control the dryness of good concrete surface, such as concrete surface water, then spreading to be clean, otherwise water sites prone to shrinkage cracks; the second is timely cutting expansion joints in concrete pouring two days, wear-resistant floor that 1-2 days after completion of the cutting, and then later to no effect. Method (2) control of its wear-resistant floor cracks steps are: first Reveals layout Emery wear material is in place along the axis and across the midline of the building out of a separate set 200m seam, and then in the structural parts of the distance column 200m in a position to set the four corners of the quadrilateral Reveals closed. Then cutting construction began on the ground floor wear-resistant elastic line must be carried out in accordance with the previous steps Reveals layout, and after playing the wire cutters to cut along the elastic line with the road, the general kerf depth is 50mm. Finally, we generally use the high-pressure pump to wear and cut slits floor after purging, to cut the dust inside seam clean, then use a flexible sealant to fill the slits in the process of formation, there are several points It should be noted. First, you want to cut expansion joints width control in 3 ~ 5mm, depth of concrete thickness of the base control in its 1/2 ~ 1/3 Emery wear characteristics of the material, the width of a column spacing prevail in 6 ~ 8m. Concrete is alkaline, easily reacts with the acid, Emery wear material for acid adaptation is resistant to weak acid, weak base, so we finished floor after Emery wear resistant floor should pay attention to conservation because the color and characteristics of different materials Emery Emery wear wearable material requirements into cement color, gray and color, if it is cement color, gray Emery wear floor, you want to completely dry after resistant floor coating curing agent, if it is the color of carborundum wearable Floor, to finish at 5-6 hours after floor varnish coating agents, curing agents, whether or varnish coating agents, is to keep the ground hardness and color, lock live moisture, dust, to prevent cracking of concrete after the dry, everything is in order to extend the life of the ground, so we must be on the wear-resistant floor conservation in the finished wearable.
