2, the anti-ability of pressing against brokenly significantly improves, and under 130 ℃ of conditions, after the weight 300mm of 500g highly impacts, under the pressure of 500mm water column, observes after 16 hours, does not have the phenomenon of infiltration the site traffic in the time of can bearing the petrolize roll extrusion to occur.
3, the performance of anti-low-temperature cracking improves greatly, under-20 ℃ of conditions, carries out stretching experiment with the pulling rate of 50mm/min, the result shows that coiled material tensile strength of the present invention is more than 8.2Mpa, and unit elongation is more than 28%, the industry standard that is higher than Japanese like product, fair with the industry standard of Germany.Coiled material of the present invention can be comply with the incompleteness of concrete surface and not split bad.Can absorb the stress that the concrete microfracture produces and do not break, show that it has high resistent fatigue characteristic.
4, to concrete cohesiveness height, reach 0.14Mpa in the time of 60 ℃, reach 0.55Mpa in the time of 15 ℃, guaranteed that the road of laying can not bubble or layering.
5, salt tolerant, alkali resistance are strong, at Ca (OH)
2In soak 15 days no abnormal, soak in 3% salt solution 15 days no abnormal, be suitable for the use under the different soils environment.
6, coiled material of the present invention is not influenced by the freeze thawing round-robin, and the shear at high temperature excellent property, under 60 ℃ of conditions, presses fast 10mm/min, and under the vertical pressure of 0.1Mpa, shear at high temperature pressure is 0.13Mpa.
