Application Study of Wollastonite in Epoxy Resin Road Repair Material
In order to reduce the amount of epoxy resin cementitious materials in epoxy resin-based repair materials,thus reducing the cost of raw materials materials,the effect of wollastonite as a dopant in the application of epoxy resin-based repair materials was studied.The results show that when wollastonite doping is 100%,the flow degree of the repair material is 130 mm,the compressive strength and flexural strength are better than the comparative specimens,and the compressive strength of 1 d and 28 d is increased by 56.4%and 5.5%compared with that of the comparative specimens,respectively.Wollastonite-epoxy repair mortar 28 d shrinkage decreases by 26.18%,under the frost and salt freezing resistance conditions,strength loss is reduced by 17.31%and 13.04%,respectively.Wollastonite-epoxy resin-based road repair material meets the performance requirements of JC/T 2381-2016"Repair Mortar",which expands the application of wollastonite.
