Six characteristics - epoxy grouting material strength Epoxy grouting material and prestressed pipe pressure slurry

Epoxy grouting epoxy grouting material strength epoxy grouting material strength determine epoxy grouting material construction aspect has reliable quality, reduce cost, shorten the construction period and the advantages of easy to use, is widely applied to the construction and road maintenance, and other fields, after I found that research specialist at the company's strength of epoxy grouting material has the following six major characteristics: 1, with the origin and different varieties of cement strength of gravel grouting material the applicability of the formula there is a difference, the measured values are often lower than design value. 3, before and after adding the expansion of seam an agent grout strength of 28 d and 90 d intensity compared to at least 12%; When inflation is suitable for the growth is higher than when not in mixed. When the inflation rate is too large. This growth will be smaller. According to the 3. 5 years, 5. 5 years of test body for a long time, strength of grouting material can be increased to more than 160% of 28 d. This growth for 90 d intensity of utilization to provide the basis. 4, cement mixing expansion after the seam an agent, when the inflation rate increase, try its expansive cement mortar strength and the match is not closely related to the strength of grouting material, this is because the two try body caused by the difference of size and shape, the same strength of cubic try body than long strip body to the expansion of the constraint function is strong. & Nb sp; high-strength non-shrink grout material manufacturer 5, similar to ordinary grouting material, water cement ratio rule applies to the mixing efficiency of uea shrinkage compensation grouting material strength design calculation, including moderate levels of low slump grouting material, also includes the c35 ~ c50 big slump pumping grouting material. 6, compensation shrinkage grouting material is lower than normal 7 d strength of grouting material around 10%, about two out 70% of the epoxy resin grouting material intensity of 8 d, this is the expansion rate in the embodiment of the rapid development of 3 ~ 7 d, can in shaanxi grouting material manufacturers have delayed hardening the beneficial effects of shrinkage, prevent cracks. Small make up suggest city of epoxy grouting material quality, price, service not guaranteed, advised to choose a straight for grouting material manufacturers, select normal manufacturer production product, beware of counterfeit.
