Experimental Research On Fibre Reinforced Cement Mortar Strength By Pull-out Post-insert Method

Domestic and foreign experts have made great achievements to detect the compressive strength of concrete.This thesis mainly research Pull-out Post-insert Method for experiment the strength of Fiber Reinforced Cement Mortar. Through the analysis of test data, fitting strength curve have been given for the Fiber Reinforced Cement Mortar, making up the method of detecting the strength of Fiber Reinforced Cement Mortar thin layer on actual project, simultaneously provides experimental basis and theoretical analysis for Pull-out Post-insert Method detecting Fiber Reinforced Cement Mortar strength test technical specification.Two fiber cement mortar are studied including Polyvinyl Alcohol-Engineered cement mortar and Steel fiber cement mortar. In the first determined the fitted curve form based on experiment data calculation. Using least square method calculate the regression equation parameter. For different strength grade of Fiber Reinforced Cement Mortar using hydraulic press and Pull-out Post-insert Method calculate the strength separately. The significant differences for regression model are analyzed by t test and F test.The differences about the regression equation between Polyvinyl Alcohol-Engineered cement mortar and concrete are also analyzed.At last, feasibility analysis is discussed about Pull-out Post-insert Method for detecting the strength of Fiber Reinforced Cement Mortar.The test process and failure mechanism are analyzed.For the regression equation parameter calculates the confidential interval.For the two regression equation correction coefficient are analyzed.Engineering application are discussed also.Influential factors about Pull-out Post-insert Method for detecting the strength of Fiber Reinforced Cement Mortar were analyzed, and the matters needing attention during the process are explained lastly.
