INFLUENCE OF CONSOLIDATION METHOD FOR TEST SPECIMEN ON ACTIVITY INDEX TEST RESULTS OF MICRO POWDER FOR ULTRA-HIGH STRENGTH CONCRETE

Abstract

Influence of consolidation method for test specimen on activity index test results of micro-powder for ultra-high strength concrete based on mortar was investigated. This investigation led to the following conclusions. 1) Density and compressive strength of standard mortar and test mortar using volcanic glass powder were increased using a vibrator. 2) Coefficient of variation of the compressive strength was not changed by consolidation method. 3) As a result of the 1), consolidation method for test specimen influenced activity index test results.
