A DISCUSSION OF THE PAPER "VERY-HIGH-PERFORMANCE CONCRETE WITH ULTRAFINE POWDERS" BY GUANGCHENG LONG, XINYOU WANG AND YOUJUN XIE

In this brief article, the author comments on research undertaken by Long et al (2002) on the compactness and fluidity of binary and ternary compound paste systems containing ultrafine powders such as pulverized fly ash (PFA), pulverized granulated blast furnace slag (PS) and silica fume (SF). In the study, through optimization of the proportions of compositions and applying heat treatment to specimens, a very-high-performance concrete (VHPC) including large quantities of ultrafine powders was made that offers compressive strength up to 200 MPa. This discussion takes the authors to task on eight points regarding the Long et al research: the terminology of very-high-performance-concrete; the chemical oxide composition of fly ash used; the relative density due to lower mean diameter; reductions in water/binder ratio; contradictory results in a table depicting the introduction of fly ash into paste mixture; the lack of information on sand content; the claims regarding the compressive strength of VHPC; and a small syntax error.
