...Aktham H. Alani; Megat Azmi Megat Johari; Ahmed Tareq Noaman; N. Muhamad Bunnori; T. A. Majid The influence of varying contents of supplementary cementitious material, namely silica fume (SF), on the transport properties of ultra-high performance concrete containing polyethylene therephthalate (PET...

...Ashley S. Carey; Isaac L. Howard; Jay Shannon The use of silica fume in high-strength and ultra-high performance concretes has been studied from many perspectives including optimum replacement rate, implications on late-age strengths, and rheological properties. However, the effects of silica fume...

... aggregate-2 concrete, respectively. The addition of silica fume improved the average microhardness, and the same was reflected in the mechanical properties of both the recycled coarse aggregate concretes. It is recommended to use ball mill processed recycled coarse aggregates as a complete replacement...

...Ghasem Pachideh; Majid Gholhaki; Amin Moshtagh The technical and economic advantages of porous concrete pavement have drawn the attention of many researchers. Accordingly, in this study, the effects of cement replacement (10 and 20 %) by pozzolanic materials such as silica fume, zeolite, fly ash...

... and silica fume (SF) with water-to-binder ratios ranging from 13 to 20 % and SF replacement rates ranging from 7.5 to 17.5 %. First, we confirm that the autogenous shrinkage of a concrete specimen can be estimated from that of cement paste by using the theory of composite materials. Second, the SF reaction...

... measurements begin 5 1/2 ± 1/2 h after casting concrete, was used to evaluate the effects of IC obtained through the use of intermediate-sized prewetted LWA, partial replacements of cement with the supplementary cementitious materials slag cement and silica fume (SCMs); incorporation of calcium oxide–based...

...A. Shahriar; M. L. Nehdi This study explores the effects of supplementary cementitious materials (SCMs) on the rheological properties of oil well cement slurries. Four different mineral admixtures including metakaolin (MK), silica fume (SF), rice husk ash (RHA), and class F fly ash (FA) were used...
