In order to predict the application effects of inorganic polymer-based fast-hardening concrete (IPFC) in pavement emergency repair, slag, fly ash and silica fume were used as solid cementitious materials, sodium hydroxide silicate alkali-activators prepare IPFC specimens. The change rules basic mechanical properties specimens with different contents early stage studied by experiments. results s...

As an environmentally friendly pavement material, porous concrete in seasonal frozen region is often subjected to repeated loads and freeze-thaw cycles. Therefore, the fatigue property of under extremely important. However, few researches have been reported on topic. Based this background, paper investigates flexural ground tire rubber/silica fume composite modified (GTR/SF-PC) with experimenta...

The degree of dispersion of short microfibers in cement, as assessed by electrical resistivity measurement for the case of electrically conductive fibers at a volume fraction below the percolation threshold, is improved by the use of admixtures ~namely, silica fume, acrylic particle dispersion, methylcellulose solution, and silane! and fiber surface treatment ~such as ozone treatment!. Acrylic ...

This work presents the effect of room temperature vulcanized (RTV) silicone rubber coating on cap and pin type porcelain insulator under ac (50Hz) flashover voltage (KV). Describes experimental results obtained for improvement of porcelain insulator removed from 33kV overhead transmission line at Aswan, Egypt after 28 years of service. Also, this study briefly surveys the environmental contamin...

Abstract In this exploratory research, PET fibre and silica fume were practised for the intensification of commonplace concrete. was at dissimilar proportions 0%, 0.25%, 0.50%, 0.75%, 1.0%, 1.25% & 1.50%, while 2.5%, 5.0%, 7.5%, 10.0%, 12.5% 15.0%. practising research work in efficient manner purest form both kinds constituents purchased from India-Mart physical chemical composition details...

Setiap bangunan terdiri atas bagian-bagian yang memiliki fungsi tertentu, tidak terkecuali juga balok beton. Elemen satu ini sangat berguna untuk menyangga lantai terletak di atasnya. Tidak hanya itu, ternyata peran sebagai penyalur momen menuju ke bagian kolom pada sedang dibuat. Perkuatan struktur beton menggunakan mutu tinggi (High Strength Concrete) dengan komposisi campuran yaitu semen, si...
