Study Pembuatan Durable Cement dengan Penambahan Pozzolan Silica Fume

A study of Metakaolin and Silica Fume used in various Cement Concrete Designs

In the present study, effect of pozzolanic material (Metakaolin and Silica fume) is studied through compressive and Flexural strength in cement concrete. Metakaolin and silica fume area used as cement replacement materials at 5%, 10% and 15% by mass keeping water–cement ratio as 0.42 Compressive and Flexural strength were observed after 7 and 28 days of curing. Silica fume is a by products resu...

Taftan Pozzolan-Based Geopolymer Cement

  Abstract: In recent years, many research works have been done to investigate the possibility of utilizing a broad range of materials as raw materials in the production of geopolymer cements. The use of artificial pozzolans or aluminosilicate-type industrial waste materials such as granulated blast-furnace slag and fly ash has been reported in many research works. Natural pozzolans are also al...

Influence of silica fume on the microstructure of cement pastes: New insights from 1H NMR relaxometry

a r t i c l e i n f o Keywords: 1 H NMR (B) Silica fume (D) C–S–H composition (B) Density (B) 1 H NMR has been used to characterise white Portland cement paste incorporating 10 wt.% of silica fume. Samples were measured sealed throughout the hydration without sample drying. Paste compositions and C–S–H characteristics are calculated based on 1 H NMR signal intensities and relaxation analysis. T...

Low Temperature Synthesis of Belite Cement Based on Silica Fume and Lime

This paper describes the low temperature synthesis of belite (β-C2S) from silica fume. Mixtures of lime, BaCl2, and silica fume with the ratio of (Ca + Ba)/Si = 2 were hydrothermally treated in stainless steel capsule at 110-150°C for 2-5 hours, calcined at 600-700°C for 3 hours, and analyzed by FTIR, XRD, TGA/DTA, and SEM techniques. Dicalcium silicate hydrate (hillebrandite) was prepared by h...
