Gel/Space Ratio Evolution in Ternary Composite System Consisting of Portland Cement, Silica Fume, and Fly Ash
In cement-based pastes, the relationship between the complex phase assemblage and mechanical properties is usually described by the "gel/space ratio" descriptor. The gel/space ratio is defined as the volume ratio of the gel to the available space in the composite system, and it has been widely studied in the cement unary system. This work determines the gel/space ratio in the cement-silica fume...
متن کاملEffect of Hydrochloric Acid (HCl) on Blended Cement (Fly Ash based) and Silica Fume Blended Cement and their Concretes
This paper presents the effect of Hydrochloric acid (HCl) on Blended Cement (Fly ash based(BC)) and Silica Fume Blended Cement(SFBC) and their concretes. The BC and SFBC and their concretes BCC and SFBCC produced with HCl dosage of 100, 150, 300, 500 and 900 mg/l added in deionised water. In addition to this control specimens were prepared with deionised water (without HCl) for comparison. The ...
متن کاملMechanical Properties of Epoxy Resin – Fly Ash Composite
There has been significant increase in use of glass fibre reinforced composites as structural materials in naval mine countermeasure surface ships. Sea mines when detonated emit underwater shock waves, which could impart severe loading to naval ship structure; there are attempts to model the response of a ship structure to this loading. For the model to be accurate & useful material property da...
متن کاملInfluence 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...
متن کاملPhysico-Mechanical Properties of Organo-Modified Bentonite Reinforced Cement Mortars
It is demonstrated that the addition of organo-modified Na-bentonite (OMB) particles to Portland cement mortar can promote its physical and mechanical properties. A series of experimental works on some important physico-mechanical properties of Portland cement mortars mixed with various dosages of hydrophobic OMB were performed. The obtained results confirm that the OMB provides a dense packing...
