This paper reports an investigation into the influence of particle size distribution (PSD) of ground granulated blast furnace slag (GGBS) on the bleeding characteristics of slag cement mortars.
Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied to other granular materials. This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain.
Particle size, also called grain size, means the diameter of individual grains of sediment, or the lithified particles in clastic rocks.The term may also be used for other granular materials.

Particle size is a notion introduced for comparing dimensions of solid particles (flecks), liquid particles (), or gaseous particles ().The notion of particle size applies to colloidal particles, particles in ecology, particles present in granular material (whether airborne or not), and particles that form a granular material (see also grain size
Apr 17, 2017· I had practically used PPC cement in almost all projects. I didn't find any problem. Portland Slag Cement (PSC) Portland Slag Cement (PSC) is manufactured by either inter-grinding in the Portland cement clinker, Gypsum & Granulated Slag or blendin...
This paper presents the results of an investigation into the influence of fineness and particle size distribution of granulated blast-furnace slag (GBFS) on its hydraulic reactivity in cement systems.
PARTICLE SIZE PARTICLE SHAPE Introduction The aim of this guide is to provide you with a basic grounding in the main particle characterization techniques currently in use within industry and academia. It assumes no prior knowledge of particle characterization theory or instrumentation and should be ideal for those new to particle characterization,
May 20, 2014· The characteristic of GGBS was examined using particle size analyzer, X-ray diffraction (XRD) and chemical analysis tests. Table 1 shows the physical and chemical properties, whereas Figs. 1 and 2 show the particle size distribution and XRD test result of the GGBS respectively. The average particle size of GGBS was 9.2 μm compared to 14.6 μm for PC (type II).
GGBS is obtained by quenching molten iron blast furnace slag (a by-product of iron and steel making) in water or steam. It is then further grounded into the desired fineness in terms of the required particle size distribution. The main components of blast furnace slag are CaO (30-50%), SiO2 (28-38%), Al2O3 (8-24%), and MgO (1-18%).
particle size measuring under 20 µm. Only 10% to 30% of the particles by mass are larger than 45 µm. The surface 58 Design and Control of Concrete Mixtures ... Chapter 3 Fly Ash, Slag, Silica Fume, and Natural Pozzolans 3 3 ...
Jun 20, 2014· Thanks for the A2A Prasad Rajan The main advantages of using mineral admixtures are 1) particle size, 2) pozzolanic effect 1) Particle size In case of fly ash, slag or silica fume (further nano silica, nano alumina), the particle size (bulk of ...
Concrete, usually Portland ... (GGBFS or GGBS): A by-product of steel production is used to partially replace Portland cement (by up to 80% by mass). It has latent hydraulic properties. ... but has a particle size 100 times smaller. This results in a higher surface-to-volume ratio and a much faster pozzolanic reaction. Silica fume is used to ...
GGBS cement also produces a smoother, more defect free surface, due to the fineness of the GGBS particles. Dirt does not adhere to GGBS concrete as easily as concrete made with Portland cement, reducing maintenance costs. GGBS cement prevents the occurrence of efflorescence, the staining of concrete surfaces by calcium carbonate deposits.
Particle size's wiki: Particle size is a notion introduced for comparing dimensions of solid particles ( flecks ), liquid particles ( droplets ), or gaseous particles ( bubbles ). The notion of particle size applies to colloidal particles, particles in ecology, particles present in granular material (whether airborne or not), and particles that form a granular material (see also grain size).
Particle a is twice the size of particle b. Above is a plot of the radial intensity of diffracted light through a cross-section (shown as a red arrow). As shown in the equations, the size of the Airy disk is directly proportional to the wavelength (λ), but inversely proportional to the size of the particle (d).
The particle size distribution (PSD) of GGBS can also affect the physical and mechanical properties of concrete, but this cannot be sufficiently addressed by the standard testing methods. This paper proposes a quantitative assessment method which can quickly determine the particle shape and PSD of CEM I cement and GGBS samples based on electron ...
To study the effect of particle size of GGBS for con crete, the uniform size particles are taken as 250µm, 125µm, 90µm, 45µm and 20µm. The GGBS was used here as replacement to cement.

The UK nuclear industry has historically used a unique specification of cement powder that differs from construction industry requirements. However, the slags that complied with this specification have become unavailable. The material now used to meet the requirements of the specification is a blend of standard construction industry ground granulated blast-furnace slag (GGBS), which has high ...
The grinding process takes account of mean particle size, grading (particle size distribution), fineness and the particle shape in order to ensure that when used in concrete performance is maximised. Typically GGBS possesses a specific surface area of 450-550 m2/kg.
