The paper considers how cullet of different particle-size distribution affects the concrete strength. Experiments have proven that large-particle cullet (1.25 cm or larger) could be used as an aggregate; the concrete strength will be on par with those of ordinary natural/crushed sand concrete. The paper proves the feasibility of injecting highly dispersed silica fume in combination with effective polycarboxylate-based superplasticizers in cullet-based concrete mixtures. Highly dispersed silica fume will positively affect the strength characteristics of concrete, as silica fume in cement rock reacts with Са (ОН)2, which is released upon the hydration of the clinker minerals С3S and С2S; the reaction produces very strong compounds. Concretes containing up to 30% silica fume in combination with a superplasticizer will feature very high early strength. Use of strong aggregates with a 30% cullet content can produce strong concretes; after steamed, a concrete containing silica fume and polycarboxylate-based superplasticizer will reach 90% of the graded strength. Cement-rock microstructure studies show that the polymer component of the STACHEMENT 2280 superplasticizer will gradually transcend from the glass grains to the cement rock. The interface between the polymer-coated glass grains and the cement rock is blurred and barely present. This strengthens the glass-rock adhesion and improves the concrete strength. This is why cullet is recommended for use in the production of curb stones.

Cullet Content

Lateritic soil treated with up to 20% glass cullet content was subjected to grain-size distribution, consistency tests, specific gravity tests, compaction using standard proctor, California Bearing Ratio (CBR), unconfined compression test, direct shear test and permeability tests. The study showed increase in grain sizes resulting in coarser soil, changes in moisture-density relationship, resulting in lower Optimum Moisture Content (OMC) and higher Maximum Dry Density (MDD), an increase in CBR, an increase in unconfined compressive strength (UCS); changes in cohesion-frictional angle relationship resulting in lower cohesion (c) and higher angle of internal friction (Φ) and an increase in co-efficient of permeability, k, with increased glass cullet treatment. These results show an improvement in geotechnical properties, making glass cullet-lateritic soil blend; a potentially good highway material and suggesting the suitability of the blend for embankments, structural and non-structural fill and retaining wall backfill.

This paper reports the application of Taguchi optimization technique in determining process condition for synthetic lightweight aggregates by incorporating waste liquid crystal displays (LCD) glass with reservoir sediments. In the study the waste LCD glass cullet was used as an additive. It was incorporated with reservoir sediments to produce lightweight aggregates. Taguchi method with an L16(45) orthogonal array and five controllable 4-level factors (i.e., cullet content, preheat temperature, preheat time, sintering temperature, and sintering time) was adopted. Then, in order to optimize the selected parameters, the analysis of variance method was used to explore the effects of the experimental factors on the performances (particle density and water absorption) of the produced lightweight aggregates. The results showed that it is possible to produce high performance lightweight aggregates by incorporating waste LCD glass cullet with reservoir sediments.

Cullet Content

A series of (x) paper ash- (80-x) cullet – 20 Kaolin clay where 10 ≤x≤30 weight % has successfully been prepared using solid state reaction method. The ceramic density and hardness has been determined using Archimedes and Vickers hardness method respectively. The dielectric constant and dielectric loss has been determined using impedance analyzer. The obtained density is descending from 2.18 gcm-3 to 1.90 gcm-3 and hardness is increased up to 871.8 Mpa. The decrement of density and hardness as the cullet content increases is due to the non uniform vitreous areas formed in between ceramic particle. The variation of the dielectric constant and dielectric loss tangent are found to decrease with increasing of frequency which suggest the dipolar polarizability properties. It is found that the maximum value of dielectric constant is 3000 and minimum dielectric loss tangent is 0.166.

A series of ceramic based on (x) titanium nitride- (60-x) cullet-40 kaolin clay, (where 0≤x≤6 wt%) has successfully been made by dry pressing technique followed by sintering at 1000 o C. The actual composition of ceramic is analyzed using Energy Dispersive of X-Ray (EDAX) while the phase existence is determined using X-Ray Diffraction (XRD) technique. Their microstructural morphology is observed under Field Emission Scanning Electron Microscope (FESEM) and the physical properties are determine in term of their density and hardness. It is found that the ceramic contain mostly of Silica and the phase occurrence is dominated by two major phases namely, quartz and tridymite. The structural morphology is observed to be in the form of dendrite structure, with the size become larger as cullet content is decreased. The density is found in the range of 1.941-3.019gcm -3 while the hardness is in the range of 1.174-1.773GPa depending on composition level.
