Definitions

  • a more constructive use for the waste glass is as a pozzolan.
  • a pozzolan is a cementitious material added to a cement composition to prevent deterioration and increase the long-term strength of concrete and mortar products made from the cement composition.
  • pozzolans are typically less expensive than conventional cements, such as Portland cement, when a portion of the conventional cement is replaced with a pozzolan, the overall cost of the cement composition is reduced.
  • waste glass has been little used as a pozzolan in the construction industry because products based on cementitious compositions that contain waste glass as a pozzolan are typically inferior to products formed from cementitious compositions containing only conventional cements, such as Portland cement.
  • cement formulations that include waste glass powder as a pozzolan produce low early strength properties because of the low pozzolanic reactivity of waste glass powder, and consequently such cement formulations can be used only in construction applications where low early strength properties are not detrimental, such as in stabilizing mine backfills.
  • a cement that contains a glass powder pozzolan and has early strength properties that are comparable to conventional cement compositions would have greater applicability in the construction industry and increase the use of waste glass as a pozzolan, while at the same time being more cost effective than conventional cement formulations.
  • the present invention relates to a cementitious composition that comprises cement, glass powder and calcined kaolin.
  • the present invention also includes a cementitious binder composition comprising a mixture of water and the cementitious composition.

  • average strength properties is meant the strength properties and performance that a material exhibits seven days after completion of molding.
  • the ingredients of the cementitious composition prepared according to the present invention will now be discussed in greater detail. Subsequently, products that can be made from the cementitious composition such as a cementitious binder and solidifiable cementitious compositions such as concrete and mortar materials, will be discussed.

  • Glass powder suitable for use in the present invention is formed from glass material including soda-lime glass, borosilicate glass, and lead glass.
  • Soda-lime glass which is a mixture of silica, Na 2 O, and CaO is the most common form of glass used today and the most common form of post-consumer waste glass.
  • Borosilicate glass which is a mixture of silica and B 2 O 3 , is less common but still widely used in materials because of its resistance to chemical and temperature degradation.
  • the most common form of borosilicate glass is PYREX glass.
  • Lead glass a mixture of silica, Na 2 O, and PbO, may also be used, although it is less common than the previous two types in post-consumer waste glass.
  • These glass materials may include optional modifiers and additives such as metal oxides and gallium or tin, which contribute to glass vitrification.
  • the glass materials may also include various chemical impurities such as ceramic and metal wastes.
  • Metal wastes include quantities of iron and lead, which have not been added to the glass material as chemical modifiers.

Notably, it is preferred that the glass material contains less than 10 wt% of K 2 O, and less than 2 wt% of P 2 O 5 . It is also preferred that the present cementitious compositions be free of quaternary ammonium silicates.
  • SiO 2 -containing material having cementitious properties is produced as a result of the following special formulation and processing steps.
  • the SiO 2 -containing materials are specially formulated to incorporate certain special metal oxides to enhance their binding properties, e.g. K 2 O and P 2 O 5 , in concentrations far higher than they would be found in conventional glass materials.
  • This composition is then mixed together to form a ceramic mix, heated and melted to a temperature of between 1500°C and 1700°C, and then rapidly cooled to form a supercooled glass structure.

  • the source of the glass material is not critical to the present invention, and may even include freshly manufactured glass, but it is preferred that the glass material be post- consumer waste glass, as this may increase the cost-effectiveness and economic viability of the presently disclosed materials as well as provide an alternative to dumping the waste glass in landfills.
  • post-consumer waste glass is meant glass that is no longer necessary to perform the function for which it was formulated and formed. Glass containers that have been emptied of a consumable product, as well as glass containers or other glass articles that are broken or no longer usable for some other reason are all examples of post-consumer waste glass.
  • Various types of crushing and grinding equipment and other like equipment can be used to produce particulate glass powders.

It is preferred that substantially all of the glass particles used in the present invention will pass through a No. 70 mesh sieve (as designated in the U.S. Sieve Series), and it is more preferred that about 80% to about 100% of the glass particles, by weight, will pass through a No. 100 mesh sieve. Particle size can be conveniently measured by using a series of vibrating screens stacked upon top of each other.
  • the glass powder and the calcined kaolin be included in the cementitious composition of the present invention so that the weight ratio of glass powder to calcined kaolin is about 20: 1 to about 1 :2, more preferably about 6:1 to about 1.5:1. It is preferred that the calcined kaolin be present as particles with a particle size in the range of about 0.1 ⁇ m to about 50 ⁇ m. Again, fine particle sizes are preferred as they increase the surface area on which reactions between the cement, calcined kaolin and glass powder can occur.
  • Kaolin is a fine, white, clay mineral, composed mostly of hydrated aluminum disilicate, commonly known as kaolinite, Al 2 Si 2 O 5 (OH) 4 nH 2 O (wherein nH 2 O is interlayer water and n is greater than 0).
  • Kaolinite consists of silicate sheets that are ionically bonded to sheets of AlO(OH) 2 .
  • "kaolin” is meant to refer to kaolin, kaolinite and other kaolin group minerals. It should additionally be noted that kaolin is often specifically designated by putting the name of the place of origin before the "kaolin", such as Korea kaolin, Georgia kaolin, New Zealand kaolin, etc.
  • calcined kaolin is a thermally activated, amorphous form of kaolin.
  • Calcined kaolin is prepared by heat treating kaolin at a temperature in the range of about 600°C to 900°C, preferably around 700°C. By heating the kaolin to this temperature the kaolin loses water by dehydoxylization, resulting in a calcined kaolin that is activated, amorphous and disordered (in both two and three dimensions), as well as highly pozzolanic.

  • the present cementitious compositions may also include optional cement additives.
  • a particularly suitable additive is a superplasticizer (also known as water-reducer).
  • Superplasticizer compounds reduce the amount of water necessary to mix with the cement composition to produce a cementitious binder of acceptable workability and thus increase the strength of concrete products formed from such cement.
  • Conventional superplasticizers include lignosulfonate derivatives, condensed naphthalene sulfonates, or carbohydrate esters.
  • POZZOLITH 440-NTM produced by Master Builders Technologies and DARACEM 100TM produced by the W.R. Grace & Co. are suitable commercially available examples of superplasticizers .
  • Other suitable additives include retardants, which delay setting time and are particularly useful for forming operations in high-temperature environments, and accelerants, which accelerate setting times and are useful for forming in low-temperature environments. Air entrainers, which improve workability, may also be used.

This binder forms a matrix in concrete or mortar products to hold together the aggregate particles. Aggregate particles are inert solid bodies that form most of the volume of a concrete article. When mixed with aggregate, the cementitious binder composition forms a binder matrix that holds the aggregate together.
  • Such solidifiable cementitious compositions are typically classified as concretes or mortars, depending on the particle size of the aggregate. Concretes usually contain both coarse and fine aggregates, whereas mortars contain fine aggregate but no coarse aggregate. The proportions of coarse and fine aggregate used in a concrete depend on the required properties and intended use, which are well-known to those of ordinary skill in the art. [0033] Aggregates for use in concrete are described in ASTM C33-90 "Standard

  • the present invention also contemplates the use of suitable inter-grinding processes, i.e., grinding of the unmixed combination of the ingredients together into a mixture, so that mixing occurs simultaneously with grinding. An example of this is when the glass material is ground into powder along with the cement clinker.

  • present formulations for cementitious compositions offer many benefits over the conventional cement compositions that are well-known in the art.
  • the calcined kaolin catalyst also contributes to long- term strength and stability. Particularly when the waste glass powder is made from soda-lime glass, the calcined kaolin provides aluminum ions that combine with the calcium, sodium, aluminum and silica compounds in the glass to form highly stable zeolite compounds, thus enhancing long-term stability.
  • the solidifiable cementitious composition in the form of mortars, concretes, and the like
  • the gain in strength is attributed to the continuous formation of additional stable calcium compounds from the lime released by the cement.

  • the cementitious compositions of the present invention that incorporate waste glass powder are also shown to have superior workability, when compared to conventional cement compositions, when they are incorporated into a concrete or mortar composition.
  • a concrete or mortar slurry with poor workability may cause air pockets to form upon solidification, thus reducing the strength of products made from the concrete or mortar.
  • This improvement in workability is believed to result from the fact that the glass powder, unlike most conventional pozzolans, is not porous and so does not absorb water. This water remains available during mixing and placing to provide lubrication for added workability.

This improved workability is highly desirable for improved placement, as discussed above.

  • Example I using waste glass powder alone resulted in a decrease in the early strength of the resulting solidified solidifable cementitious composition, while using a combination of glass powder and calcined kaolin produced a stronger solidified solidifiable cementitious composition. Further increases in the amount of calcined kaolin in the mixture led to further increases in the early strength performance. Consistent with the results of Example I, solidifiable cementitious compositions made from cementitious compositions comprising cement, glass powder and calcined kaolin (i.e., prepared according to the present invention) have substantially improved long-term and early strength performance compared to mortar and concrete products made from cementitious compositions that contain cement and glass powder, but no calcined kaolin.
