[0050] EXAMPLES Example 1: Glass-made binder component with sodium silicate as alkali activator

[0051] A glass-made binder composition using sodium silicate as an alkali activator is shown in Table 1.

[0052] Element

Dosage

glass powder 1

100 copies

Sodium silicate 2

8.53 copies

[0053] Note 1: Colorless glass powder is crushed and ground into SNAPPLE TM Glass beverage bottles were obtained by passing the glass powder particles through a No. 200 US Standard sieve.

[0054] Note 2: Sodium silicate has a silicon oxide to sodium oxide weight ratio of 1.636. This product is manufactured by PQ Corporation, Valley Forge, PA, USA as B-W TM Type 50 sodium silicate solution, solid content 42.63%, containing 3.23% Na by weight of glass powder 2 O.

[0055] According to the present invention, the glass binder components are mixed with water to form a glass binder slurry. The binder slurry is injected into a...

example 2

[0058] In contrast to the Silverstrim patent, the present invention unexpectedly finds that activation of glass activity does not require a lower modulus between 0.20:1 and 0.75:1 by weight ratio of silicon oxide to sodium oxide, thereby avoiding the use of other Components such as costly and highly corrosive sodium hydroxide. This provides the further advantages of the present invention to simplify the production process and reduce the cost of raw materials. In addition, the glass adhesive of the present invention has higher strength than other adhesives under the same curing conditions. Example 2: Comparison of the effects of different conservation conditions

[0059] The sample was made according to the proportioning in Table 1 and 29.30 parts of water were added, but the glass powder used in this example was crushed and ground Heineken (HEINEKEN TM ) beer bottles, the particles of which can pass through a No. 200 U.S. standard sieve. These samples were cured under diffe...

example 3

[0062] Sample 1 shows that the glass-based binder of the present invention develops strength much less rapidly than conventional Portland cement binders or alkali-activated slag binders. However, Sample 2 shows that after a period of time, such as the 28 days typically required for conventional Portland cement binders to achieve full strength, the glass-based binders of the present invention can achieve considerably higher strengths even under normal environmental conditions. strength. Samples 3 and 4 show that, regardless of whether there is steam or not, if heating and curing are performed, the time for the glass-made adhesive of the present invention to obtain a considerable strength will be greatly shortened. This feature is especially beneficial for precast applications where increased productivity is required. Example 3: Binder components made of glass that additionally contain additional materials

[0063] The preparation of the sample is similar to that in Table 1 in...

Abstract

The present invention relates to a binder composition comprising a glass powder with a particle size of at least less than 0.15 mm and an alkali activator containing at least one alkali metal and at least one silicate. Preferably, a sodium silicate with a SiO2:Na2O weight ratio between about 1.6:1 to about 2.0:1. Mixed with water, the binder composition can be cured at ambient temperature, but rapidly yields a very high strength at an elevated temperature between about 40° C. to about 120° C. Preferably, between about 70° C. to about 90° C. The invention further provides a method of making artificial stone using glass as a sole binder and aggregate.
