Abstract
Official abstract text for this publication.
Compositions and methods are presented in which aragonite, and especially oolitic aragonite particles are used as infill material in an artificial turf structure or as sub-growth substrate for natural grass. Advantageously, oolitic aragonite particles provide: a superior microporous surface for effective water saturation to impart thermal control and environmental compatibility; ammonia neutralization of urine by reducing urea hydrolysis with the free calcium presented in the aragonite particles; and aragonite particle uniformity allowing for reduced compaction and desirable water draining.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of neutralizing ammonia from urine in an artificial turf structure, comprising: providing an artificial turf structure that comprises a plurality of turf fibers coupled to a backing; and at least partially filling a space between the turf fibers with a plurality of micronized oolitic aragonite particles; wherein the micronized oolitic aragonite particles provide reactive calcium to thereby suppress ammonia volatilization from urea hydrolysis. 2. The method of claim 1 , further comprising contacting the micronized oolitic aragonite particles with water. 3. The method of claim 1 , wherein the micronized oolitic aragonite particles have an average size of between 250 micrometer and 500 micrometer. 4. The method of claim 1 , wherein the micronized oolitic aragonite particles have a surface area of at least 1.5 m 2 /g. 5. The method of claim 1 , wherein the micronized oolitic aragonite particles have a uniformity constant of between about 1.2 to about 1.8. 6. The method of claim 1 , wherein the micronized oolitic aragonite particles have a saturation constant (K sat ) of at least 50 in/hr.
