Almost any type of hard, durable aggregate
can be used in the preparation of Lithocrete® paving. Aggregates
that have been used successfully include: crushed rock (e.g.
granite, obsidian, quartz, serpentine, and marble), opaque
or translucent glass, gems and minerals (e.g. turquoise, agate,
obsidian, quartz, pyrite, jasper, and serpentine), sea shells,
beach pebbles, silica carbide, mica, "Pixie Dust,"
terra cotta, slate, tile, brass insets, etc.
Lithocrete's® heat-fractured glass aggregate product line
is ideal for projects that require the use of recycled materials
(see Sustainability). Recycled
glass provides a wide range of colors not typically found
with other paving materials, such as bright blues, yellows,
and red. None of the glass aggregate colors will fade under
sunlight; they naturally reflect light and have less heat
absorption. Sea shells and other materials can give a project
a natural appearance and textures, and a uniform surface with
a blend of coral sand and sea shells.
Color Consistency
Matching new add-on work is performed seamlessly using Lithocrete®.
Most of the standard series Lithocrete® aggregates are from
quarries that have good, long-term consistency characteristics.
Projects installed more than 10 years ago using Lithocrete®
paving can be matched almost perfectly today.
ASR
In the past, keeping small ASR (Alkali Silica Reaction)
or "reactive" aggregates embedded in the surface
of concrete paving was difficult. Lithocrete's® patented paving
process permanently bonds "reactive" as well as
non-reactive aggregates with lithium quartz. Lithoseal®, Lithocrete's®
patented sealer, significantly reduces the reactive condition
that may exist between cement and aggregate. To ensure minimal
maintenance, a one-time application of Lithoseal® is used.
Patents
Three US patents protect Lithocrete®: #4,748,788;
#6,016,635; #6,033,146; and U.S. Trademark #1,879,329. Lithocrete®
has a patent pending for power troweling any size surface-seeded
aggregates of a wide variety of materials. Lithocrete® also
has a patent pending for pneumatically applying surface-seeded
materials that will eliminate the common unevenness of applying
silica carbide, mica, granites, sands, and other small surface-applied
materials.
