? Saw-cut refined : This
process just removes obvious
saw cuts, but doesn’t achieve
the polish of a honed finish
to give rugged appearance.
? Acid-washed : Washing ofte
n used on limestone and
marble leaves small etching
marks
and
pits
which
produces a rustic look. Acid
washing is also used to
soften the shine on granite.
? Flamed : The surface of the
stone is heated and then
cooled quickly causing the stone to chip and pop resulting in a rough texture and slipresistant surface.
? Split-faced : Most often used in slate flooring tiles, it’s the surface the results from
hand cutting and chiseling as the stone comes out of the quarry.
? Tumbled : Marble and limestone floors are most often gives a tumbled finish. Instead
of being polished, they are buffed with an earthy finish and have a slightly pitted or a
smooth surface.
? Brushed : Brushed finish gives natural looking and worn down patina appearance to
the stone.
CONCRETE WITHOUT FIBERS
? Cracking Due to Plastic drying and hardened Shrinkage
? Lower Impact Strength
? Lower Abrasion Resistance
? Low ductility and cohesiveness
? Once cracked, concrete does not hold together, whereas fibers hold the concrete floors
together. Concrete slabs shrink due to the evaporation of moisture from the concrete
which results in linear shrinkage, to control this, use of fibers are recommended.
Synthetic Fibers increases the tensile strength of slabs, reduces slab curling, make
concrete durable with low maintenance and resistant to fire and weathering.
CONCRETE WITH SYNTHETIC FIBERS
? Improves post crack behavior
? Improves impact-and abrasion resistance
? Improves structural strength
? Improves freeze-thaw
? Improves ductility
? Improves Fire rating
? Improves cohesiveness
? Reduces curling at high dosage
? Reduces/Eliminates use of steel-reinforcement in slabs on ground
? Reduces crack widths and holds crack tightly thus improving the durability
