Are Pebbles Rocks


Pebbles refer to the particles with a diameter greater than 5mm formed by natural conditions of rocks.Pebbles are formed gradually over a long period of time.The formation of pebbles can be divided into two stages.The second stage is when rocks are carried and rounded in the river.


Pebbles are naturally formed angular - free rock grains that can form conglomerate.It is divided into river pebbles, sea pebbles and mountain pebbles.The shape of the pebble is mostly round, the surface is smooth, the bond with cement is poor, the mixture of mixed concrete has good fluidity, but the strength of hardened concrete is low.

(1) natural cobblestones for transformer of power plant: 5-8cm, 8-12cm;The electric power department passed all the tests.
(2) cobblestone filter material series :2 -- 4mm, 4 -- 8, 8 -- 16mm, 16 -- 24, 24 -- 32 mm;(for filter water only).
(3) landscape pavement engineering series :1 -- 3cm, 3 -- 5cm, 5 -- 8, 8 -- 16, 16 -- 25, 25 -- 40;(for paving roads).
(4) water treatment cushion series: 2 -- 3cm, 3 -- 5cm, 5--8, 8 -- 16, 16 -- 32;(for water treatment plant, sewage treatment plant).
(5) chemical plant series: black natural pebbles, specifications: 5-8cm, 8-12cm;(strong acid resistance and corrosion resistance)


The use of pebbles: pebbles are widely used in power plant transformer, water treatment filter material cushion, public buildings, villas, yards, garden pavement laying, river embankment, lake bottom, chemical plant, sewage plant, steel mills, waterworks and other projects, is the best choice of excellent materials.
