Pebble can be divided into many kinds according to their appearance and shape, there are polished and sub - light pebble. Pebbles have many kinds of color, it is natural form resembles a goose egg shaped rock, smooth surface, cement and poor bonding, mixing of concrete mixture liquidity is better, but after hardening of the concrete strength is lower. The quality is hard, the color is bright and simple, has the compression, the wear-resisting corrosion resistant natural stone characteristic, is one kind of ideal green building material.
The pebble is widely used in a variety of mechanical filters ideal cushion filter in the supporting layer. Pebble is the bottom layer; quartz sand filtering layer, fluffy cotton is adsorbed layer! Role is an initial filter, deep bed filtration, purification and adsorption. Suitable for all kinds of filter. The water chestnut like appearance, surface area, high mechanical strength, no impurities. Pebble from the color, texture up to distinguish, the best quartz pebbles, better than some areas of weathered stone better than the time of the wind will be broken for a long time. Interior decoration on the selection of Yuhua stone; paving, gardens, transformer cobblestone chosen general quartz pebbles.
