鹅卵石，作为一种纯天然的石材，取自经历过千万年前的地壳运动后由古老河床隆起产生的砂石山中，经历着山洪冲击、流水搬运过程中不断的挤压、摩擦。在数万年沧桑演变过程中，它们饱经浪打水冲的运动，被砾石碰撞摩擦失去了不规则的棱角，又和泥沙一道被深埋在地下沉默了千百万年。鹅卵石主要化学成分是二氧化硅，其次是少量的氧化铁和微量的锰、铜、铝、镁等元素及化合物。它们本身具有不同的色素，如赤红者为铁，蓝者为铜，紫者为锰，黄色半透明为二氧化硅胶体石髓，翡翠色含绿色矿物等等；由于这些色素离子溶入二氧化硅热液中的种类和含量不同，因而呈现出浓淡、深浅变化万千的色彩，使鹅卵石呈现出黑、白、黄、红、墨绿、青灰等色系。鹅卵石种类 用途鹅卵石产品有：天然颜色的机制鹅卵石、河卵石、雨花石、干粘石、喷刷石、造景石、木化石、文化石、天然色理石米等建筑装饰材料及室内装饰用的高级染色沙，无毒、无味、不脱色。品质坚硬，色泽鲜明古朴，具有抗压、耐磨耐腐蚀的天然石特性，是一种理想的绿色建筑材料。
Cobblestone use:
Pebbles are widely used in public buildings, villas, garden buildings, laying roads, parks, rockery, bonsai filling materials, garden art and other high-level superstructure. It carry forward the ancient oriental culture, in turn, Western classical, elegant, a return to basics style.
Pebbles also clean water, sewage, electricity, garden project to provide high quality materials other items. Also ceramics, precision casting, papermaking, abrasion, chemical, silicon, providing raw materials and national defense.
Performance parameters: surface finish 98%, compressive strength over the 600 Kg/M2. Transformers cobblestone standard ministerial standards under the Ministry of Construction and large oil-immersed transformers should have oil storage tank bottom area of flat to slightly larger share of the transformer, the depth of about 1M, the laying of about 8-10CM diameter pebbles, the main purpose of is the absorption of transformer oil leakage.
