In the home, the living room and bedroom decor should use warm colors to show a warm, comfortable atmosphere; while for bathroom, kitchen decor should choose an elegant Eau cool shades to show the clean. 石材特性： 1.天然材質 光亮晶瑩、堅硬永久、高貴典雅。 2．耐火性 各種石材皆不同，有些石材在高溫作用下，發生化學分解。 （1）石膏：在大于 107 ℃時分解。 （2）石灰石、大理石：在大于 910℃時分解。 （3）花崗石：在 600℃時因組成礦物受熱不均而裂開。 3．膨脹及收縮 石材也是熱脹冷縮，但若受熱后再冷卻，其收縮不能回復至原來體積，而必保 留一部份成為永久性膨脹；美國兵工廠曾試驗由0℃至 100℃，再降到0℃，測 出永久膨脹增加之度為0.02—O.045%。 4．耐凍性 到攝氏零下 20時，發生凍結，孔隙內水份膨脹比原有體積大1/10，巖石若不能 抵抗此種膨脹所發生之力，便會出現破壞現象。一般若吸水率小于 0.5%，就不 考慮其抗凍性能。 5．耐久性 石材具有良好的耐久性，用石材建造的結構物具有永久保存的可能。古代人早 就認識到這一點，因此許多重要的建筑物及紀念性構筑物都是使用石材建筑的 。 6．抗壓強度 石材的抗壓強度會因礦物成份、結晶粗細、膠結物質的均勻性、荷重面積、荷 重作用與解理所成角度等因素，而有所不同。若其他條件相同，通常結晶顆粒 細小而彼此粘結一起的致密材料，具有較高強度。致密的火山巖在干燥及飽和 水份後，抗壓強度并無差異（吸水率極低），若屬多孔性及怕水之膠結巖石， 其干燥及潮濕之強度，就有顯著差別。 Stone features: 1 natural materials Bright crystal clear, hard and permanent, elegant. 2. Fire resistance Are different kinds of stone, some stone under high temperature, chemical decomposition. (1) Gypsum: greater than 107 ℃ decomposition. (2) Limestone, marble: decomposition at greater than 910 ℃. (3) Granite: at 600 ℃ due to uneven heating and split constituent minerals. 3. Expansion and contraction Stone is thermal expansion and contraction, but if heated after cooling, the contraction can not return to its original volume, and will keep a part of a permanent expansion; U.S. arsenal has experimented with the 0 ℃ to 100 ℃, and then down to 0 ℃, measure the increase in the degree of permanent expansion of 0.02 -O.045%. 4. Freezing tolerance Celsius to minus 20, the occurrence of frozen water within the pore volume expansion ratio of the original large 1/10, can not resist such a rock if the power of expansion that occurs, there will be damage phenomena. If the water absorption of less than 0.5% of the general, do not consider their frost resistance. 5. Durability Stone has good durability, with a stone built construction with the possibility of permanent preservation. Ancient people have long recognized this, so many important buildings and monumental structures are the use of stone buildings. 6. Compressive strength The compressive strength of the stone due to minerals, crystal thickness, cement material uniformity, load size, load acting cleaved so that the angle and other factors vary. If other conditions are the same, usually small crystalline particles bonded to each other along the dense material with high strength. Dense volcanic rock in dry and saturated water, the compressive strength did not differ (low water absorption), if they are afraid of the water in the porous and cemented rocks, the strength of its dry and damp, there are significant differences.
