青砖规格有哪些
青砖的规格如下: 城砖:48×24×12cm 40×20×10cm 条砖:24×12×5cm 29×14×6cm 21×14×3cm 销售纯手工:唐式、宋式、清式、各派 琉璃瓦、青砖、 仿古面砖、青砖、方砖、蓝砖、庭泥砖、枭砖、混砖等。青瓦- 筒瓦、板瓦、罗锅、折腰、滴水、脊瓦、砖雕。 青砖是粘土烧制的,粘土是某些铝硅酸矿物长时间风化的产物,具有极强的粘性而得名。将粘土用水调和后制成砖坯,放在砖窑中煅烧(900℃-1100℃,并且要持续8-15小时)便制成砖。粘土中含有铁,烧制过程中完全氧化时生成三氧化二铁呈红色,即最常用的红砖;而如果在烧制过程中加水冷却,使粘土中的铁不完全氧化(Fe3O4)则呈青色,即青砖。
青砖规格有哪几种?
青砖主要规格有:60×240×10mm、75×300×120mm、100×380mm×120mm、100×400×120mm、200×400mm×50mm、240×115×53mm、400×400×50mm。
青砖是属于烧结砖;古青砖的主要原料为粘土,粘土加水调和后,挤压成型,再入砖窑焙烤至(1000度左右),用水冷却,让粘土中的铁不完全氧化,使其具备更好的耐风化,耐水等特性。经检测古青砖的抗压大于10兆帕,吸水率小于20%,仿古青砖就是仿照古青。
扩展资料
青砖和红砖的硬度是差不多,只是烧制完后冷却 *** 不同,而红砖是自然冷却,简单一些,所以生产红砖多,青砖是水冷却(其实是一种缺氧冷却),操作起来比较麻烦,所以生产的比较少。
虽然强度、硬度差不多,但青砖在抗氧化,水化,大气侵蚀等方面性能明显优于红砖。 青砖烧制时间一般是根据窑炉大小决定;小窑(在2-2.5万块青砖左右)一般在20天(不包括饮水)饮水一般5天时间;大窑则需要30天左右。
粘土中含有铁,烧制过程中完全氧化时生成三氧化二铁呈红色,即最常用的红砖;而如果在烧制过程中加水冷却,使粘土中的铁不完全氧化(Fe3O4)则呈青色,即青砖。
青砖的标准尺寸是多少
中国标准的粘土砖尺寸是240×115×53mm,加上砌筑用灰缝的厚度8~10mm,正好4块砖长加灰缝为1m,8块砖宽加上灰缝为1m,16块砖厚加上灰缝为1m,合起来方1m3砖砌体。该模数尺寸很好,因此称其为“标准砖”。4×8×16=512(块)。砌体中每立方米需用砖512块标准砖?(砂浆用量:1-0。24×0。115×0。053×512=0。748m3)。 其它砖的模数尺寸也都是按这个思路走的。
小青砖的尺寸
常见的青砖尺寸规格有:60*240*10毫米、75*300*120毫米、100*380毫米、100*400*120毫米、200*400毫米、240*115*53毫米。青砖给人素雅、沉稳、古朴、宁静的美感,艺术形态以中国传统典
