水泥砂漿襯裏防腐的介紹:
Cement mortar lining antiseptic description:
 
水泥砂浆衬里防腐是指通常所说的1:3水泥砂浆是用1份水泥和3份砂配合,实际上忽视了水的成分,一般在0.6左右比例,即应成为0.6:1:3 ,水泥砂浆里按比例加入石子,就成为混凝土。100号水泥砂浆是指它的强度是100kg/cm2,但是现在全部改成以MPa为单位了,100号对应于M10。配合比根据原材料不同、砂浆用途不同而不同,以常用的42.5普通硅酸盐水泥、中砂配100(M10)砌筑砂浆为例:水泥305kg:砂1.10m3:水183kg。 砂浆的标号有M3,M5,M7.5,M10,M12.5,M15,M20,M25,M30,M40几种。砂浆按用途分有砌筑、抹灰、接缝几种,和标号无关。
Cement mortar lining of said preservative is typically 1:3 cement mortar with 1 part of cement and 3 parts sand with, in fact neglected water composition, the proportion of generally about 0.6, which should be 0.6:1:3, cement mortar in proportion to join stones to become concrete. 100 refers to its cement mortar strength 100kg/cm2, but now all changed in MPa, and 100 correspond to the M10. Mix according to different raw materials, mortar for different purposes and different to usual 42.5 ordinary portland cement, medium sand with 100 (M10) masonry mortar as an example: cement 305kg: sand 1.10m3: Water 183kg. Mortar label has M3, M5, M7.5, M10, M12.5, M15, M20, M25, M30, M40 several. By use of a mortar masonry, plastering, several seams, and the label has nothing to do.
 
水泥砂漿防腐工作完成後還有最重要的一道工序,那就是風幹。就是指在自然狀態下風幹2-3天。主要是防止在裝運的途中由于顛簸導致水泥砂漿出現裂縫!
Upon completion of cement mortar corrosion and most importantly, a process that is dry. Refers to air-dry in a natural state for 2-3 days. Is to prevent the shipment of the way as bumps, cracks resulting cement mortar!
 
水泥砂浆防腐鋼管的用途,在建筑工程中,一是基础和墙体砌筑,用做块状砌体材料的粘合剂,比如砌毛石、红砖要用水泥砂浆;二是用于室内外抹灰。   
 
Use cement mortar coating pipe, in construction, one is the foundation and wall masonry, adhesives do massive masonry materials, such as rubble, brick to use cement mortar; two is used for indoor and outdoor.
 
水泥砂浆在使用时,还要经常掺入一些添加剂如微沫剂、防水粉等,以改善它的和易性与粘稠度。 水泥砂浆标号强度的意思是指对按标准方法制作和养护的立方体试件,在28d龄期,用标准试验方法测得的抗压强度总体分布中的一个值。
Cement mortar when in use, they often incorporate additives such as micro-foam agents, waterproofing powder to improve its workability and viscosity. Reference numeral strength of cement mortar is meant by standard methods for the production and conservation of the cube specimens, the age 28d, as measured by standard test method for compressive strength of the overall distribution of a value.
