水泥砂漿襯里防腐鋼管的介紹：
Cement mortar lining antiseptic description:
水泥砂漿襯里防腐是指通常所說的1：3水泥砂漿是用1份水泥和3份砂配合,實際上忽視了水的成分,一般在0.6左右比例,即應成為0.6：1：3 ,水泥砂漿里按比例加入石子,就成為混凝土。100號水泥砂漿是指它的強度是100kg/cm2,但是現在全部改成以MPa為單位了,100號對應于M10。配合比根據原材料不同、砂漿用途不同而不同,以常用的42.5普通硅酸鹽水泥、中砂配100（M10）砌筑砂漿為例：水泥305kg：砂1.10m3：水183kg。 砂漿的標號有M3，M5，M7.5，M10，M12.5，M15，M20，M25，M30，M40幾種。砂漿按用途分有砌筑、抹灰、接縫幾種，和標號無關。
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后還有重要的一道工序，那就是風干。就是指在自然狀態(tài)下風干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!
的用途,在建筑工程中,一是基礎和墻體砌筑,用做塊狀砌體材料的粘合劑,比如砌毛石、紅磚要用水泥砂漿；二是用于室內外抹灰。
水泥砂漿在使用時,還要經常摻入一些添加劑如微沫劑、防水粉等,以改善它的和易性與粘稠度。 水泥砂漿標號強度的意思是指對按標準方法制作和養(yǎng)護的立方體試件,在28d齡期,用標準試驗方法測得的抗壓強度總體分布中的一個值。
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.
