配比不同的水泥砂漿用途也不同,在水泥不變的情況下,砂用得越少標號越高。高標號用于面層,低標號的用于里層(底抹灰)樓上的。在樓地面工程中1:2的水泥砂漿比較不常用,但1:2的水泥砂漿防水效果要好一點,1:2.5和1:3的常用,多用在找平層和保護層。1:2的水泥砂漿用的水泥比較多,水化熱大了點,容易裂。具體點:1:2及砂漿主要用于抹灰面層,1:3砂漿一般用于中間層或找平層

　　The use of cement mortar varies with different proportions. In the case of constant cement, the less sand used, the higher the grade. High grade is used for the surface layer, while low grade is used for the inner layer (bottom plastering) above. 1:2 cement mortar is not commonly used in floor engineering, but it has better waterproofing effect. 1:2.5 and 1:3 are commonly used in leveling and protective layers. 1: The cement mortar of 2 uses a relatively large amount of cement, which has a high hydration heat and is prone to cracking. Specific points: 1:2 mortar is mainly used for plastering surface layer, and 1:3 mortar is generally used for intermediate layer or leveling layer

　　1、用于不同部位,M5是砌筑墻體用的砂漿;水泥砂漿1:3墻面打底砂漿。

　　1. Used for different parts, M5 is mortar used for masonry walls; Cement mortar 1:3 wall base mortar.

　　2、M5砌筑砂漿是要做試塊的;水泥砂漿1:3不發做。

　　2. M5 masonry mortar requires making test blocks; A cement mortar ratio of 1:3 will not be used.

　　3、施工時的工藝不同。粗的用于做地砌墻,細的用于粉墻等。

　　3. The construction process is different. Coarse ones are used for masonry walls, while fine ones are used for powder walls, etc.

　　砂漿強度等級是以邊長為7.07cm的立方體試塊，按標準條件[在(20±2)℃溫度、相對濕度為90%以上的條件下養護至28d的抗壓強度值確定。砌筑砂漿按抗壓強度劃分為M20、M15、M10、M7.5、M5、M2.5等六個強度等級。砂漿的強度除受砂漿本身的組成材料及配比影響外，還與基層的吸水性能有關。

　　The strength grade of mortar is determined based on the compressive strength value of a cube specimen with a side length of 7.07cm, which is cured for 28 days under standard conditions of (20 ± 2) ℃ temperature and relative humidity above 90%. Masonry mortar is divided into six strength grades based on compressive strength: M20, M15, M10, M7.5, M5, M2.5, etc. The strength of mortar is not only affected by the composition materials and proportions of the mortar itself, but also by the water absorption performance of the base layer.

　　而我們所說的M5或者M10的砂漿是指水泥砂漿強度，一般砌筑砂漿用強度表示方式表示：M5、M10、M20等常見水泥砂漿強度配合比如下：

　　And what we refer to as M5 or M10 mortar refers to the strength of cement mortar. Generally, masonry mortar is expressed in terms of strength: M5, M10, M20 and other common cement mortar strength mix proportions are as follows:

　　一般M7.5強度砂漿用于溝、井砌筑，M10的強度砂漿用于毛石、擋墻砌筑。

　　Generally, M7.5 strength mortar is used for trench and well masonry, while M10 strength mortar is used for rubble and retaining wall masonry.

　　一般高速公路修建排水溝使用M7.5強度等級的砌筑砂漿。水泥砂漿強度等級被劃分為了6個等級他們分別是m2.5、m5、m7.5、m10、m15、m20,而用處的話

　　Generally, M7.5 strength grade masonry mortar is used for the construction of drainage ditches on highways. The strength grade of cement mortar is divided into six grades, which are m2.5, m5, m7.5, m10, m15, m20, and are used for various purposes

　　一般情況下多層建筑物墻體選用M2.5-M15的水泥砂漿、檢查井、雨水井等砌體,常采M5砂漿、變電所、地下室等砌體選用M2.5-M10的水泥砂漿;

　　In general, M2.5-M15 cement mortar is used for the walls of multi story buildings, as well as for the masonry of inspection wells, rainwater wells, etc. M5 mortar is commonly used, and M2.5-M10 cement mortar is used for the masonry of substations, basements, etc;

　　二層以下建筑常用M2.5以下砂漿公路修建排水溝使用M7.5強度等級的水泥砂漿。而你裝修打地平或者是浴室的話建議用m7.5強度等級的水泥砂漿。

　　Buildings below the second floor commonly use cement mortar with a strength grade of M7.5 for road construction and drainage ditches. If you are decorating the floor or bathroom, it is recommended to use M7.5 strength grade cement mortar.

　　通常所說的1：3水泥砂漿是用1重量水泥和3重量砂配合，實際上忽視了水的成分，一般在0.6左右比例，即應成為1：3：0.6，水泥砂漿的密度為2000Kg/m3。

　　The commonly referred 1:3 cement mortar is a mixture of 1 weight of cement and 3 weight of sand, which actually ignores the composition of water. The ratio is generally around 0.6, which should be 1:3:0.6. The density of cement mortar is 2000Kg/m3.

　　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1:3:0.6,水泥砂漿的密度為2000Kg/m3.

　　The commonly referred 1:3 cement mortar is a mixture of 1 part cement and 3 parts sand, which actually ignores the composition of water. The ratio is generally around 0.6, which should be 1:3:0.6. The density of cement mortar is 2000Kg/m3

　　一般抹灰砂漿用配合比表示：1:1、1:2.5等。

　　Generally, the mix proportions for plastering mortar are expressed as 1:1, 1:2.5, etc.

　　用途：

　　Purpose:

　　砌各種隔斷墻和各類砌體使用1：2的水泥砂漿;墻面抹灰以及封閉管道、線路、修補等，使用1：1水泥砂漿;

　　Use 1:2 cement mortar for building various partition walls and masonry structures; Wall plastering and sealing of pipelines, lines, repairs, etc., using 1:1 cement mortar;

　　地面找平使用1：1水泥砂漿，并且要求用純水泥收漿;

　　Use 1:1 cement mortar for ground leveling, and require the use of pure cement for grouting;

　　貼墻磚使用2：1水泥砂漿，不能使用純水泥貼墻磚;鋪地磚要使用1：3水泥砂漿，并且砂漿不能過稀;

　　Use 2:1 cement mortar for wall tiling, and do not use pure cement for wall tiling; When laying floor tiles, a 1:3 cement mortar should be used, and the mortar should not be too thin;

　　水泥砂漿強度M5或者M10等和1:2或者1:3水泥砂漿，兩者是不是同一概念，也沒有必然聯系。砌筑時常用強度表示，抹灰時常用配合比表示，但是農村一般情況不會分那么清，很多地方都是用配合比表示。

　　Is the strength of cement mortar M5 or M10 the same as that of 1:2 or 1:3 cement mortar, and there is no necessary connection between the two. Strength is commonly used in masonry, and mix proportion is commonly used in plastering, but in rural areas, it is generally not so clear, and many places are expressed using mix proportion.
