The common five mortar mix ratio explanation, according to the "masonry mortar mix ratio design regulations" (JGJ98-2000) the following proportion is based on the weight unit。According to the different needs of the building, M5 and M7 are separated.5, M10, C20, C25 ratio of several kinds of cement mortar, then the nextSichuan wet mix waterproof mortarThe manufacturer takes you to carefully understand the mix of these five kinds of mortar, and I hope it will be useful to you!

First, the mix of M5 cement mortar:

Cement: Medium sand = 1:5.23。

Conditions: Construction level, general;Sand, medium sand;Sand moisture content: 2.5%;Actual cement strength: 32.5 MPa

二、M7.5 Mix ratio of cement mortar:

The proportion of the dosage of each material in the trial allocation of mortar: cement: sand =260∶1541= 1:5.93

Condition: Cement mortar used for laying ditches and Wells, strength M7.5, the consistency is 30~50mm。Main parameters of raw materials, cement: 32.Grade 5 cement;Medium sand, packing density of 1541kg/m3;Construction level: average。

The cement amount is 260kg/m3, sand amount QS=1541kg/m3, and water amount is 280kg/m3

Third, M10 cement mortar mix:

The dosage ratio of each material of mortar: cement: sand =240∶1221= 1:5.09

Condition: Cement mortar used for laying rubble retaining wall, strength M10, consistency 30~50mm。Main parameters of raw materials, cement: 32.Grade 5 cement;Medium sand, packing density of 1221kg/m3;Construction level: average。

Cement content 240kg/m3, sand content QS=1221kg/m3, water content 290kg/m3

4, C20 concrete mix: cement: sand: gravel: water = 1:1.83：4.09：0.50

Conditions: Slump 35--50mm;Sand type: coarse sand, preparation strength: 28.2MPa;Stone: river stone;Larger particle size: 31.5mm;Cement strength grade 32.5, actual strength 35.0MPa .

Cement content per cubic meter of concrete: 326Kg;Sand content: 598Kg;Crushed stone: 1332Kg

5, C25 concrete mix: cement: sand: gravel: water =1:1.48:3.63:0.44

Conditions: Slump 35--50mm;Sand type: coarse sand, preparation strength: 28.2MPa;Stone: river stone (pebble);Larger particle size: 31.5mm;Cement strength grade 32.5, actual strength 35.0MPa .

In each cubic meter of concrete, cement content: 370Kg;Sand content: 549Kg;Crushed stone: 1344Kg

These are M5 and M7.5, M10, C20, C25 ratio of cement mortar。The mix ratio can be adjusted according to actual conditions。Sichuan Construction Building Materials Co., Ltd. is a professional engaged in Chengdu wet mix mortar production, sales and transportation, my company has a professional team, and mature technology, rich experience!
