The ratio of cement mortar commonly used for coarse, medium and fine sand

November.18,2021

The following are three types of cement-lime mixed mortars commonly used in strength and coarse, medium and fine sand.

Fine sand can form clumps, while medium sand is difficult to form clumps and easily loosens, while coarse sand cannot form clumps at all. These characteristics also affect the application of different sands in various stages of the project.

The construction of a building cannot be separated from the wall, and the wall is made of sand. Because the thickness of the sand affects the strength of the cement mortar, the cement mortar made of fine sand has weak adsorption capacity and cannot adhere to each other, and the cost of fine sand is relatively high; too thick sand will make the cement mortar easy to crack after solidification .

Wiping internal and external walls is mainly based on requirements. Generally, the strength of external walls is higher, and the water consumption is adjusted according to the workability of the mortar.

Mortar strength M5; cement strength level 32.5, coarse sand
Weight ratio = 1:0.56:7.12, dosage per cubic meter = cement 212Kg lime paste 118Kg sand 1510Kg

Mortar strength M5; cement strength level 32.5, medium sand
Weight ratio=1:0.56:6.56, dosage per cubic meter = cement 221Kg lime paste 124Kg sand 1450Kg

Mortar strength M5; cement strength 32.5 grade, fine sand
Weight ratio = 1:0.57:6.07, dosage per cubic meter = cement 229Kg lime paste 131Kg sand 1390Kg

Mortar strength M7.5; cement strength 32.5 grade, coarse sand
Weight ratio = 1:0.36:6.24, dosage per cubic meter = cement 242Kg lime paste 88Kg sand 1510Kg

Mortar strength M7.5; cement strength 32.5 grade, medium sand
Weight ratio = 1:0.37:5.78, dosage per cubic meter = cement 251Kg lime paste 94Kg sand 1450Kg

Mortar strength M7.5; cement strength grade 32.5, fine sand
Weight ratio = 1:0.38:5.33, dosage per cubic meter = cement 261Kg lime paste 99Kg sand 1390Kg

Mortar strength M10; cement strength level 32.5, coarse sand
Weight ratio=1:0.22:5.57, dosage per cubic meter = cement 271Kg lime paste 59Kg sand 1510Kg

Mortar strength M10; cement strength level 32.5, coarse sand
Weight ratio=1:0.22:5.14, dosage per cubic meter=Cement 282Kg Lime paste 63Kg Sand 145Kg

Mortar strength M10; cement strength level 32.5, coarse sand
Weight ratio = 1:0.23:4.74, dosage per cubic meter = cement 293Kg lime paste 67Kg sand 1390Kg
