Mix ratio of m5 mixed mortar and the difference between M5 mixed mortar and cement mortar.

In the field of building construction, we may face the problem of material selection, not only the choice of product brand and price, but also the choice of mixed formula and specific content. For example, today's example of m5 mixed mortar shows that the strength grade of cement mortar is around M5. This determines the difference between it and traditional products in the field of use and scope of application. As consumers, we might as well refer to the mixture ratio of mixed mortar and the difference between M5 cement mortar and M5 mixed mortar.

What is the difference between M5 cement mortar and M5 mixed mortar?

According to JGJ/T98-20 10 Code for Mix Design of Masonry Mortar, masonry mortar can be divided into three types: cement mortar, cement mixed mortar and ready-mixed masonry mortar. The difference between cement mortar and cement mixed mortar is that cement is used as cementing material, and besides cement, lime plaster and electro-gypsum are added into cement mixed mortar.

M5 is the strength grade, which means that the strength grades of cement mortar and mixed mortar are the same, but there are also differences, such as:

Apparent density: cement mortar ≥ 1900kg/m3, mixed mortar ≥1800kg/m3;

Water retention rate: cement mortar ≥80%, mixed mortar ≥84%.

Second, the mixture ratio of mixed mortar is introduced

Wipe the interior and exterior walls mainly according to the requirements. Generally, the strength of external wall is high, and the water consumption is adjusted according to the workability of mortar.

Mortar strength M5; Cement strength is 32.5, coarse sand? Weight ratio = 1:0.56:7. 12,

Dosage per cubic meter = cement 2 12Kg? Lime plaster 1 18Kg sand 15 10Kg.

Mortar strength M5; Cement strength is 32.5, medium sand? Weight ratio = 1:0.56:6.56,

Dosage per cubic meter = cement 22 1Kg? Lime plaster124kg sand1450kg

Mortar strength M5; Cement strength is 32.5, fine sand? Weight ratio = 1:0.57:6.07,

Dosage per cubic meter = cement 229Kg? Lime plaster 13 1Kg? Sand 1390Kg

Mortar strength M7.5 cement strength 32.5, coarse sand? Weight ratio = 1:0.36:6.24,

Dosage per cubic meter = 242Kg cement? Lime paste 88Kg? Sand 15 10Kg

Mortar strength M7.5 cement strength 32.5, medium sand? Weight ratio = 1:0.37:5.78,

Dosage per cubic meter = cement 25 1Kg? Lime paste 94Kg? Sand 1450Kg

Mortar strength M7.5 cement strength 32.5, fine sand? Weight ratio = 1:0.38:5.33,

Dosage per cubic meter = cement 26 1Kg? Lime paste 99Kg? Sand 1390Kg

Mortar strength m10; Cement strength is 32.5, coarse sand? Weight ratio = 1:0.22:5.57,

Dosage per cubic meter = cement 27 1Kg? Lime paste 59Kg? Sand 15 10Kg

Mortar strength m10; Cement strength is 32.5, medium sand? Weight ratio = 1:0.22:5. 14,

Dosage per cubic meter = 282Kg cement? Lime paste 63Kg? Sand 145 kg

The first example above is about the difference between M5 cement mortar and M5 mixed mortar. It can be seen that the apparent density and water retention rate determine the respective characteristics of products, so their corresponding application fields and people are also different. In addition, we also analyzed the mixture ratio of mixed mortar. By giving examples of common schemes for reference, friends who are interested in choosing can start with reference, practice and analysis according to their own situation or actual demand budget.
