Explanation of different terms in mortar industry

With the rapid economic development in recent years and the continuous acceleration of new urban integration, the mortar industry has also ushered in the growth peak. During this period, a variety of dazzling mortar will appear in front of people, of course, it also brings a lot of confusion to entrepreneurs who are ready to invest in mortar industry. Today's editor will give you a noun explanation.

Waterproof and water resistant

The concept of waterproof and water resistance first appears in putty powder. Its water resistance means that the performance of raw materials in the environment almost does not change greatly, while waterproof means that water can not penetrate the putty. Putty is only leveling material, not waterproof material performance. In the actual application process, some enterprises exaggerate the propaganda, saying that they produce waterproof putty, and some users often ask whether the exterior wall putty is waterproof.

Bond strength and compressive strength

The bond strength mainly refers to the bonding force of mortar series products in the bottom layer. Including shear strength and tensile strength. Compressive strength refers to the ability of mortar surface with vertical action and surface tension; shear strength refers to the strength measured by applying parallel force.

The compressive strength mainly refers to the maximum value produced when the mortar is damaged by applying pressure, and the most important is the cohesive strength of mortar. High bond strength does not necessarily mean high compressive strength, and low compressive strength does not necessarily mean low bond strength.

Viscosity and strength

The higher the viscosity, the higher the strength. Strength generally refers to the physical index of mortar after curing, and viscosity refers to the state of mortar after mixing. In fact, viscosity and strength are not necessarily related. In contrast, there are many factors that affect the strength. Viscosity is generally a kind of adjustment for the viscosity of cellulose ether. The viscosity of cellulose ether used in construction is generally from 100000 to 200000, which is the most and the most widely used. Cellulose ether is selected according to the different uses of product properties, so the viscosity of cellulose has no inevitable relationship with strength.
