When the project is to build the wall, it is generally necessary to plaster. Do you need to make a test block when making plaster mortar? What is the difference between plaster mortar and masonry mortar?

Do you need to make a test block for plaster mortar?

1. When making plaster mortar, generally speaking, you don’t need to make a mortar test block. But if it is for the exterior wall, use insulation materials for construction. When making the insulation layer, you can make a test block according to the current construction conditions. The main purpose is to detect its thermal conductivity, including whether its strength can meet the standard. Send it to the relevant department for sampling. After meeting the standard, construction can continue.

2. Plastering engineering can protect the wall. For example, reduce the impact of wind and rain. Increase the moisture-proof and heat-insulating effect of the wall. On the other hand, it can also achieve the effect of beautification. Plastering mortar on the interior wall can improve the indoor environment. Purify the air and improve the comfort of living.

Therefore, whether the plaster mortar needs to make a test block depends on the specific situation. If it is for exterior wall construction, in order to achieve a certain effect. In some cases, a test is required. But in most cases. Because the strength requirement is not high. So it can be omitted.

What is the difference between plastering mortar and masonry mortar?

1. Plastering mortar and masonry mortar are different types, mainly manifested in different uses.
If the plastering mortar you choose is basically used for plastering on the surface of the wall. It can increase the stability of the wall. It can also bring a certain decorative effect. Masonry mortar is mainly used for wall masonry, which is a cement mortar.
2. The waterproofing requirements are also different.
If it is a plastering mortar, a certain amount of waterproofing agent needs to be added to the cement mortar. It has a certain waterproofing effect. There are many types of waterproofing agents. For example, epoxy resin, etc., masonry mortar has no waterproofing requirements.
3. The strength is also different.
There is no strength requirement for plastering mortar. However, for masonry mortar, the strength requirement is still relatively high. Generally speaking, the masonry mortar model selected is the standard of m5~m10.
