Introduction to the function and harm of mortar king

Lead: mortar king is widely used in cement mortar because of its water retention and reinforcement, thus improving the performance of cement dry prize. As construction workers, we usually add mortar king to cement to improve the efficiency of plastering and prevent cement from cracking and shelling. However, in recent years, it has been found that the use of mortar king will not only bring these beneficial effects, but also bring some harm, thus affecting our health. Next, let's take a look at the role and harm of mortar king with Bian Xiao!

Introduction: mortar king is also called rock essence, cement plasticizer and so on. It acts on cement to improve the performance of cement mortar and belongs to the category of concrete admixture. Mortar Kelly 1 uses 1000 instead of lime, which is mainly suitable for masonry and plastering of various industrial and civil buildings, and can save a lot of money for construction units.

The role of mortar king-water retention mortar king can improve the water retention of mortar. When building a wall, the water-retaining function of mortar king can ensure that the mortar is soft, has good fluidity and strong adhesion, and can reduce the ash falling on the ground, thus reducing the cost. When plastering, the requirements for the wall surface are low, and the bleeding rate is low. After being stored for 7 hours, it does not precipitate and does not need to be stirred repeatedly, which accelerates the construction speed and improves the construction efficiency.

The role of mortar king-strengthening? Mortar king has early strength effect. Mortar prepared by adding mortar king has affinity and strengthening effect with cement. By stimulating the activity of cement, it reaches a certain strength after 6 hours of use, and its durability is obviously improved compared with that of ordinary mortar, and the later strength effect is better.

Danger of Mortar King-It's very harmful to pour too much mortar. Because a large number of manufacturers will use foaming materials and polyacrylamide in the production of mortar king, with the passage of time, the strength will shrink seriously, which will make the coating and wall tiles fall off, reduce the waterproof performance of the external wall, and make the internal wall seep in the rainy season, causing the internal wall to be wet.

Danger of king of mortar-high content of infiltrated king of mortar will cause serious harm. Due to the decline of waterproof performance of external wall, alkaline substances in coating layer penetrate into baking-free brick, which will cause alkali-aggregate or alkali-bone reaction in baking-free brick. Not only that, alkaline substances will also penetrate into reinforced concrete, corrode steel bars and weaken the service life of concrete.

Harm of king of mortar-toxic and inferior king of mortar is toxic and harmful to human body. Inferior mortar king consists of three toxic substances: sodium dodecyl sulfate, sodium dodecyl benzene sulfonate and polyacrylamide. What's more, a large number of manufacturers use phosphorus-containing washing powder to produce mortar king. Presumably everyone knows that phosphorus-containing washing powder is toxic.

If the quality of mortar king is up to standard, generally using mortar king is still very beneficial to our life, which can greatly improve the performance of cement mortar, thus making the cement wall more durable and beautiful. The main reason for the harm of mortar king is that the production quality is not up to standard. As long as the production standards are strictly followed, it is just as well to use mortar king in general. Bian Xiao's explanation for today is over, hoping to let everyone know more about Mortar King.
