What is concrete density agent?

1. Waterproofing agent that implements JC474 waterproofing agent standard.

The concrete siliceous compacting agent uses sulfoaluminate minerals as the expansion dense and amorphous SiO 2 components. The generated cement products are mainly Afm and Aft, supplemented by water reduction and micro air entrainment, and even Concrete internal structure. It can be adapted to the construction of concrete moisture-proof, waterproof and anti-seepage projects for ultra-long structures of more than 150m without leaving any expansion joints.

Concrete siliceous density agent makes the concrete slightly expand and dense, and has the functions of moisture-proof, waterproof, anti-seepage and anti-cracking. The anti-permeability grade of concrete mixed with this product can reach P20. The frost resistance of concrete mixed with this product can reach 300 times. This product is suitable for concrete grades C20~C60. The dosage accounts for 16% of the cement weight.

2. Polymer type

FS102 concrete waterproofing density agent is a material included in "FS101, FS102 underground rigid (composite) waterproofing technology". In actual engineering applications, FS102 concrete waterproof dense agent is mixed with concrete at 0.21% of the mass of the concrete cementitious material to form FS102 dense waterproof concrete.

The prices range from a thousand yuan to ten thousand yuan, which can be said to be quite wide.

The draft specification tends to increase the cost of 40-100 yuan per cubic meter of concrete in order to reduce later maintenance costs. If it is really effective, it should be promoted more vigorously. After all, it reduces the cost of the building Life cycle maintenance costs.

But at this stage, various products are mixed and technical standards are lacking, which will cause bad coins to drive out good coins.

Durability needs the test of time. We can only trust existing results.

Dear concrete builders, what will you do when you encounter a construction site where densifying agent must be added in the future?

Not to add, or to add?

Who knows what will happen in a few decades? Maybe the damage to buildings will be in various ways. Or perhaps as we understand the world and our technology improves, it may be possible to use concrete with densers as ordinary concrete in the future.

A little more stupid decision, the design is added, and the purchase of Party A is practical, and it will be well purchased by yourself. The fake stuff deceived. If you transfer this risk reasonably, you don't need to take such technical risks. If something goes wrong a few years later, haha, it will be enough to drink a pot. </p
