What is concrete waterproofing agent

Recently, on Sinopec's annual results teleconference, the company representative answered questions about the oil prices, and said that the future trend of oil prices is still very uncertain, and it is expected to be around $100 this year and $85 next year respectively.

Sinopec, "There are many factors affecting oil prices at the moment, including geopolitics, macroeconomic trends, the implementation of the policy of OPEC+, the strength of the US DOLLAR and so on. We see a lot of uncertainty in the future oil prices. It is impossible to predict the accurate price, but a general trend could be estimated."

According to Sinopec, international institutions generally have a forecast of around $100 this year and around $85 next year in the oil prices. As geopolitical problems and other issues ease next year, oil prices will be lower than this year.

The volatile oil prices in the international market will continue to affect lots of industries and the supply of many products, like the concrete waterproofing agent.

What is concrete waterproofing agent?

Concrete waterproofing agent can significantly improve the impermeability and waterproofing of concrete, and the impermeability grade can reach P25 or higher. It is especially suitable for concrete for bungalow roof, large volume waterproof concrete, hydraulic concrete, waterproof mortar, etc. It can completely cure roof leakage, wall moisture return, and ground seepage.


The function of concrete waterproofing agent

1. Efficient water reduction and enhancement.

2. High-efficiency impermeability function: the addition of concrete waterproofing agent can effectively improve the capillary structure of concrete, and at the same time precipitate gel and block the internal capillary channels of concrete. Compared with no waterproofing agent, the impermeability can be improved by 5-8 times. , with permanent waterproof effect.

3. Improve the working performance of the mortar: It can improve the workability of the freshly mixed mortar, and the water loss rate is small, which can significantly improve the workability of the mortar.

4. Benefit analysis: It has the functions of replacing lime paste, overcoming hollowing, shelling, reducing floor ash, saving labor and improving efficacy.

5. Retarding effect: It can delay the heat release rate of cement hydration and effectively prevent concrete from cracking.

6. Saving cement: On the premise of maintaining the same strength and slump as the benchmark concrete, it can save 10% of cement.


Physical and chemical indicators of concrete waterproofing agent

Appearance: powdery solid; Odor: None; Corrosiveness: None


How to use concrete waterproofing agent

1. The dosage range is 4-6%, and the specific amount should be determined after a small amount of experiments.

2. For on-site mixing, first mix with stones, sand, cement and other admixtures evenly at one time, and then add water to mix. (Compared with no water repellent, the time is appropriately extended by 30 seconds.


Precautions for concrete waterproofing agent

1 When cement is changed or new cement is added, a concrete compatibility test should be done.

2. When mixed with other admixtures, its compatibility should be checked first.

3. Properly mix ingredients according to the mixing ratio, and operate in strict accordance with the construction specifications when pouring concrete.

4. As with conventional concrete, maintenance must be strengthened according to construction specifications.

5. Concrete waterproofing agent should be stored in a dry place, pay attention to moisture-proof, and the shelf life is 2 years. During the shelf life, if it is wet and agglomerated, it can still be used after being ground and sieved.

6. For concrete with water repellent in erosive medium, when the corrosion resistance coefficient is less than 0.8, anti-corrosion measures should be taken. The surface temperature of the concrete structure with waterproofing agent should not exceed 100 ℃, otherwise protection measures must be taken to cut off the heat source.


Prior to the impact of COVID-19 on the chemicals and materials industry and the price of the concrete waterproofing agent, many industry observers expected low to flat growth in 2021 in all regions outside Asia, with many countries seeing slower growth compared to recent years. Operational excellence has long been a hallmark of the concrete waterproofing agent chemical industry, and many companies are financially able to withstand short-term dips in end-market demand due to rapid leverage from reduced capex on hand.

The analysis shows that, whatever the final course of the pandemic, we can expect the inevitable long-term effects. Workplaces are expected to slowly return to pre-COVID-19 practices. Companies investing in enterprise-wide digital initiatives saw these "payoffs" in the early pandemic environment.
