With the increasing global awareness of environmental protection, the concept of green, environmentally friendly, and sustainable development has deeply penetrated people's hearts. In the construction industry, concrete is one of the most commonly used building materials, and the environmental issues in its preparation process have also attracted much attention. As an important additive in concrete preparation, the green development of defoamers for concrete is an inevitable trend.

The green development trend of defoamers for concrete in the future is mainly reflected in the following aspects. Firstly, environmentally friendly defoamers will become mainstream. Traditional defoamers may cause certain pollution to the environment during use, while environmentally friendly defoamers can significantly reduce the negative impact on the environment. In the future, with the increasingly strict environmental regulations and the improvement of consumer environmental awareness, environmentally friendly defoamers will gradually replace traditional defoamers and become the mainstream products in the market.

Secondly, bio based defoamers will be widely used. Biobased defoamers refer to defoamers prepared from renewable resources through methods such as biological fermentation or chemical synthesis. Compared with traditional defoamers, bio based defoamers have better biodegradability and lower toxicity, which is more in line with environmental requirements. In the future, with the continuous development of biotechnology and the reduction of costs, the application of bio based defoamers in the concrete industry will become increasingly widespread.

Finally, multifunctional and efficient defoamers will be developed. Future concrete defoamers should not only have excellent defoaming performance, but also have various other functions, such as improving the strength and durability of concrete. Meanwhile, efficient defoamers can quickly eliminate bubbles in concrete and improve production efficiency. These multifunctional and efficient defoamers will better meet the needs of the future concrete industry.

In summary, the green development trend of defoamers for concrete in the future is irreversible. Environmentally friendly, bio based, multifunctional, and efficient defoamers will become mainstream products in the market, contributing to the green development of the concrete industry.
