Development status of concrete admixture companies

At present, the overall development situation of my country's concrete admixture enterprises has the following four characteristics.

1 There are complete varieties of concrete admixtures, and product performance is constantly improving; synthetic admixture production enterprises are becoming large-scale, and the annual output value of large enterprises exceeds 1 billion yuan; automated production is becoming more and more popular. It has received more and more attention, and some companies have achieved fully automated production, and small and medium-sized enterprises also attach great importance to automated control of key processes; except for Hainan and Tibet, there are already synthetic additive production companies in the country, but the problem of unbalanced development distribution is more prominent. .

2. Similar to other industries in the field of building materials (cement, commercial concrete), the concrete admixture industry has overcapacity, low industry thresholds, and market chaos. question. According to incomplete statistics, there are more than 1,500 admixture manufacturers, including more than 350 chemical synthesis plants. There are more than 100 polycarboxylic acid-based water reducing agent manufacturers, and currently there are 53 admixture companies certified by the Ministry of Railways and qualified to supply high-speed railways. The development of the concrete admixture industry lacks unified planning and industrial policies, and industry management and market supervision need to be strengthened. After the number of concrete admixture plants exceeds market demand, the qualification approval of new concrete admixture companies needs to be strictly controlled, and blind development and repeated construction cannot cause new malicious competition.

3. The environmental protection level of concrete admixture manufacturers needs to be further improved. Most compound admixture factories have not done any sealing treatment. Synthetic naphthalene series production Odor is generated during the naphthalene melting process of the manufacturer. The floors of the compounding workshops of some admixture factories are not clean, and a lot of dust is raised when people walk.

4. Foreign companies are very concerned about the development of China's concrete admixture industry. On the one hand, they increase and expand their domestic investment in China, and on the other hand, they speed up the acquisition of domestic concrete products. The pace of admixture manufacturers.
