When a certain amount of sodium gluconate is added to the cement, it will have a very good effect on the concrete, which not only increases the plasticity and strength of the concrete, but also has a retarding effect, it means delays the initial and final solidification period of the concrete.

Chemical plants close one after another, and chemical product prices have risen by up to 50% since May,2018
The nationwide environmental protection inspection that lasted from last year has directly affected the chemical industry. Although the factory had previously adjusted prices slightly, it was far below the increase in raw materials and labor costs.
