In order to improve the uniformity of fresh foamed concrete slurry and reduce the temperature difference stress, the following measures are put forward, which can effectively reduce the foam mixing.
Spring is the time when everything comes back to life. Everything is new and alive. Do you have any new plans for spring? Tong run invites you to enjoy peonies together and make a fortune. Speaking of luoyang, you may be familiar with it. Luoyang is the o
Concrete admixtures are essential components of high performance concrete. The selection of admixtures directly affects the functional properties of concrete.However, in order to achieve the expected performance of concrete, it is necessary to understand
Foaming agents play an important role in different fields, such as porous materials, cosmetics, food, fire fighting and oil recovery.There are many kinds of foaming agents, and their performance evaluation indexes are mainly foamability and stability.
The standard of cement foaming agent mainly depends on the foaming times of cement foaming agent and the stabilizing effect of foaming agent. These are the two most important indicators we are looking at right now.
At present, the external thermal insulation material of the external wall is mainly organic thermal insulation material based on polystyrene foam board and polyurethane foam, which has the characteristics of inflammability, flashover, fierce fire and smok
