Analysis of Problems in the Application of Admixtures in Commercial Concrete!
The application of commercial concrete has been basically popularized in China, and the use of admixtures has also promoted and accelerated the development of concrete technology.
Admixtures have also solved various technical problems in the application of concrete, such as long-distance and ultra-high transportation of concrete, self compacting of concrete, and crack control of super large concrete structures.
Admixtures have been widely used in ultra-high strength and underwater non dispersing concrete.
Due to the uneven distribution of concrete material resources in our country and the limitation of green environmental protection, some regions are facing a shortage of sand and gravel aggregate resources.
As a result, many areas have to switch to using ultra-fine sand, machine-made sand, and discontinuous graded aggregates, which leads to the failure of commercial concrete to achieve the expected technical effects after the use of additives and a decrease in concrete quality.
In addition, some technical personnel in concrete production enterprises have certain misconceptions about concrete admixtures, and their improper application leads to frequent problems and even engineering accidents after using admixtures.

High ductility concrete | Breaking the curse of brittle fracture! Flexible concrete, the black technology in the construction industry
When it comes to concrete, our inherent impression is always “hard, cold, and brittle” – it is an unshakable hard block in the wall, a broken curb on the roadside, and an irreparable building hazard once cracks appear.
As the “pillar” of the construction industry, it can withstand thousands of tons of pressure, but cannot withstand even a slight bending and stretching.
The brittleness of “breaking at the first crack” has always been the fatal weakness of traditional concrete.

Heavy notice! 10 concrete companies have abnormal qualifications! It is strictly prohibited to undertake projects during the rectification
On March 30th, the Wuhan Natural Resources and Urban Rural Development Bureau announced that after verification, 10 pre mixed concrete production enterprises had abnormal professional contracting qualifications and did not meet relevant qualification standards and management regulations.
.
Which type of concrete crack is the most dangerous?
Among the types of concrete cracks, structural cracks (such as penetrating settlement cracks, load cracks, and large volume hydration heat cracks) are the most dangerous, with a width often exceeding 0.
5 millimeters and a depth penetrating the component, directly threatening the structural bearing capacity and overall stability.
.
What are the common types of concrete cracks?
The common types of cracks in concrete pouring mainly include plastic shrinkage cracks, temperature cracks, drying shrinkage cracks, settlement cracks, hydration heat cracks, and stress concentration cracks, among which plastic shrinkage and temperature cracks are the most common in the early stages of construction.
