The direct consequence of poor system stability is the initiation of cracks. In particular, the early shrinkage and cracking of concrete have attracted the attention of experts and scholars all over the world. Concrete cracks have memory. If the early shr
Superplasticizer is essentially a kind of building materials, in the use of foam and bubbles and other sol bubbles, and they have different characteristics and formation mechanism, is caused by ionic superplasticizer.
The use of polycarboxylate superplasticizer concrete, compared to the use of traditional naphthalene series, aliphatic superplasticizer concrete, most of the time bleeding will be lower, less bleeding will be larger. But once the use of carboxylic acid co
Concrete is the main material in construction.In order to ensure its performance to meet the building requirements, we must strictly control the use of additives, through optimizing the performance of concrete to improve the structural stability of the bu
In practical engineering, concrete cracks caused by shrinkage are the most common. In the concrete shrinkage category, plastic shrinkage and dry shrinkage are the main causes of concrete volume deformation, and spontaneous shrinkage and carbonization shri
With the continuous improvement of society and productivity technology, in the construction industry, the quality and performance requirements of concrete are more stringent, and the quality of the building is directly affected by the performance of concr
