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
Different water reducing agents have certain effects on the strength and late strength of the hardened cement paste.The high-efficiency water reducing agent can effectively reduce the mixing water consumption of the concrete mixture, and has a significant
On the question of how to add a water reducing agent, the problem worth noting is that its dosage should be scientifically controlled.Condensate will use different types of cement, and the same type of water reducer will have different types.
With the continuous evolution of human civilization, the scientific and technological knowledge is becoming more and more perfect, and the pace of electronic, informational, technical, and industrialization is striding forward. The city's high-rise buildi
Generally, the grouting method is adopted to repair the integrity cracks of building the structure. This method mainly USES pressure equipment to pour some cementing materials into concrete cracks.
