Analysis Of Slump Loss in Ready-mixed Concrete

With the continuous progress of construction technology, the requirements for concrete are getting higher and higher. Concrete slump loss is a problem often encountered in the use of commercial concrete, especially the pumping concrete problem is more prominent, has seriously affected the construction quality. Therefore, it is necessary to analyze the loss of ready-mixed concrete slump in depth.
The reasons for the loss of concrete slump are multifaceted, and these factors are interrelated. They mainly include four aspects: first, cement, such as the type of mineral components in cement, the content of different mineral components, alkali content, fineness, particle grading, etc.; second, admixtures, such as the amount of loss on burning, etc.; third, aggregates, such as grading, mud content, water absorption, etc.; fourth, chemical admixtures, such as the chemical composition of high-efficiency water-reducing additives, molecular weight, the degree of vulcanization, the balance of the concentration of ions, and the amount of dosage; and fifth, the environmental conditions, such as temperature, humidity, and the amount of water absorption; and fifth, the environmental conditions, such as temperature, humidity, and the amount of water. Environmental conditions, such as temperature, humidity, and transportation time.
