The Method Design Of Limestone Mill

This kind of method can be used for large volume concrete design super over Kun Ning earth much or only required to reduce temperature rise. Water reducing agent and high grade low calcium limestone or high _ limestone compound use, replacing method in the design of concrete are able to reach the 28d age strength. Using this method the mixture ratio design of concrete increased yield, can be in the calculation of aggregate amount to offset adjustment. 

 

Add the method adding method refers to the concrete mixed with limestone, but does not reduce the dosage of cement, cement and concrete benchmarks that limestone mill in the same dosage of cement. Add method is also called external additive, is generally replaced sand with limestone, especially the use of coarse sand, gravel and sand (fine stone chip) work of poor concrete, also suitable for lean concrete, low strength and super low strength concrete on cement dosage little, workability, adhesive is used to improve the new mix of concrete the accumulation and improve the bleeding and segregation phenomenon, or to improve the use of superplasticizer and cause bleeding, segregation and reduce slump loss, or to compare several quality of limestone, limestone effect and efficiency.
