Abstract: In modern construction, the large volume of concrete increasing the scope of the project, to ensure the quality of mass concrete construction, in addition to meet the strength grade, impermeability requirements, the key is to strictly control the hardening process of concrete caused by the

Summary: In a modern building, bulky concrete in the size of the project is growing, and to ensure that the quality of the project, in addition to meeting promises size strength, anti-leakage requirements, concrete, and the key to strictly control the temperature inside and outside of cirrhosis caus

Abstract: In the modern architecture, the mass concrete project scale expands day by day, for guarantees in a big way The volume tong construction quality, except satisfies outside the intensity rank, the impervious request, the key must control the concrete strictly inside and outside temperature d

Summary: in modern architecture, large-volume concrete construction scale growing, in order to ensure construction quality of mass concrete except those that meet the strength, permeability resistance requirements, the key to strictly control caused by temperature difference between inside and outsi
