Abstract

Carried out the pump concrete mix optimizing tests for Jinping II diversion tunnels secondary lining by preference tests of 4 kinds of fly ash, comparison tests of 7 kinds of water reducing agent, mixing with air-entraining agent, mixing with different kinds of cement, parameters selection test of standard mix proportion, relative test of strength and water-glue ratio, etc. On base of these optimizing tests, a series of technical measures have been applied to reduce unit water consumption and cementitious material consumption of concrete, improve performances of fresh mixed concrete and hardened concrete, meet the requirements of long transportation time, and increase the economy and duration of concrete. It is a good reference for other project to solve the difficulties of pump concrete long time transporting.
