- Abstract:
- In view of the phenomena that mixtures of lightweight concrete were prone to be in separation in condition of high fluidity，which resulted in the bad workability of mixtures，a mended L一800 rheological testing apparatus of concrete mixtures and the testing methods of concrete mixtures workability were adopted to study influences of mineral admixtures，fly ash and silicon fume，on workability of the mixtures of high flowing lightweight concreto(HFLC)，such as the value of t(40，T)，which was the time when concrete mixtures flowing the length of 40 cm at the different time intervals．slump and spread values．The results indicate that the addition of the mineral admixtures is a key measure to make the mixtures have good performances and the opti—real dosage of first grade fly ash and is 30％and 2％cement mass respectively．
