LTS-1 replenishment of pumping concrete of densitied silica fume can markedly improve the pumpability of pumping concrete and obviously increase the quality and strength of hardened concrete.

The influences of mixing silicon ash and fly ash on strength of high-performance cementing material

Starting with how the cement simply mixed with different amount of ultra-fine f ly ash,silicon ash and the compound of ultra-fine fly ash and silicon ash will affect the compatibility of the cement and the superplasticizer,this paper anal yzes the influential mechanism of mineral admixture on the compatibility of the cement and the superplasticizer at low water binder ratio.

By using the solid layer methods,the experimental results show that not only non-soluble deposit density but also equivalent salt deposit density and the flashover voltage are affected by the Kieselguhr consistence under the same salt consistence.

A large number of studies about the influence of the equivalent salt deposit density(ESDD)on AC flashover voltage of polluted insulators have been done home and abroad,but few study done about the influence of the non-soluble deposit density(NSDD)on it is done.

It may be related with the pollution test method in which the non-soluble deposit density(NSDD)does not be included.
