Microsilica - key ingredient for high performance concrete

 

With a history from the late 40's, the industrial application of silica fume (microsilica) was called the most important new product in concrete technology in the 1990's and has given civil engineers another tool in the design and construction of structures for the next century.

 

To promote microsilica in concrete is to promote high quality concrete technology and the benefits of advanced concrete materials: in terms of durable infrastructure, advanced concrete structures and sustainable high quality concrete construction.

Bridge construction, marine structures, parking structures, water supply and sewage facilities all benefit from the use of microsilica (silica fume). Likewise, the special properties of microsilica concrete give benefits in fresh concrete properties, so that rheology improvements gives benefits in terms of concrete pumping and stability of the concrete mix. Special concretes like high strength concrete, light weight concrete (LWC, LWAC), shotcrete and low permeability concretes are better made with microsilica.

 

The use of microsilica, combined with other supplementary cementing materials (SCM's), will contribute to the sustainability of concrete construction, by giving higher strength and increased use of SCM's.

 

 

LIFE-365 - new version released

(2009-11-18)

 

 

A new release of LIFE-365, version 2.01, gives the user better control of the input parameters to the service life model. Some of the default values in previous versions have been strongly debated, and while these still accompany the program, it is now easier to input the values the user has available.

Exciting structures are being built with Elkem Microsilica all the time. Of the more than 10 million cubic meters of microsilica concrete that are placed annually, Elkem is by far the largest and most experienced supplier, with a contribution to the development of microsilica stretching back 60 years
