The cement used in concrete mixtures was ordinary portland cement type I from Tasek Corporation. Berhad. Silica fume was obtained from Scancem Materials Sdn

Because of its chemical and physical properties, it is a very reactive pozzolan. Concrete containing silica fume can have very high strength and can be very durable. AEROSIL® fumed silica and SIPERNAT® specialty silica for solid agrochemical formulations Solid agrochemical formulations such as crop protection- (herbicide, insecticide, fungicide) and seed treatment-formulations (insecticide, fungicide, biocide) have been known for many years in the industry.

Scanfibre, our range of steel fibres, has become a leading brand for slabs on ground and shotcrete. Scanfibre is supported by tried and tested design methods. Scancem's silica fume is sold thoughout Asia and Australasia.

Silica fume, also known as micro silica is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 150 nm. Quick notes series for Concrete Technology from Amaze Concrete.In this part have described about Silica fume/ Micro Silica and its properties.Stay tuned, mor The microstructure can also be modified by the use of reactive aluminosilicate (mineral admixtures), such as fly ash, silica fume, or granulated blast furnace slag.These compounds contain amorphous silica and react chemically to convert calcium hydroxide to C–S–H (see Table 6).This the so-called pozzolanic reaction. In addition, slag will react cementitiously to form C–S–H directly.

It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 150 nm. The main field of application is as pozzolanic material for high performance concrete.

Scancem Materials (SM) was formed in 1993 with a head office in Australia. Initially SM was a holding company for its subsidiary Microsilica JV, a leader in the development of silica fume use in Australia and Asia. SM became involved in steel fibres in 1995 and became the leading supplier in Australia before 2000.
