Product details

Silica fume, also known as microsilica, is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product during silicon and ferrosilicon alloy production.

According to the SiO2 content, our products can arrange form grade 85% to grade 98%. According to the bulk density, we can divide our products into densified silica fume and undensified silica fume.

(1). Silica fume in Concrete

. Can increasing strength, density

. Frost resistance, Early strength.

. abrasion resistance performance.

. anti-cavitations


(2). Silica fume in Cement

Strengthen cement impermeability.

Strengthens the fiber cement product

(3) Silica fume is used in refractory

Greatly improved products strength and high-temperature performance.


(4) Other Applications for Silica Fume

. Rubber industry

. Anti-caking industry

. Pellet binder

. Waterglass industry

Application 

Suitable for all concrete and mortar applications where the benefits of silica fume are required:

· Higher compressive strength

· Increased durability – Longer service life for structures

· Enhanced rheology – Control of mixture segregation & bleed 

Newreach Microsilica into the concrete mixer and mix thoroughly with the other mixture ingredients, adopting a procedure that ensures full dispersion of the product.  Dosage varies depending on application.  Contact Newreach for information and advice.  

 

Description

Newreach Microsilica is a dry silica fume available in two main forms.  Undensified and Densified.  In use, it acts physically as an interactive filler and chemically as a highly reactive pozzolan.  A key ingredient in many construction materials, Newreach Microsilica is used in cement products as a process aid, to improve ingredient dispersion and to improve hardened properties and overall durability.

 

Packing

Available in a range of packaging options, including:

· 25 kg paper bags & 1000 kg jumbo bags.

· Big bags in various designs & sizes

· Bulk road tanker

Please contact our representative for more details

 

Storage & handling 

Newreach Microsilica should be stored in dry conditions and not exposed to moisture.
