For over 35-years Norchem has built a strong reputation for outstanding technical expertise, superior customer support and the highest level of quality. Norchem silica fume is in use all over the globe by many of the world’s most respected construction companies – and in a board range of other cementitious applications including, concrete roofing tile, gypsum & cement wallboards, fibre-cement products, refractories, oil well grouts and cementitious repair products. High Performance Concrete (HPC) containing silica fume greatly enhances durability, HPC produced with silica fume delivers increased toughness; increased resistance to abrasion, corrosion and chemicals; and life-cycle cost efficiencies. Highway bridges, parking decks, marine structures and bridge deck overlays are subject to constant deterioration caused by rebar corrosion, abrasion and chemical attack. Silica fume will protect concrete against deicing salts, seawater and abrasion from road traffic. Rebar corrosion activity and concrete deterioration are virtually eliminated and greatly minimizing maintenance costs. High-strength concrete enhanced with silica fume provides architects and engineers with greater design flexibility. Traditionally used in high-rise buildings for the benefit of smaller columns (increasing the usable space) high-strength concrete containing silica fume is often used in precast and pre-stressed girders allowing longer spans in structural bridge designs.
