Concrete plays an important role in the construction of modern engineering. However, the cracks in concrete are more common, and the cracks in the bridge engineering are almost everywhere. Although various measures are taken during the construction, the cracks still occur. In mass concrete, the temperature stress and temperature control are great significance. First of

1. self contraction. Due to the high performance concrete in water evaporation and condensation of microtubule contraction, make the concrete surface fission, anti-carbonation of high performance concrete, freeze-thaw cycle effect and anti chloride ion diffusion is disadvantageous, reduces the durability of high performance concrete; 2. The surface crack caused by wet expansion. High performance concrete

Silica Fume is widely used in refractory industry. The practical application in the following aspects: 1.Instead of pure aluminum oxidation mud as refractory materials 2. As additive production in amorphous and shaped refractory products, greatly improve strength, high temperature performance. 3. Used as coagulant agent in the pouring of steel barrel’s monolithic lining. 4. As

Silica fume can be used either as a densified or undensified powder, a slurry, as combination at the concrete mixer, or part of a factory-blended cement. Generally, the comparisons are made against a concrete made with 100% CEM I (Portland cement). The following terms are used with specific meanings: – blending: mixing together cementitious components

920 silica fume can fill the porosity of the cement particles, and at the same time generate gel with hydration products, reacts gel with alkaline material- magnesium oxide. In concrete and mortar, mixed with right amount of silica fume, can play a role as follows: 1. Improve compressive strength, bending, anti-permeability, anticorrosive, impact resistance and

Zirconia silica fume is a compound of zirconium dioxide, zirconium oxide melting products. The production of silicon-zirconium off special device which used to collect the silica powder, not only has the general characteristics of sillca, but also a certain amount of zirconia powder. Zirconia silica has a special use in the field of refractories ,
