Silica Mortar

Silica mortar is composed of siliceous materials, soft clay chemical binder and admixtures. It is mainly used in coke ovens and glass kilns. Moreover, it can also be used in conjunction with silica bricks to build hot chimney equipment.

Influence of Particle Size Composition on Silica Mortar

  • Coarse particles: the gaps between coarse particles are large and the flowable part is reduced after water is adsorbed. Therefore, the increase of coarse particles usually reduces its fluidity.
  • Fine particles: fine particles can fill the gaps between coarse particles and improve the overall density of the mortar.
Mechanical Strength
  • Too many fine particles: this will increase the shrinkage of the mortar and cause cracking. This will reduce the structural strength and stability.
  • Too many coarse particles: if the proportion of coarse particles is too high, it will lead to loose bonding between particles. This will also affect the strength of the mortar.
  • Fine particles: because silica refractory mortar forms more contact points with high heat cement. Therefore, this enhances the adhesion of silica mortar.
  • Coarse particles: the contact area between coarse particles and other components is also relatively small and the adhesion is weak.
  • Uniform particle size distribution: uniform particle size distribution can improve the density of the mortar and reduce porosity. Fewer pores mean less penetration of water and other corrosive substances.
  • Uneven particle size distribution: this results in more pores within the mortar. This also increases the risk of water and chemical intrusion.

Advantages of Kerui High-Quality Silica Mortar

Excellent Fluidity

Kerui’s silica refractory mortar adopts a finely controlled particle size composition. This makes the refractory mortar easy to spread and level during the construction process. Therefore, this greatly improves the construction efficiency and quality.

High Strength and Adhesion

Kerui’s silica mortar ensures the high strength and excellent adhesion of the mortar by optimizing the fine particle content. Therefore, the increase in fine particles effectively fills the voids in the mortar and improves the overall compactness.

Excellent Durability

Like high alumina mortar, Kerui’s silica mortar has low internal porosity and strong anti-penetration ability. Therefore, our products can effectively resist the erosion of moisture and corrosive substances in the environment and extend their service life.

Superior Workability

Kerui’s siliceous mortar is also easy to mix and apply and is suitable for various complex construction environments. The optimized particle size composition reduces the construction difficulty and time cost of the mortar during the construction process.
