Calcium lignosulphonate would reduce drying shrinkage, the influence of superplasticizer on drying shrinkage is related strongly to the water cement ratio of mortar. When the water cement ratio is lower (0.3 or 0.4), superplasticizer would increase drying shrinkage, which increases with water cement ratio decrease.

An investigation to the microstructure of worn sample of dry vibratable materials for tundish working lining after using 40 hours shows that the materials changes the properties of slag by the chemical filter, increases the viscosity of slag, forms a dense layer at slag/refactories interface, then blocks the more slag penetrate in it. The complex phase formed at the interface, such as magnesiowusite and complex spinel et al, would absorb in more low-melting point minerals, then degrade its melting point and dissolve into slag, which forms low-melting point silicate phase, penetrates into dry vibratable materials along with Monticellite and Merwinite bonding phase by diffusion.

根据使用40小时后的中间包工作层残衬结构分析，其侵蚀机理为：干式料对渗入熔渣产生化学过滤作用，增大熔渣粘度，在干式料/熔渣界面形成致密结构，阻碍熔渣的进一步渗透；随着反应的进行复合矿物中熔剂含量的增多，熔点降低，溶于熔渣形成低熔点的硅酸盐相，并沿着干式料中的钙镁橄榄石和镁蔷薇辉石等结合相向干式料基质中扩散渗透。

Because of this property, water is preferentially adsorbed by these surfaces, and large organic compounds cannot compete with strongly held water for adsorption sites on the clay surfaces. Thus, Na-clays are ine_ective sorbents for small organic molecules. However, it is possible to modify the surface properties of clays greatly by neutralizing the anionic framework of layer silicates by using positively charged organic species such as alkylammonim ions. In the modi_ed form (HDTMA-bentonite), the clay surface may become organophilic and interact strongly with organic compounds. Textile dyes represent a relatively large group of organic chemicals. In an HDTMA-bentonite-dye system it is possible that adsorption may be enhanced by the hydrophobic interaction between the adsorbed dye molecule and HDTMA-bentonite.
