On the strength of the fujian ceramic tile seam filling agent

Intensity of ceramic tile gap filling agent of fujian province at the end of the day, from gelled material hydration hardening as cement. Gelled material after hydration material generated, leaving is not a grain of a grain of cement particle swam toward liquid matrix, but immediately bonded interweave each other, become a three-dimensional network structure, the strength and there is still a deformation capacity of the network structure of the material, on the intersection in a solid key link, this just formed to strength the basic unit of ceramic tile gap filling agent - — Gelation. This interaction can be referred to as the solid keys, intersection point can be called a consolidation. In another part of the intersection, there may be a small liquid mediation layer, van der Waals force by the liquid, when stress may be a slow slip. On u pull, you can disable it ( Disconnect) , on the contrary, if the pressure, regardless of size, can cause damage. In aqueous gelling fundamental influence on strength at the same time, don't ignore an important factor, this is the dense particles fill, fill the space to form a high strength is important. Multiphase material for fujian ceramic tile gap filling agent, the microstructure of each component phase of porosity affects the strength of the ceramic tile seam filling agent. General dense and hard natural aggregate, and cement matrix and interface transition zone between coarse aggregate porosity usually determines the strength of the ordinary ceramic tile seam filling agent.
