Silica fume for road tunnel RPC

Silica Fume for road tunnel RPC :This silica ash rail RPC is generally used in the construction of rpc covers used in road tunnels.When RPC mixing, the amount of Microsilica and quartz sand and other fine materials in the group material should be considered to determine the feeding order, to strengthen the dispersion of fibre and to strengthen the dispersion of fine materials are the process principles that should be considered when determining the feeding order, both of which have different roles in obtaining RPC with appropriate mobility, comparatively speaking, when the amount of fine materials is large, it is necessary to give full play to the wetting and dispersing effect of water on the fine materials as a key consideration. When the amount of micro-fine materials is large, it should give full play to the wetting and dispersing effect of water on micro-fine materials as the key consideration.
