MICROCONE UW is supplied as a ready to use dry powder requiring only the addition of water to produce a free flowing, non-shrink, repair material which exhibits exceptional resistance to ‘ washing out’ of the cement phase when placed in stationary or moving ater. The material is a mixture of specially processed cement, with carefully graded fine aggregate. Additives impart controlled expansion, water reduction and anti washout characteristics. The aggregate grading is designed to aid uniform mixing, minimize segregation and bleeding whilst assisting the flow characteristics.
