بیشترMechanically Polished Concrete. Polished Concrete is achieved by the process of grinding the surface of the concrete, to expose the desired amount of aggregate, hardening the surface and filling the tiny air holes, allowing the surface to be polished to the desired finish ranging from Matte to High Gloss.
بیشترHowever, surprisingly the desired properties could be achieved with these cement types, if the grinding aid used according to the invention was used. In the preparation of a cement, cement grinding occurs. The cement grinding is used in particular to form a reactive product from the clinker and optionally from the additional main constituents.
بیشترThe desired aesthetic results are achieved just by grinding and polishing concrete floors. Additionally, considering the fact that polished floors require minimal maintenance, expenses are kept at a minimum. Tools Needed to Grind Concrete Floors. Having the right concrete floor grinding tools is essential for achieving a perfectly polished floor.
بیشترThere is potential to optimise conventional cement clinker grinding circuits and in the last decade significant progress has been achieved. The increasing demand for "finer cement" products, and the need for reduction in energy consumption and green house gas emissions, reinforces the need for grinding optimisation.
بیشترThe high-speed machines are loud and can send concrete rubble flying from the grinding wheel. Grinding concrete also releases fine silica dust, which can cause health problems. Always wear a NIOSH-certified N95-rated respirator. Check the seal with this easy test: If you can exhale and inhale sharply without air escaping, you're good to grind.
بیشتر5. Polishing the surface. After a smooth, level surface has be achieved through grinding and sealing, polishing of the concrete slab can commence. The polishing process begins by applying a low-grit diamond resin pad. This continues, progressing in grit levels, until the desired level of polish is achieved.
