Concrete Grinding is a modern technique to eliminate trip and fall hazards. The process uses a Scarifier Concrete Grinder and Dry Surface Grinder to sand down the raised side of two joining sections of concrete. Within a matter of minutes, the raised side can be ground down permanently eliminating the "trip and fall hazard".
Shivam Cement, one of Nepal''s topranked cement producers, operates one of the most modern cement plants in the country at Hetauda. With a vision to continuously supply the domestic market with highquality ordinary Portland cement (OPC), and therefore reducing Nepal''s reliance on regular cement imports from India, the company''s focus on quality and efficient production has enabled it to ...
7 Once it is placed and compacted, the concrete must cured before it is finished to make sure that it doesn''t dry too quickly. Concrete''s strength is influenced by its moisture level during the hardening process: as the cement solidifies, the concrete shrinks.
Modern Cement Plants employ high efficiency Vertical Roller Mills (VRM''s) for material grinding and capture and recycle as much waste heat as possible. Cement is obtained by grinding the clinker and gypsum in a mill. Often a high quality limestone is added to the cement, and this can improve the performance of the cement in the final concrete.

In the next state of the process, clinker is cooled in coolers. The hot air from the coolers is returned to the preheater in order to save fuel in the overall process. The clinker is then ground to produce portland cement. Gypsum is added during the grinding process to control the set rate of the cement.
Our OK™ Mill grinding solution skilfully comminutes raw material, cement and slag. You can easily adjust it to grind any feed material and produce multiple cement types in the same mill. Due to its highly effective drying performance, the OK™ Mill is the natural choice for grinding blended cements with one or more wet components.

Polishing Process The process begins with the use of coarse diamond segments bonded in a metallic matrix. These segments are coarse enough to remove minor pits, blemishes, stains, or light coatings from the floor in preparation for final smoothing. Depending on the condition of the concrete, this initial rough grinding is generally a three to fourstep process.
Polished concrete floor surface is made by a mechanical process of grinding and polishing with the help of a penetrant chemical to provide different texture. The polishing of concrete is a multistep process which requires specialized tools and equipment. The chemical penetrant employed for ...
