Application of laser particle size analyzer in ultra-fine oil well cement

Ultra-fine oil well cement is a cement with ultra-fine particle size. Its median particle size D50 can be as fine as less than 1um, reaching the sub-nano level. The maximum particle size Dmax does not exceed 18um. More than 80% of the cement has a particle size below 5um. The particle fineness level reaches Internationally advanced level of similar products. The slurry made of ultra-fine cement with this particle size has good groutability and can penetrate into the fine sand silt sand mixed layer, silt sand layer and silt layer that are generally considered impermeable to cement particles. It can be used under high water-cement ratios above 4.0 and has high sand-fixing strength under high water-cement ratios, which can meet the requirements of grouting reinforcement construction and achieve high durability and low cost.

It is an ideal high-performance ultra-fine particle cement-based grouting material. It has good permeability and groutability similar to organic chemical grouting fluids, has higher strength and durability, and is environmentally friendly and has no pollution to the surrounding environment. .

It can be used in projects such as building foundation reinforcement, building structure reinforcement, waterproofing and leakage sealing grouting of buildings, and foundation reinforcement of large equipment in complex soil geological environments, and can show excellent performance.

This time, Winner 2000ZDE is recommended for customers to measure ultra-fine oil well cement samples.
