Product Description
JKN-LWM-550 is a high-performance hollow glass bead, mainly used as reducing agent(filling agent)in the low density cement slurry.
Characteristics
JKN-LWM-550 is a high-performance hollow glass bead with light weight, large volume, low thermal conductivity, high compressive strength, good fluidity and stable chemical performance advantages.
Normal dosage: 5%～30% (BWOC).Can be prepared for the cement slurry whose density is 1.10～1.7 0 g/cm3. JKN-LWM-550 content decreases with the increase of he cement slurry density, while the water cement ratio also decreases. Thickening time, rheological property, free water content can meet the construction requirements.
Preferred to mix without water.
