| Abstract: | Synthesized a novel solid lightening agent DJ-2 from materials modified by surfactants and bulking agents. The results showed that density of the solid low-density cement was stable and water loss was controlled by optimized the fluid loss agent. The compressive strength and flexural strength of solid lowdensity cement were 20% and 11% higher than floater low-density cement after curing 72 h at 75 ℃. |
