What is the water-cement ratio of rigid composite pile?

The water-cement ratio of rigid composite pile is 0.6- 1.0. Preferably, the precast pile adopts 42.5 ordinary portland cement, and the water cement ratio is 0.6- 1.0. Use mud hydrometer to detect the relative density of cement slurry, control the water-cement ratio, and ensure that the cement dosage meets the design requirements. The grouting amount is converted according to the volume of reinforced soil per drill, and the slurry flow is controlled by the flowmeter.
