Abstract
A self-leveling cement mix employed for filling up and sealing excavations of channels, trenches, sewages and the like and for building works of various kinds. The cement mix includes large-sized sand of various kind having a mediangrain size of 3 mm, fine-sized sand of various kind having a median grain size of 1.5 mm, volatile ash as a remnant product of coal combustion, conventional type cement, cement aerating agent, fluidifying agent, and water.
Claims11
A self-leveling cement mix having the fluidity for completely filling up and sealing excavations of channels, trenches, sewages after the pipings, sewages have been laid, and for building works in general comprised by mixing together at ambient temperature and pressure the following components:
