ABSTRACT:
A method for making, clean, bughole-free hardened cement structural units, including the steps of a) applying a release agent to the surface of a form; b) preparing a cement composition; c) adding to the cement composition a water-soluble polymer dispersant and a solution viscosity-reducing agent; d) placing the cement composition of step c) into the form, e) curing the cement composition of step c) to form a hardened structural unit, and f) removing the structural unit from the form.
