Abstract
A cement suspension includes the following, in relation to the cement material: water (22-35% by weight); acetic acid (1-10% by weight); plasticizer (up to 8% by weight); and dispersant agent (0-2% by weight), having an apparent viscosity of 0.5-2 Pa·s for the casting speed gradient. Pieces of cement that are prepared from the suspension and which can be used as electronic components are also disclosed.
