Description
Technical field
The present invention relates to and solidify the additive of water-based cement composition, described additive for mineral and solidify purposes in water-based cement composition preparing mineral, and the mineral utilizing described additive to obtain solidify cement composition.
Background technology
Within whole front 1/3 time in 20th century, it is all mix for use with some starting material immediately at the construction field (site) that the mineral of any kind solidify water-based cement composition.In steel tank or motorize mixing drum, first such as, by mummification compound (such as mineral binder, cement; And filler, such as sand; Such as, with other additive, thickening material) mix and then reach desirable consistency by adding water.
Since then, the specification of quality for material of construction improves significantly, uses industrial dry mortar to prepare material of construction at present.Dry mortar is the term of the mortar dry component mixed in the factory of material of construction manufacturers according to fixing explanation.
The basal component of this prefabricated dry mortar is mineral binder, as cement, gypsum or lime; And filler, as sand; For regulating the thickening material of rheological, for regulating the promotor of processibility and retarding agent and the water polymer powders redispersible for improvement of hardened sand pulp layer mechanical properties.
