| 摘要 |
The invention relates to an improvement in the composition of lime, cement, concrete and mortar additives for the use of a novel physiologically acceptable deaerator system whereby it is possible to increase long-term solidity, even in constructions which can only be created in a complicated manner, avoiding disadvantageous consequences for the environment. According to the invention, tributylphosphate - which is unstable and which was previously used in an unsatisfactory manner as a deaerator- can be replaced by receptor-combined fatty alcohols, acids or esters or derivatives thereof, whereby physiological and ecological aspects can be taken into account in a more significant manner, in addition to increasing the physical constructive properties of the concrete and mortar to be treated. A combination of currently known standard-type concrete and mortar additives, polymer agents and derivatives thereof makes it possible to provide a novel deaerator.
