Notes:
Concrete is the strongest candidate to be the most important construction material of the21st century. This can be ensured by the continuous research and development of new materials andtechnologies regarding concrete construction. Properties of concrete can be expediently modified byadding special chemical materials called admixtures.In this research work effect of type and dosage of different superplasticizing admixturesavailable in Hungary were investigated in detail. Standard test methods such as flow table test andcompressive test were applied to obtain effectiveness of the admixtures. Regarding theexaminations done in the course of the research, we refer to the regulations of the EU harmonizedadmixture standard currently valid in Hungary MSZ EN 934-2:2002. In connection to that we willprecisely quote the requirements specified in the standard regarding superplasticizers and will alsomention the main differences compared to the plasticizer additives. Types, properties and use ofsuperplasticizers are introduced in detail, too. Experimental results are evaluated to rate theefficiency in compliance with the requirements of the standard
