Investigation of Plasticizing Admixtures Used in Hungarian Building Industry

Abstract:

There is no doubt that concrete makes a massive contribution to sustaining the quality of life. Properties of concrete can be expediently modified by adding special chemical materials called admixtures. Admixtures for concrete are now widely accepted as materials that contribute to the production of durable and cost-effective concrete structures [1]. Plasticizing admixtures reduce water needed to achieve a given workability of the fresh mix. This main effect can be utilized in three ways: increased strength, increased workability, or economies in mix design [2]. In this research work effect of type and dosage of different plasticizing admixtures available in Hungary were investigated in detail. Standard test methods such as flow table test, compressive test, and shrinkage test were applied to obtain effectiveness of the admixtures. Results were compared with the requirements of the harmonized admixture standard MSZ EN 934-2:2002.
