Influence of a Shrinkage-Reducing Admixture on the Damage to the Internal Structure of Alkali-Activated Composites during Testing of the Modulus of Elasticity KOCÁB Dalibor1,a *, BÍLEK Vlastimil Jr.2,b, TOPOLÁŘ Libor1,c, DANĚK Petr1,d, KUCHARCZYKOVÁ Barbara1,e and PŐSSL Petr1,f 1Brno University of Technology, Faculty of Civil Engineering, Veveří 331/95, 602 00 Brno, Czech Republic 2Brno University of Technology, Faculty of Chemistry, Purkyňova 464/118, 612 00 Brno, Czech Republic adalibor.kocab@vutbr.cz, bbilek@fch.vut.cz, clibor.topolar@vutbr.cz, dpetr.danek@vutbr.cz, ebarbara.kucharczykova@vutbr.cz, fpetr.possl@vutbr.cz Keywords: Modulus of elasticity, alkali-activated composite, compressive strength, acoustic emission method.
The static modulus of elasticity test was accompanied by the measurement of the acoustic activity of the material using the acoustic emission method, whose advantages is the possibility to detect early formation and propagation of cracks in the internal structure of the material.
In order to determine the influence of the shrinkage-reducing admixture on the value of the modulus of elasticity and on the damage to the internal structure of the alkali-activated composites during the testing of the modulus of elasticity in compression, 7 test specimens from each fine-grained material were produced.
Conclusion Based on the pilot measurements, it can be stated that the addition of the shrinkage-reducing admixture to AAS composite influenced the formation, development, number and size of cracks in the internal structure of the material.
Due to the volume changes, a network of microcracks was probably formed in the structure of the material with SRA, which led to a reduction of the resulting value of the modulus of elasticity.

The growth medium influenced biofilm structure; inflammatory saliva promotes its formation.
It has been demonstrated that the growth medium strongly influenced biofilm structure, i.e. inflammatory saliva promotes formation of D. desulfuricans biofilm.

The additive of Sr makes Mn ion in materials relatively compact, and this causes the distorted deformation of the materials structure.
In order to keep the chemical valence balance of locality materials, the Mn 3+ and Mn4+ will relatively congregate with each other, which caused nonhomogeneous in partial and distorted the materials structure.

Wettability of solid surfaces is a very important property and depends on both the chemical composition and geometric structure of the surface[1-2].
The structure of the protuberances has the appearance of ‘building blocks’.
This structure may enhance the capability air trapping and cause the surface to exhibit superhydrophobicity.
However, when the etching time exceeds a critical value 7 min, the building block shaped structures were destroyed by excessive etching.
