- Abstract
The article analyses what effect crystallization additive usage has on concrete physical and mechanical properties and shrinkage to find most effective concrete additive. Investigations of concrete properties with various amounts of crystallization admixture were performed. 9 concrete mixtures with different amounts of crystallizing admixtures were formed and admixtures were added to the concrete mixes from 0.6% to 1.4% of the cement mass, in increments of 0.1%. During the research, the influence of the amount of crystallization admixture the density of hardened concrete, flexural strength, compressive strength, and shrinkage was determined. After evaluating the physical, mechanical properties and shrinkage of the concrete, it was determined that the optimal amount of crystallizing admixture in the concrete mixture is 1% of the cement mass. Thus, it can be argued that the use of a crystallizing admixture has a positive effect i.e., reduces the shrinkage of concrete, because of which cracks in concrete structures can be avoided.
