Massive concrete composition design

U ovom završnom radu, općenito je opisan proces projektiranja sastava betona kao građevinskog materijala.Opisane su glavne karakteristike betona koje utječu na samu izvedbu poput čvrstoće i obradljivosti na koje možemo utjecati raznim postupcima i prilagodbama koje su opisane u radu. Jedna od glavnih problema masivnog betona je stvaranje površinskih pukotina pri sušenju i procesu hidratacije cementa. Sukladno opisanoj problematici su opisani načini projektiranja sastava uz pomoć korištenja kemijskih i mineralnih dodataka, modifikacijom količine cementa čime se utječe na smanjenje broja pukotina. Opisana su ispitivanja u kojima su navedeni i dokazani najbolji načini riješavanja istog problema.In this final paper, the process of designing concrete composition as a construction material is generally described. The main characteristics of concrete that affect the performance itself, such as strength and workability, which can be influenced by various procedures and adjustments described in the paper, are described. One of the main problems of solid concrete is the formation of surface cracks during drying and cement's hydration process. In accordance with the described problem, the methods of designing the composition are described with the help of using chemical and mineral additives by modifying the amount of cement, which affects the reduction of the number of cracks. Tests are described in which the best ways to solve the same problem are specified and proven
