The consistency of a fresh cement paste, which is formed after mixing Portland cement with water, depends significantly on the water to cement ratio (w/c), the cement fineness and its composition, but also on the other parameters as temperature of cement and water. The paper is focused on researching the influence of increased temperature of cement and water on the fresh cement paste consistency. Various cement pastes with different w/c ratio (0.28, 0.32 and 0.36) and different temperatures of water and cement (20±2°C, 40°C, 60°C) were investigated. The consistency of cement paste was measured by Vicat roller penetration method. The tendency of losing the consistency of the fresh cement paste with increasing of its temperature was observed and exhibited as linear correlation with the coefficient of determination R 2 (0.28) = 0.9695 and R 2 (0.32) = 0.9147 respectively.
