Analysis of structural spun concrete properties
Santrauka
Consideration is given to the spun concrete of precast reinforced concrete members of annular cross-sections. Peculiarities of technological and mechanical properties of precast spun concrete structures are analysed. Main test results of normal weight spun concrete specimens exposed to axial compression are presented. Effect of reinforcing steel bars and spirals, mix additions, aggressive temperature and salt solution actions and member age on spun concrete compressive strength is discussed.
