Information × Registration Number 0208U005468, 0107U001874 , R & D reports Title To develop concrete curing accelerator, which provide high initial strength for operative repair of reinforced transport structures. popup.stage_title Head Fal Andrey, Registration Date 23-05-2008 Organization State Highway Scientific Research Institute popup.description2 Object of research - technological operating properties of concrete solution mix, modified of complex additives, which contain the accelerator of hardening. Aim of work - research of properties of modified cement concrete and development of complex additives for cement-concrete with high original strength. Method of research is theoretical and research. As a result of review of scientific-research literature factors are determined, influencing on strength and character of increasing strength of cement-concrete on early stages of hardening. It is determined functional purpose and also requirements for composition of complex additives of concrete mixes for cement-concretes with high original strength. It is determined the choice of accelerator of hardening cement and organic joins, which increases effectiveness of accelerators of hardening. Laboratory samples of complex additives - accelerator of hardening are made, and optimization of composition of additives is carried out. It is determined technological and physics-mechanical characteristics of samples of new made solute mixes and cement-concrete.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
