| Title of the article | Prospects of application of complex additives in new generation concretes |
| Abstract. | Problem statement. The aim of the work getting the concrete of new generation with application of modern efficient modifiers. Results. Using electron microscopic and X-ray diffraction studies and the influence of superplasticizers on the structure of cement stone and obtained data on the composition of hydration products of cement. The data obtained on speed of cement hydration in the presence of Hyper plasticizers. Conclusions. It is shown that reducing the water content in the compositions with additives allows to obtain a higher strength in the later stages of hardening, but the overall picture of the kinetics of hydrate formation and participation of silicate phases in the hydration process indicates some deceleration. It is established that, despite the relatively later period of hardening, the hydration processes in cement stone in the presence of Hyper plasticizers at the initial stage slowed down and this slowing down, judging by the intensities of the separated crystalline hydrated phases, is maintained for a period of up to 6 months. In General, the new classes of additives can effectively with the aim of achieving synergy effects be used with traditional accelerators and retarders, hardening like concrete hardening under normal conditions and for «cold» concrete. |
