Neutron radiation resisting barite low hydration heat concrete construction technology
The invention relates to the technical field of building construction, in particular to a neutron radiation resisting barite low hydration heat concrete construction technology. According to the neutron radiation resisting barite low hydration heat concrete construction technology, raw materials of concrete are iron sand, glass dust, heavy crystal sand, iron ore, barite, cement, mineral powder, water and a water reducing agent; the construction technology comprises the following steps of A, calculating working mix proportion; B, feeding; C, stirring; D, transporting; E, pouring; F, maintaining. The technical scheme can effectively guarantee the construction quality of the concrete, good workability, no bleeding and good mobility in concrete pouring are guaranteed, and the requirements for radiation resistance, low shrink, high density, high uniformity and the like are satisfied. When a mass concrete structure with the minimum geometric dimensioning larger than 1.2m is subjected to construction by the adoption of the technical scheme provided by the neutron radiation resisting barite low hydration heat concrete construction technology, low hydration heat of the concrete construction can be guaranteed, the temperature difference between inside and outside is lower than or equal to 20 DEG C, the adiabatic temperature rise is lower than or equal to 55 DEG C, the phenomena of honeycombs, holes, slag inclusion and cracks do not occur on the surface of the concrete, and therefore higher pouring and vibrating quality can be guaranteed.
