Concrete pouring works should ensure the following requirements:-Do not misrepresent the position, location of the formwork and concrete protection layer thickness of rebar. Do not use to awl beams horizontal shift in concrete formwork.-Concrete must be poured repeatedly until the completion of a certain structure as required by the design.-To avoid the stratification, the height of free fall of composite concrete when poured not exceeding 1.5 m. Case height of concrete poured is larger than 1.5 m must then use the tilt chutes or tubes of Heliotrope.-When using the chute tilt: request to closed, smooth chutes. The width of the trench is not smaller than 3-3.5 times the diameter of the largest aggregate particles. The slope of the trench should ensure to the concrete mixture is not clogged, not fast sliding born stratified phenomenon.-When using the tube: required Heliotrope tube not skewed sideways compared to the vertical approach is 0.25 m/metres in height.-Closely monitor the current state of formwork, reinforcement and momentum in the process of pouring concrete to timely handling the problem if that happens.-The degree of filling concrete into the formwork must be consistent with the calculated metrics: horizontal pressure, stiffness, retinal ... of the formwork due to new concrete pour cause.-When it rains to cover, not to rain on the concrete. In the case of irregular concrete pouring stop because of any reason, before pouring the concrete next to the handle at the surface in contact.-Pour the concrete into the night to ensure adequate light the area poured concrete.-Thickness per layer of concrete is based on the texture of each, ability to intermittent structures, structural properties and weather conditions.
