Abstract

The invention discloses a concrete mixture which is applicable to the cast-place construction controlled by slump flow, as well as the construction method thereof. The components of the concrete mixture comprise by weight parts as follows: 250 to 270 kilograms / cubic meter of cement, 160 to 200 kilograms / cubic meter of admixture, 1600 to 2000 kilograms / cubic meter of aggregate, 160 to 190 kilograms / cubic meter of water and 4 to 5 kilograms / cubic meter of additive. The slurry stickiness of the cement is 150 to 600 MPa.s, and the initial setting time of the cement is 8 to 9 hours. The concrete mixture can adopt the conventional construction method to carry out the construction, including the common concrete vibrating method which adopts the slump to control, and can also adopt the construction method which adopts the slump flow to control. The concrete mixture is completely applicable to a high column, the height of which ranges from 2 meters to 15 meters, and adopts the slump flow to control the cast-place construction. The standard of the annex 1 is adopted to detect the constructed column, thereby completely conforming to the related regulations.

Description

technical field [0001] The invention relates to a cement concrete composition, in particular to a cement concrete composition suitable for pouring construction with expansion degree control. Background technique [0002] The cement concrete composition is the precursor of the concrete entity, and its components include raw materials such as cement, admixtures, and aggregates. With the rapid development of urban construction, columns in large buildings are often as high as several meters or even tens of meters, and the construction method of pouring with slump control is usually used, and its quality cannot be guaranteed. [0003] Conventional cement concrete compositions are simply not suitable for pouring cement concrete compositions into formwork frames using expansion control. For the cement concrete composition used for pouring construction with expansion control, not only the strength of the formed concrete needs to be considered, but also the fluidity and cohesion of ...
