Preparation and transportation of concrete during laser screed flooring

1 When preparing concrete for the laser screed flooring, technical control requirements such as raw material, slump and human mold temperature should be proposed according to the concrete temperature control and anti-crack control construction scheme.

2 For seamless construction of super-large area concrete ground works, ready-mixed concrete should be used. When ready-mixed concrete is difficult to supply, concrete can be mixed on site.

3 The production capacity and transportation capacity of the ready-mixed concrete production unit shall meet the technical requirements for design and construction, and the concrete quality shall comply with the provisions of the current national standards. The quality of on-site mixing concrete should comply with the current national standards.

4 The same batch of concrete should be supplied by the same manufacturer. When supplied by many manufacturers, the concrete should meet the same principle of raw material, mix ratio, material measurement grade, and the same preparation process and quality inspection level.

5 During concrete transportation, the concrete should be controlled without segregation and delamination, and the performance of the concrete mixture should be controlled to meet the construction requirements.

6 Concrete transportation should be carried out by mixing trucks. The transportation requirements should comply with the current national regulations, and should have sun protection and cold protection facilities.

7 When pumping concrete, concrete transportation should ensure continuous pumping of concrete and should comply with the relevant provisions of current industry standards.
