Helicopter Concrete

Helicopter Concrete / Screed

Before the concrete pouring, a sketch will be prepared in the area where the ground concrete will be applied and concrete pouring planning will be made. In concrete casting planning, necessary precautions will be taken for structural joints, and necessary arrangements will be made for steel reinforcement for concrete sitting on the soil. It will be checked that all the requirements specified in the preparation phase for concrete pouring have been fulfilled.

Concrete pouring will be carried out by means of anos to be determined in accordance with the dimensions of the area to be cast for field and floor concretes. The steel formworks that will serve as anodes are 3.00 meters long and 4.00 cm thick. The height of the steel molds will be adjusted according to the concrete finish elevation. The placement of the anodes will be done in line with the level control using optical or laser measurement systems. Attention will be paid to the cleanliness of the steel molds to be used. Seam anchors will be formed between the anchors at appropriate intervals perpendicular to the anchors. Concrete pouring will be done continuously within the ano. Cold joints will not be made in any section until the ano is finished. In cases where the poured concrete depth is more than 10 cm, the concrete shall be compacted with submersible vibrators and all concrete surfaces shall be finished with vibrator screed. During concrete pouring, level controls will be made with aluminum gauge. Concrete surface will be finished with helicopter (disk) finishing and steel trowel finishing. Floor concretes will be made by using natural mineral aggregate hardener on a single layer of wire mesh steel to be determined by using rust allowances on the existing flooring and thermal insulation in the floor concretes (above the slab) inside the building. Joint Cutting and Joint Filling shall be done as described in the relevant specifications. Polyethylene cover will be laid on the existing filling under the concrete in the Outdoor Concrete, concrete pouring will be made after the mesh steel is laid and the concrete surface will be finished as smooth or brushed (line textured) according to the desired texture on the surface.
