Improving the maniifacturability of the reinforced concrete structures production by using lightweight filling materials

摘要

The article shows the feasibility of improving the maniifacturability of the prefabricated monolithic floors reinforced concrete structures production by reducing their own weight. In the works of the authors, the reduction of the sole weight and the cost is achieved by using the light materials filling the inter-gully space. It is proposed to use gas-concrete, polystyrene foam concrete blocks or limestone-limestone blocks as a local building material in the Crimea with such materials for the advanced system MARCO. Due to that, the cost of the interfloor overlap device has been reduced by approximately 10%. In addition, there is an additional cost reduction also due to the improved ergonomic work performance, increasing the productivity of workers by 6%. Innovative design and technological solutions are also presented, replacing the part of heavy concrete in a flat floor slab with hollow cores made of lightweight artificial materials-expanded polystyrene, polyethylene or cement wood.
