“…The void slab system (Figure 1) is a new development that enhances the structural performance of a slab through reduced weight and increased stiffness [19][20][21]. It is a method to improve the strength of a slab in supporting a load, through the effective utilisation of its moment of inertia.…”

The purpose of this study is to verify the environmental performance of the novel Void Deck Slab (VDS) system developed by the authors. The proposed VDS is a void slab system with enhanced design features that improve the constructability of the system through the elimination of additional works required to connect the void formers with the anchoring devices. The Life Cycle Assessment (LCA) technique was adopted to assess the carbon dioxide emissions of the void slab system with reference to the ordinary reinforced concrete slab. The system boundary of this study ranged from raw materials to pre-operation phase, in accordance with ISO 14044. The total CO2 emissions of the ordinary reinforced concrete slab and the void slab system were 204,433.06 and 151,754.75 kg CO2-eq, respectively, which equated to about 34% less emissions for the void slab system. In the case of the ordinary reinforced concrete slab, moulds accounted for approximately 62% of CO2 emission, followed by concrete (~34%). The main source of CO2 emissions for the void slab system was concrete that accounted for ~50%, followed by moulds and deck plates that accounted for roughly 27% and 19%, respectively. In the case of the void slab system, void formers would enable a lower amount of concrete, as well as the self-weight of the slab. Besides, although the void formers filled a significant volume of the slab, the contribution to CO2 emissions was less than 1%.

“…Therefore, it is easy to cause large temperature difference between the inside and outside of the concrete. It is very difficult to maintain the vertical plane of the wallboard [2].Some effective methods used to control concrete cracks, such as the heat storage method, cannot be applied to the exterior wall of the basement. All these aggravate the plastic shrinkage deformation of the concrete.…”

To study and analyze the mechanical property of cast-in-situ concrete light pipe column wallboard, the small deflection theory of thin board was used, aiming to deduce the deflection and internal force expression of cast-in-situ concrete light pipe column wallboard under action of the triangular load and uniform load. The wallboard used the form of three simply supported and one fixed edges. Finally, a table of related coefficients of deflection and internal forces was formed. The ABAQUS finite element analysis software was used to analyze the influence of the factors such as volume hollow ratio, pipe length, load form, boundary condition, axial compression ratio and its action position on the bearing capacity of cast-in-situ concrete light pipe column wallboard. The calculation result showed that the loading capacity of PVC pipe with the length of 1500 mm was close to one with the length of 1000 mm. When the length of PVC pipe was between 1000 mm and 1500 mm, the bearing capacity of the wallboard was hardly affected by the length of the PVC pipe. It is concluded that the PVC pipe with a longer length can be selected to effectively reduce the influence of hydration heat of the concrete.
