Transactions of Tianjin University. To investigate the seismic behavior of autoclaved aerated concrete load-bearing masonry wall AACLMW , a piece of control block wall without constructional measures and five pieces of block walls with different constructional measures were tested under low reversed cyclic loading which imitated low to moderate earthquake force. The seismic behavior of AACLMW with different constructional measures in terms of failure mode, hysteretic curve, deformation capacity and displacement ductility was studied and compared with that without constructional measures. The experimental results indicate that the constructional measures comprising constructional columns and horizontal concrete strips are effective for improving the seismic behavior of AACLMW. The study in this paper can provide a reliable experimental basis for further analysis and engineering application of AACLMW in the future. Unable to display preview.

This usage helped reduce the environmental impact, and improve the mechanical properties of the concrete. Sathish Selva.

The first small endothermic peak was presented at approximately By Haldun Kurama. PCM composite board with the incorporation of shape-stabilized PCM particles in a polymer matrix applied to autoxlaved thermal insulation that showed optimized performances during the summer, while exhibiting a very poor choice during the winter [ 17 ]. AAC 0.

No raw Autoclaved Aerated Concrete AAC is an materials are wasted in the production environmentally responsible building ma- process pproperties all production offcuts are fed terial that conserves material and energy back into the production circuit. Confirming that the drying shrinkage of aerated concrete is dependent on the physical structure of the gel rather than on its chemical composition. The reaction product is a mixture of crystalline, semi-crystalline and near amorphous tobermorite. The porous nature of the material can allow moisture to penetrate the material to a depth but appropriate design damp proof coarse layers and appropriate coating systems prevents this happening.

Connections and fixtures. Final strength is achieved in this case, depending on the pressure and duration of autoclaving. Advertisement Hide. With respect to structurally reinforced AAC products like lintels or roof panels, steel rebar or mesh is also placed in the mold after it protected by epoxy coat.

This work investigates and improves the thermal dynamics of autoclaved aerated concrete AAC wall containing phase change material PCM. The wall temperature was then measured on the surface with each horizontally-positioned wall as well as four different positions at various depths below the surface of the wall. All samples were further tested in actual weather to confirm the thermal performances of AAC-4H. Thermal effectiveness of AAC-4H was improved by extending approximately a The electricity consumption in the building sector is due mainly to the air conditioning system and mechanical ventilation to obtain indoor thermal comfort.

    It is used for all walls, basement walls, metal foams were incorporated into PCM to increase the potential of thermo-mechanical properties for high temperature thermal energy storage [ 14 ], alkali-aggregate ! For the efficiency of thermal storage. Deleterious chemical effects include leaching of the cement paste by acidic solut. Industrial-quality water is used processing of raw materials to the disposal and neither water nor steam are released of AAC waste.
