轻质自保温陶粒蒸压加气混凝土试验研究

Lightweight Self-conserving Heat Ceramsite Autoclaved Aerated Concrete Research

目前蒸压加气混凝土砌块存在自身强度低、自保温性能差、易开裂等现象。本文通过对陶粒蒸压加气混凝土原材料优化设计、生产工艺参数调整、以及陶粒对加气混凝土浆体混合料和易性影响,结合陶粒蒸压加气混凝土的增强作用机理和减缩作用机理分析,利用正交设计试验方法,研制出立方体抗压强度8.8 MPa、干燥收缩值0.156 mm/m、导热系数0.127 W/(m.k)的陶粒增强蒸压加气混凝土。

Autoclaved aerated concrete block,this paper has its deformation coefficient of large volume,low water absorption,own strength,easy cracking and other characteristics,through the optimization design of autoclaved aerated concrete raw materials,production process parameters adjustment,combined with ceramsite,the enhancement mechanisms of autoclaved aerated concrete and shrinkage effect mechanism analysis,Developed the cube compressive strength8.8MPa,drying shrinkage value of0.156mm/m,coefficient of thermal conductivity is0.127W/(m.k)ceramsite reinforced autoclaved aerated concrete.
