泡沫混凝土型块填充板的试验与有限元分析

Experimental Study and Finite Element Analysis of Castinsitu Slab with EPSblock

摘要:

将废旧聚苯乙烯泡沫塑料(EPS)回收后破碎成3～8 mm大小的颗粒,与水泥浆和胶粉溶液按一定的配合比均匀拌合成聚苯乙烯泡沫混凝土,并制成中心对称的圆环体型块填充在现浇双向板的中性轴部位,可以节省大量混凝土,降低造价.用有限元软件ANSYS对此新型现浇EPS混凝土型块填充板进行静载作用下的非线性分析,结果表明其性能优越,有推广潜力.

Abstract:

Polystyrene foam being recycled are broken into particles with the size of 3～8 mm which are mixed with cement and glue powder in a certain proportion into expanded polystyrene foam concrete and are made into the shape of torus with centersymmetric blocks that are filled in neutral axis location of insitu twoway slabs.A lot of concrete can be saved and the cost reduces accordingly.And this new castinsitu slab with EPSblock under dead load is analyzed through the finite element analysis software ANSYS.Results show that the slab with EPSblock is of good performance which is prospecting in development.
