摘要
结合具体实例,介绍了透水模板布在干旱风沙地区混凝土施工中的应用,结合该地区环境特征和透水模板布性能进行了分析,指出使用透水模板布后,对于不同配合比的混凝土试样,表观质量及密实度得到不同程度改善,回弹强度相应提高,渗透系数降低,表层混凝土微观孔结构得到改善,整体抗渗性能相应增强。
Combining with the specific example,this paper introduced the application of controlled permeability formwork in concrete construction of arid sandy area,made analysis combining with the environment characteristics of this area and the performances of controlled permeability formwork,pointed out that after using controlled permeability formwork,for concrete samples with different mixture ratios,apparent mass and density were improved with different degree,the rebound strength was corresponding improved,permeability coefficient was reduced,the micro pore structure of surface concrete was improved,the overall impermeability was corresponding enhanced.
