摘要:研究了陶粒混凝土拌合物泌水、粉煤灰及骨料的掺量对轻质、高强陶粒混凝土内隔墙板表面气孔的影响。结果表明:陶粒混凝土拌合物泌水、粉煤灰及骨料的掺量对轻质、高强内隔墙板的表观质量有着重大的影响,泌水越严重则内隔墙板的表面大孔径气孔数量越多,表面气孔数的加权结果也越高,表观质量也相应的越差。陶粒掺量越多、河砂掺量越少,则陶粒混凝土内隔墙板的表观质量也相应的越差;而粉煤灰掺量的提高则有助于改善内隔墙板的表观质量。

Abstract:This paper studied the effect of mixture bleeding,content of fly ash and aggregate on the surface pores of lightweight high-strength ceramisite concrete hollow panel for internal partition wall.The results indicated that it had significant effect on the surface quality of pores.If the bleeding was more heavy,the big diameter pore’s number of the surface would be more,the surface pore’s weighting number would be more also,and the surface quality would be worse.The more contained ceramisite and lower contained sand,the worse the surface quality would be,and increasing the content of fly ash would be good to improve the surface quality.

陶粒混凝内隔墙板是以轻质陶粒、细集料、胶凝材料及外加剂、水等原料混合后经平模或立模工艺成型制作而成的,使用专用砂浆粘结、辅件定位,形成建筑物室内隔墙。陶粒混凝土内隔墙板具有质量轻、强度高、隔音性能好、可任意切割等特点,施工简便快捷,建造速度快,同时能提高建筑使用面积,是一种良好的环保节能板材,是工业化建筑及住宅产业化的主要部件和组成部分[1-4]。然而,陶粒混凝土内隔墙板在生产过程中,表面容易产生气孔、毛刺等缺陷,极大地影响了陶粒内隔墙板的外观和质量。……
