摘 要:现提倡绿色材料,节能环保新型建材,采用粉煤灰、陶粒等材料配制的陶粒混凝土,可以降低结构自重,提高抗震性能。本文进行了正交试验研究,得出对陶粒混凝土抗压强度影响程度的因素由大到小分别为水灰比、砂率、粉煤灰掺量,并进而得出最优配合比;对陶粒混凝土受压破坏形态进行了分析,结果表明,水泥砂浆与陶粒的界面破坏和陶粒全截面断裂破坏是陶粒混凝土受压破坏的主要形态。
Abstract: Energy saving and environment protection in buildings and building materials are advocated nowadays. Using fly ash, ceramsite and other materials to prepare the ceramsite concrete can reduce weight and improve seismic performance.The compressive strength of ceramisite concrete is studied by orthogonal test, the conclusion shows that the order of factors of compressive strength is: water-cement ratio, sand rate and the mixing amount of fly ash, and then the optimal ratio is obtained. The failure mode of the ceramsite concrete is analyzed, and there are two kinds of failure modes, the interface failure of the cement mortar and the whole cross section rupture of the ceramsite.
