烧结砖性能指标

[ 时间:2013-07-27 点击:1546 ]

① 形状尺寸。普通粘土砖为长方体,其标准尺寸为240mm×115mm×53mm,加上砌筑用灰缝的厚度,则4块砖长,8块砖宽,16块砖厚分别恰好为1m,故每一立方米砖砌体需用砖512块。
② 强度等级。普通粘土砖的强度等级根据10块砖的抗压强度平均值、标准值或最小值划分,共分为MU30、MU25、MU20、MU15、MU10五个等级,在评定强度等级时,若强度变异系数δ≤0.21时,采用平均值——标准值方法;若强度变异系数δ>0.21时,则采用平均值——最小值方法。各等级的强度标?#21152;?#31526;合下表规定值。
其具体要求如下表所示。

 ③ 抗风化性能。抗风化性能是普通粘土砖重要的耐久性指标之一,对砖的抗风化性能要求应根据各地区的风化程度而定(风化程度的地区划分详见GB/T5101-1998)。砖的抗风化性能通常用抗冻性、吸水率及饱和系数三项指标划分。抗冻性是指经15次冻融循环后不产生裂纹、分层、掉皮、缺棱、掉角等冻坏现象;且重量损失?#24066;?#20110;2%,强?#20154;?#22833;?#24066;?#20110;规定值。吸水率是指常温泡水24h的重量吸水?#30465;?#39281;和系数是指常温24h吸水率与5h沸煮吸水?#25163;?#27604;。

?#29616;?#39118;化区中的1、2、3、4、5等5个地区所用的普通粘土砖,其抗冻性试验必须合格,其他地区可不做抗冻试验。
④ 石灰爆裂。原料中若夹带石灰或内燃料(粉煤灰、炉渣)中带入CaO,在高温熔烧过程中生成过火石灰。过火石灰在砖体内吸水膨胀,导致砖体膨胀破坏,这种现象称为石灰爆裂。GB/T5101-1998规定,优等品不?#24066;?#20986;现最大破坏尺寸大于2mm的爆裂区域?#28784;?#31561;品不?#24066;?#20986;现最大破坏尺寸大于10mm的爆裂区域;合格品中每组砖样2~15mm的爆裂区不得大于15处,其中10mm以?#31995;?#21306;域不多于7处,且不得出现大于15mm的爆裂区。
⑤ 泛霜。是指砖内可溶性盐类在砖的使用过程中,逐渐于砖的表面析出一层白霜。这些结晶的白色粉状物不仅影响建筑物的外观,而且结晶的体积膨胀?#19981;?#24341;起砖表层的疏松,同时破坏砖与砂浆层之间的粘结。
GB/T5101-1998还规定,优等品不?#24066;?#26377;泛霜现象,合格品中不?#24066;?#20986;现?#29616;?#27867;霜,且不得?#24615;?#27424;火砖、酥砖和螺旋纹砖。
⑥ 质量等级。
根据国家标准GB/T5101-1998《烧结普通砖》的规定,普通粘土砖的技术要求包括形状、尺寸、外观质量、强度等级和耐久性等方面。根据尺寸偏差和外观质量、泛霜和石灰爆裂分为优等品(A)、一等品(B)和合格品(C)3个等级。普通粘土砖的孔隙率约为30%,吸水率18%~20%左右,表观密度为1800kg/m左右
