一块标准砖头的尺寸是多少?
中国标准的粘土砖尺寸是240×115×53mm,加上砌筑用灰缝的厚度8~10mm,正好4块砖长加灰缝为1m,8块砖宽加上灰缝为1m,16块砖厚加上灰缝为1m,合起来方1m3砖砌体。该模数尺寸很好,因此称其为“标准砖”。4×8×16=512(块)。砌体中每立方米需用砖512块标准砖?(砂浆用量:1-0。24×0。115×0。053×512=0。748m3)。 其它砖的模数尺寸也都是按这个思路走的。
普通砖的尺寸是多少?
普通砖的外形为直角六面体,公称尺寸为:240mm×115mm×53mm。按技术指标分为优等品(A)、一等品(B)及合格品(C)三个质量等级。普通砖的标准外行尺寸为240*115*53毫米,在加上10毫米砌筑灰缝,4块砖长或8 块砖宽、16块砖厚均为1米。1立方米砌体需砖512块。

国家标准G *** 5101-2017《烧结普通砖》规定,凡以黏土、页岩、煤矸石和粉煤灰、建筑渣土、淤泥、污泥等为主要原料,经成型、焙烧而成的砖,称为烧结普通砖。 需要指出的是,烧结普通砖中的黏土砖,因其毁田取土,能耗大、块体小、施工效率低,砌体自重大,抗震性差等缺点,在我国主要大、中城市及地区已被禁止使用。需重视烧结多孔砖、烧结空心砖的推广应用,因地制宜地发展新型墙体材料。利用工业废料生产的粉煤灰砖、煤矸石砖、页岩砖等以及各种砌块、板材正在逐步发展起来,应将逐渐取代普通烧结砖。
