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。
解：
一块砖的标准尺寸是：长=240毫米，宽=115毫米，厚=53毫米
标准砖，指的是尺寸为240mm×115mm×53mm的实心标准砖
密度为1800~1900kg/m3 ，一立方米标准砖529块 。
机制标准砖240*115*53.其它的空心砌块,还有很多.
