多(duo)孔(kong)磚(zhuan)是(shi)指(zhi)以(yi)粘土、頁巖、粉煤灰為主要原料，經成(cheng)型、焙燒而成(cheng)的多(duo)孔(kong)磚(zhuan)，孔(kong)洞(dong)率不小于(yu)(yu)15%~30%，孔(kong)型為圓孔(kong)或非圓孔(kong)，孔(kong)的尺寸(cun)小而數量(liang)多(duo)，具有長(chang)方形(xing)或圓形(xing)孔(kong)的承(cheng)重(zhong)燒結(jie)多(duo)孔(kong)磚(zhuan)，決(jue)不等同于(yu)(yu)只要在磚(zhuan)上開些洞(dong)。主要適用于(yu)(yu)承(cheng)重(zhong)墻體。
空(kong)心(xin)磚(zhuan)與多(duo)孔(kong)磚(zhuan)的區別就是磚(zhuan)體內涵(han)的孔(kong)洞(dong)數(shu)量(liang)(liang)、大小(xiao)不(bu)(bu)同(tong)，空(kong)心(xin)磚(zhuan)的孔(kong)洞(dong)大、數(shu)量(liang)(liang)小(xiao)，多(duo)孔(kong)磚(zhuan)的孔(kong)洞(dong)小(xiao)、數(shu)量(liang)(liang)多(duo)。兩(liang)者適用(yong)(yong)(yong)的場合也(ye)是不(bu)(bu)同(tong)的，多(duo)孔(kong)磚(zhuan)適用(yong)(yong)(yong)范圍廣(guang)，不(bu)(bu)管是承重(zhong)(zhong)(zhong)部位還(huan)是非承重(zhong)(zhong)(zhong)部位均可使用(yong)(yong)(yong)，而空(kong)心(xin)磚(zhuan)只能用(yong)(yong)(yong)于非承重(zhong)(zhong)(zhong)部位。
空(kong)(kong)(kong)心磚(zhuan)(zhuan)與多(duo)孔磚(zhuan)(zhuan)雖(sui)然(ran)在(zai)磚(zhuan)(zhuan)體(ti)的尺寸規(gui)格上有(you)(you)一定區別(bie)，但整體(ti)比例是差(cha)不多(duo)的。空(kong)(kong)(kong)心磚(zhuan)(zhuan)主要有(you)(you)燒結空(kong)(kong)(kong)心磚(zhuan)(zhuan)、玻璃空(kong)(kong)(kong)心磚(zhuan)(zhuan)等類別(bie)，而多(duo)孔磚(zhuan)(zhuan)有(you)(you)P型、M型等類別(bie)。空(kong)(kong)(kong)心磚(zhuan)(zhuan)的抗震性差(cha)不適合自建(jian)房用，多(duo)孔磚(zhuan)(zhuan)的裝飾性較差(cha)。
