计算用粘土实心砖(240mm×115mm×53mm)砌筑1m31/2砖厚内墙(灰缝10mm)所需砖、砂浆定额用量(砖、砂浆损耗率按1%计算)
解:砖净耗量(块)=1/[(砖长+灰缝)×(砖宽+灰缝)×(砖厚+灰缝)]=552.100(块)
砂浆净耗量=砖墙体积一砖体积=1-0.24×0.115×0.053×552.100=0.192(m3)
砖消耗量(块)=砖净用量+砖损耗量=砖净用量×(1+损耗率)=552.100×(1+1%)=558(块)
砂浆消耗量=砂浆净用量×(1+损耗率)=0.192×(1+1%)=0.194(m3)
答:砌筑1m31/2砖墙定额用量砖558块,砂浆0.194m3
