水泥抗压试验机公式计算
试件的抗折强度ff(Mpa)按下公式计算:
ff =FL/bh2
式中ff —混凝土搞折强度(Mpa)
F—试件破碎荷载(N)
L—支座间跨度(mm)
h—试件截面高度(mm)
b—试件截面高度(mm)
抗折强度计算精确至0.1Mpa
技术参数:
1、大荷载: 300KN
2、示值相对误差: ±1%
3、小分辨值: 0.01KN
4、油压大压强: 25Mpa
5、抗折辊直径: φ30mm
6、抗折辊间中心距 φ165mm
7、上抗折辊间中心距 150mm
8、上抗折辊间中心距 450mm(可调)
9、压力板直径: φ160mm
10、上下压板间净距: 180mm
11、活塞直径×大行程: φ125×100mm
12、电动机功率: 0.75KW
13、外形尺寸: 840×530×1450mm
14、净重: 550kg
