近年来在机器、设备和仪器生产中已开始利用混凝土和钢筋混凝土代替金属。例如,在动力机器制造中钢筋混凝土(包括混凝土)用于制造大能量水压透平的螺旋室,在畜牧机器制造中用于制造畜牧和饲料生产不同设备的支撑、板、底座、荷重。机器和设备采用钢筋混凝土构件比用金属 In recent years, concrete and reinforced concrete have been used instead of metals in the production of machinery, equipment and instruments. For example, in the manufacture of power machinery, reinforced concrete (including concrete) is used in the manufacture of large energy hydraulic turbine spiral chambers, and in animal husbandry machinery manufacturing, it is used to produce livestock, feed, and supports, plates, foundations, and loads for various equipment.
