整体浇注的混凝土支护具有成本低,机械强度高的特点,同时在生产中可以广泛采用机械化作业。利用比表面积为2800—3200厘米~2/克的磨细粒化高炉矿渣和稠度为1.1—1.3克/厘米~3的低模数水玻璃可以制备B-10—B-100级高活性矿渣碱混凝土。生产这种混凝土可以利用粘
The integrally cast concrete support has the characteristics of low cost and high mechanical strength, and can be widely used in the production of mechanized operations. The B-10-B-100 grade high activity slag base can be prepared by grinding granulated blast furnace slag with a specific surface area of 2800-3200 cm-2/g and low modulus water glass with a consistency of 1.1-1.3 g/cm-3. Concrete. Producing this kind of concrete can make use of sticky
