为了节约钢材,降低建筑物的自重,我们开展了用玻璃纤维代替钢筋制造加筋的轻混凝土制品的试验研究。一、轻混凝土配制(一)配制原则轻混凝土的配制是按如下两个原则进行的: 其一,尽量利用工业废料,减少水泥的耗用量;其二,为了降低混凝土的容重,改善其隔热、抗冻等性能,采取在混凝土中掺加轻骨料和加气剂(表面活性剂)等措施。(二)轻混凝土配合比轻混凝土的原材料有:水泥、煤渣,活化煤渣、粉煤灰、加气剂和水。它们之
In order to save steel and reduce the weight of the building, we conducted a pilot study of the use of glass fiber instead of steel to manufacture reinforced concrete products. First, the preparation of light concrete (a) the principle of the preparation of light concrete is based on the following two principles: First, make full use of industrial waste, reduce the consumption of cement; Second, in order to reduce the bulk density of concrete, improve its separation Heat, antifreeze and other properties, to take in the concrete mixed with light aggregates and air additives (surfactants) and other measures. (2) Light-weight concrete The raw materials of light-weight concrete include: cement, coal slag, activated coal residue, fly ash, air entraining agent and water. They are
