我公司位于厦门市,地处亚热带,平均气温较高,湿度较大。根据这一特点,历年来,我们利用火力发电厂排出的煤渣为主要原料,加适量的碱性激发剂(生石灰或消石灰)及水,经轮碾机搅拌、破碎、活化,加压成型,在常温下自然养护28天左右,可制得具有抗压强度75公斤/厘米~2,抗折强度20公斤/厘米~2以上的硅酸盐砖。1958年试制成功用自然养护方法生产煤渣砖,1960年在莲板水泥制品厂试生产并少量推广,1965年新建杏林煤渣砖厂。通 My company is located in Xiamen City, located in the subtropical area, with high average temperature and high humidity. According to this feature, over the years, we have used the coal slag discharged from coal-fired power plants as the main raw material, added appropriate amount of alkaline activators (calcaree or hydrated lime) and water, and stirred, broken, activated and pressed by roller mills. Under natural temperature for about 28 days, a silicate brick with a compressive strength of 75 kg/cm~2 and a bending strength of 20 kg/cm~2 can be obtained. In 1958, trial production successfully used natural conservation methods to produce coal cinder bricks. In 1960, it was trial-produced at the Lin Ban Cement Products Factory and a small amount was promoted. In 1965, Xinglin Cinder Brick Factory was built. through
