Using low-price local raw material in stead of high-price material was described in the paper The glaze formulation Was improved and the twice firing process was applied And therefore cost was reduced,the quality of the products were improved. 主要叙述该厂采用部分当地低质原料取代外地高价原料,改进坯釉配方,采取分别施底釉和面釉二次烧成工艺.达到了降低成本提高产品质量的目的,并收到较好的经济效益。 The test study on cement-soil used for silt-dam has been carried out on the Yan He river basin training project.The results provide basic data of cement-soil used for seepage preven tion of irrigation canal and shield or cushion of silt-dam. It helps the spreading of the use of this low-price local material. 结合陕北延河流域治理项目,进行了过水土坝护面与垫层材料─—水泥土的试验研究。为水泥土在西北地区的渠道防渗、过水土坝护面与垫层等方面的应用提供了基本的技术资料,有利于这种价格低廉的地方性建筑材料的推广使用。
