当前,房屋建筑的发展,由于建筑材料严重不足,受到很大限制。虽然国家已将发展建筑材料列为重点,建材部门也在作很大的努力,但由于财力物力的限制,供需矛盾在相当长时间内很难解决。我国地大物博,工业废料和自然资源极其丰富,如果积极开发利用,无疑对扩大建筑材料来源,促进建筑业发展是切实有效的。 At present, the development of housing construction is severely limited due to the severe shortage of building materials. Although the country has made the development of building materials a priority, and the building materials sector is also making great efforts, due to the constraints of financial and material resources, the contradiction between supply and demand is difficult to solve for a long time. China’s vast land and resources, industrial waste and natural resources are extremely rich. If it is actively developed and utilized, it will undoubtedly be effective in expanding the sources of building materials and promoting the development of the construction industry.
