一、保温砌块和墙板已形成行业规模保温砌块和墙板目前已形成加气混凝土砌块为先导、轻集料混凝土制品强势崛起的行业态势。近年来,在充分总结我国外墙保温技术和行业发展基础上发展起来的自保温墙体技术,已经遍及严寒、寒冷、夏热冬冷等地区。加气混凝土和砂加气砌块迅速覆盖寒冷和夏热冬冷地区各省市,企业数量和单个企业生产规模同步高速增长。可喜的是,作坊式小工厂已受到规模化企业的市场挤压和技术排斥,行业开始呈现良好的发展态势。而更为值 First, the insulation block and wallboard has formed the industry-scale insulation block and wallboard Aerated concrete block has formed a pilot, light aggregate concrete products strong rise of the industry trend. In recent years, fully summed up our external wall insulation technology and industry development based on the development of self-insulation wall technology, has been covered in cold, cold, hot summer and cold in summer and other regions. Aerated concrete and sand aerated blocks quickly covered the provinces of cold and hot summer and cold winter regions, the number of enterprises and the scale of production of a single enterprise simultaneously increased rapidly. The good news is that the small factory-based workshop has been squeezed by the market scale and technical exclusion, the industry began to show a good momentum of development. And more value
