山东省大量生产、使用的实心粘土砖一年就“吃掉”良田4万多亩,而国家明文要求推广的利用石膏、淤泥、电厂排放的煤矸石、粉煤灰等材料生产的具有强度高、保暖性能好等优点的新型墙体材料,却因每吨30元左右的成本差价在市场上竞争不过粘土砖,仅占三成市场份额。这仅是科技创新在建筑业中“碰壁”的一个缩影。我们不禁要问:建筑业离科技创新还遥远吗?
The mass production and use of solid clay bricks in Shandong Province have “eaten” more than 40,000 mu of fertile farmland in a year, while the state explicitly requires the promotion of the use of gypsum, silt, coal gangue discharged from power plants, fly ash and other materials with high strength , Good thermal properties such as the advantages of the new wall materials, but because of the cost of about 30 yuan per ton difference in the market, but clay bricks, only 30% of the market share. This is only a microcosm of technological innovation in the construction industry “runway.” We can not help asking: Is construction still far from technological innovation?
