【摘要】 本论文根据现行的GB15229—94《轻集料混凝土小型空心砌规范》研制出的粉煤灰、自然煤矸石混凝土小型空心砌块,用于多层建筑的承重墙。(1)根据均匀设计理论,设计出该砌块的最佳配合比,并检验抗压强度、表现密度、吸水率、相对含水率、软化系数、炭化系数、抗冻强度损失、抗冻性质量损失等技术性能指标,完全符合《规范》要求。(2)利用BP神经网络对该砌块的抗压强度进行了预测。(3)利用试验数据分析粉煤灰渗入量对抗冻性的影响,得出影响情况曲线。(4)对该试验成果进行了推广在阜新广厦建材有限公司投入生产,该砌块已经应用于多层建筑。更多还原

【Abstract】 According to the present《Specifications for design of small-sized hollow block of concrete with hight weight aggregates》(GB15229--94),a small—sized hollow block of concrete with flyash、 self-burning coal stone aggregates is obtained for sustaining weight walls of multistory buildings. Firstly,according to uniform design philosophy,designed the optimum mix of the block , and some technical performance intex such as the compressive strength 、 apparent density、water absorption、 percent moisture content 、oftening coefficient 、 charring coefficient 、the loss of freezing resistance strength、the loss of freezing resistance quality ect. are checked ,all of them meet with the specifications. Secondly, the compressive strength of the block is forcasted with BP nerve internet. Thirdly , with analyzed the influence of the amount of adding to flysh on the freezing resistance utilizing the test data,and obtained the curves. Finally,we have popularized the test result in the Limited Company of FuXin Construction Material ,the kind of block has been produced ,and it has been ultilized at the site construction.更多还原
