纤维混凝土夹心秸秆压缩块砌块霉变效果实验研究

Experimental Study on the Mildew Effect of the Fiber Reinforced Concrete Block Filled With Compressed Blocks of Straw

将纤维混凝土夹心秸秆压缩块砌块放入恒温恒湿箱中,模拟高温高湿环境,在温度为30℃,相对湿度为90%条件下放置10d,然后将内部的小麦秸秆砌块取出,观察其表面变化并利用平板菌落计数法测量霉菌数量。实验表明,在此条件下小麦秸秆砌块并没有发生霉变,表面没有菌落生成。

The fiber reinforced concrete block filled with compressed blocks of straw is put in the box with constant temperature and hu-midity,simulating the environment of high temperature and high humidity.Ten days later,in the conditions whose temperature and relative humidity is 30℃and 90%,the wheat straw bricks are taken out,observing the surface changes and measuring the number of mildew by the plate colony count method.The experimental study proves the wheat straw bricks don＇t happened mildew in this condition and don＇t generate colonies in the surface.
