秸秆是一种保温性能非常好的材料，并且是一种每年可再生的资源，把这种材料应用于建材领域，研究节能立废的新型墙体材料，具有促进建筑结构工业化快速发展和节约能源、减少环境污染的重要意义。本文在秸秆混凝土中分别加入粉煤灰和硅灰，通过试验研究秸秆混凝土试块的导热系数以及抗压强度，研究发现粉煤灰的掺量越多，试块的保温性能越好，但其抗压强度越低；掺有硅灰的试块，硅灰的掺量越大其抗压强度在一定范围内越高。
秸稈是一種保溫性能非常好的材料，併且是一種每年可再生的資源，把這種材料應用于建材領域，研究節能立廢的新型牆體材料，具有促進建築結構工業化快速髮展和節約能源、減少環境汙染的重要意義。本文在秸稈混凝土中分彆加入粉煤灰和硅灰，通過試驗研究秸稈混凝土試塊的導熱繫數以及抗壓彊度，研究髮現粉煤灰的摻量越多，試塊的保溫性能越好，但其抗壓彊度越低；摻有硅灰的試塊，硅灰的摻量越大其抗壓彊度在一定範圍內越高。

Straw is a renewable resource with excellent thermal performance .This material was used in the field of build-ing materials .Here ,to develop new building materials for walls on the concept of energy saving and waste utilization . This new material could promote the industrialization development of building structures ,and it is of great essence to en-ergy saving and pollution reduction .In the experiments of thermal conductivity coefficient and compressive strength ,fly ash and silica fume were added to the straw concrete mix respectively ,it was found that the higher dosage of fly ash ,the better heat preservation performance of the test piece ,but the lower the compressive strength;with the test pieces added with silica fume ,the greater the content of silica fume ,the higher the compressive strength within a certain range .
