摘要：

As an agricultural product, wheat straw contains considerable amounts of SiO2: When burned it leaves an ash very rich in SiO2 that has a pozzolanic character. Wheat is an important agricultural product in Turkey. In this study, wheat straws are ground to 1-5-mm size and subjected to preburning treatment. The preburned material is later burned in controlled conditions for 5 hours at 570 and 670 degrees C. The ash is cooled suddenly and ground to 90-200 mu size. The standard test specimens are produced from ash and mechanically, chemically, and physically tested for determination of its pozzolanic properties. It is obtained that the ash has pozzolanic activity. (C) 1999 Elsevier Science. All rights reserved.
