Abstract

Abstract

The plant-fiber-reinforced alkali-activated-slag cementitious material is a kind of new green building material with a great application prospect. The application of industrial and agricultural wastes such as slag and straw can be not only reduce the cost of construction cost, but also obviously improve the anti-cracking performances of the block masonry. The compressive performance tests were conducted on 60 pieces of block masonry constructed by different fiber-reinforced alkali-activated-slag cementitious material at normal temperature and after high temperature. The test result showed that the strength grades of fiber-reinforced block masonry constructed by plantfiber,polypropylene fiber or microsteel fiber were equivalent to the concrete block masory of MU7.5, MU10 and MU15 at normal temperature respectively. The plant fiber still had a certain toughening effect on masory after being subjected to 800℃. By means of regression analysis, an equation for calculating the compressive strength of plant-fiber-reinforced block masonry after being subjected to high temperature was constructed.
