Physico-mechanical Behaviors and Durability of Heated Fiber Concrete

The objective of the present manuscript is to describe impact polypropylene fibers on behavior heated concrete subjected heating and cooling cycles at temperatures 200, 450 600 °C respectively for six hours, through a series experimental tests mass loss, water absorption, porosity, compressive tensile strength. For this purpose, mixes were prepared with water/cement ratio incorporation rate varying from 0.5 1.5%. These added in order improve thermal stability prevent splitting. results show that considerable loss strength was noticed all tested specimens. relative strengths concretes containing higher than those without fibers. Also, greater compared when increasing temperature. flexural more sensitive elevated rapid increase porosity observed fiber-reinforced reference concrete. Furthermore, absorption by proportional fiber content Doi: 10.28991/cej-2021-03091745 Full Text: PDF
