Özet:

 


In this study, the influence of elevated
temperature on the physical and mechanical properties of concrete produced by
expanded clay aggregate and calcium aluminate cement (CAC) was investigated.
For this purpose three different mixture were prepared. First mixture was
produced by using ordinary Portland Cement (OPC) and natural aggregate. Second mixture
was prepared by OPC and expanded clay aggregate. Third mixture was produced by
using CAC and expanded clay aggregate. The water-cement (w/c) ratio used in the
mixtures was determined as 0.50. The concrete specimens were heated in an
electric furnace up to 200, 400, 600, 800 and 1000 °C and kept at these
temperatures for one hour. Two cooling regimes (slow and fast) were used. The
residual compressive strength, weight loss, water absorption and porosity ratio
and ultrasonic wave velocity values of the specimens were measured. The test
results show that exposing to elevated temperatures adversely affected the
mechanical and physical properties of the specimens containing OPC and natural
aggregate. However, the lightweight concretes produced by expanded clay
aggregate demonstrated better performance. Fast cooling (FC) method caused
significant strength losses than slow cooling (SC) method.
