The Investigation on The Effects of Different Temperature Types on Concrete Containing Expanded Perlite Aggregate
Abstract
This study was carried out to investigate the effect of high temperature by using fire and oven on the physical and
mechanical properties of three different concrete classes that are C16/20, C20/25 and C40/50 also, concrete
samples are manufactured as containing expanded perlite aggregate (EPA) and not containing perlite aggregate.
The reference temperatures are specified as 22 ºC, 100 ºC, 300 ºC, 500 ºC in the oven and the case of fire. These
temperatures are applied to a sample having 100x100x100 mm3 dimensions. The tests made on each concrete type
are weight per unit volume, compressive strength, and ultrasonic pulse velocity. Consequently, the test results
come out statistically different of the concrete samples affected by high temperature according to if the heat is
applied by the oven or fire, the compressive strength of the samples decreases as the high-temperature degree
increases in a compressive strength test. Besides that, while the loss of compressive strength of oven samples at
500 ºC comes out approximately 60 %, for samples applied fire is approximately 10%.
