Assessing the Impact of Cement Content and Type on the Durability of Roller Compacted Concrete Using NDT

Abstract

The primary objective of this research is to study the durability of roller compacted concrete (RCC) samples that were constructed in the laboratory using roller compactor. A total of 60 slab sample of (38×38×10) cm have been constructed using the roller device, cured for 28 days, then 180 sawed beams were obtained from RCC slab. The specimens were subjected to 60 cycles of each of the durability testing parameters including freezing and thawing, soundness against sulfate attack cycles and wetting and drying. The effect of implementation of two types of cement (OPC and SRPC) on the durability of RCC was investigated using the nondestructive test technique (NDT). The results indicated that RCC that contain SRPC has superior quality when compared to RCC that contain OPC after durability testing. Based on the testing results, it was concluded that the resistance of RCC specimens to freezing and thawing, wetting and drying and sulfate attack test increase as cement content increase.
